A common, often hormonally-triggered skin condition characterized by pimples and inflamed skin.

Acne

Acne is a common skin condition that manifests as various types of bumps on the skin. These bumps can include blackheads, whiteheads, pimples, and deep, painful cysts and nodules. Apart from the face, it also affects the chest, back, and shoulders. While it's most common among teenagers, acne can affect individuals of any age group. Although it's not dangerous, severe acne can be painful and may also lead to permanent scars.

A condition causing hair loss in patches

Alopecia Areata

Alopecia Areata is a health condition that causes hair to fall out in small patches. It is an autoimmune disease where the body mistakes healthy cells for foreign substances, hence attacking hair follicles. This damage to the follicles leads to hair falling out, often in clumps the size and shape of a quarter. The degree of hair loss and regrowth varies greatly from person-to-person and is most common in people younger than 20, but children and adults of any age may be affected.

A common, non-contagious chronic skin condition creating itchy, inflamed skin

Atopic Dermatitis

Atopic Dermatitis, also known as eczema, is a chronic (long-lasting) disease that affects the skin. It is characterized by itchy, inflamed skin. While it primarily affects children, it can occur at any age and may follow a recurrent course – improving and worsening periodically. Although it's discomforting, it's not life-threatening and isn't contagious. Although its exact cause is unknown, it seems likely that it occurs due to a combination of genetic, environmental, and immune system factors.

A common but highly treatable form of skin cancer

Basal Cell Carcinoma

Basal cell carcinoma (BCC) is the most common form of skin cancer worldwide. While they may look similar to other skin blemishes, BCCs differ because they can cause significant damage by growing and spreading if left untreated. Nevertheless, it rarely metastasizes or moves to internal organs, meaning it has a high recovery rate when addressed promptly. Regular skin checks and early detection are keys to maintaining skin health.

A rare, chronic autoimmune skin disorder causing large, fluid-filled blisters

Bullous Pemphigoid

Bullous Pemphigoid is a chronic and relatively rare autoimmune skin disorder that results in the formation of large bullae or blisters filled with fluid, typically under the skin's surface. The condition often affects elderly individuals, notably around the age of 60 or older. This disorder involves a malfunction in the immune response that causes the body to attack its own skin tissue. Even though it can be pretty unpleasant and uncomfortable, it is generally not life-threatening and can be managed well with medical treatment. However, it sometimes may affect the mouth or eyes, which warrants prompt medical attention.

A common yeast infection often affecting the moist areas of the body

Candidiasis (Thrush)

Candidiasis, also known as thrush, is a fungal infection caused by a type of yeast called Candida. It commonly affects areas of the body naturally warm and moist, such as the mouth and throat, genitals, underarms, and underneath breast folds, but can sometimes invade the bloodstream, leading to potentially serious complications. It occurs when the body's defense mechanism is not working effectively, allowing the Candida yeast to multiply and cause infection. Although candidiasis can be uncomfortable and persistent, it is usually not serious and can be effectively treated.

A common, potentially serious bacterial skin infection

Cellulitis

Cellulitis is a common but potentially serious bacterial skin infection. It first appears as a red, swollen area that feels tender and warm to the touch. The redness and swelling can spread rapidly. As cellulitis can affect any part of the body, it's most often found on damaged or broken skin surfaces, such as a cut, insect bite, or surgical wound. Without treatment, the infection can spread to the lymph nodes and bloodstream, which can become life-threatening. Therefore, immediate medical treatment is essential.

Also known as 'Swimmer's Itch', a skin condition caused by parasitic worm infection

Cercarial Dermatitis

Cercarial Dermatitis, more commonly known as Swimmer's Itch, is an irritating skin condition caused by an allergic reaction to small worms or larvae called 'cercariae.' While this condition is self-limiting and generally resolves on its own, it can cause some distress due to the intense itching and unsightly rash it induces.

A highly contagious viral infection known for causing itchy, blister-like rashes

Chickenpox

Chickenpox, or varicella, is a highly contagious viral disease caused by the varicella-zoster virus. Though it's widely known for its distinctive itchy, blister-like rash, it's also accompanied by flu-like symptoms. It often affects children, though adults who haven't been previously infected or vaccinated can contract it. While typically a mild disease, complications, though rare, can occur and are generally more severe in adults.

A common viral infection characterized by small, painful blisters on the mouth or surrounding areas.

Cold Sore

Cold sores, also known as fever blisters, are small painful blisters that usually form near your mouth or on other areas of your face. These sores are caused by the herpes simplex virus (HSV-1), and while the symptoms may subside over time, the virus remains in your body throughout your lifetime. However, prompt care and attention can manage the symptoms and prevent future outbreaks.

An itchy, inflamed skin reaction caused by direct contact with a substance

Contact Dermatitis

Contact Dermatitis, a common skin condition, results from an adverse reaction to substances that come into direct contact with the skin. It leads to itchy, red, and inflamed skin, often resembling a rash. It usually localizes to body areas that have made contact with the irritant, such as the hands, neck, or face. While uncomfortable, it typically isn't life-threatening or contagious.

A form of cancer that primarily affects the skin

Cutaneous T-Cell Lymphoma

Cutaneous T-cell lymphoma (CTCL) is a class of non-Hodgkin lymphoma, which is a type of cancer of the immune system. Unlike most non-Hodgkin lymphomas (which are generally B-cell related), CTCL is caused by an abnormality in T-cells, a type of white blood cell. These abnormal cells proliferate in the skin, causing various manifestations, including rashes, tumours and lesions. If left untreated, it can progress to other parts of the body including the lymph nodes, blood, and internal organs.

A chronic skin condition causing small, deep-seated blisters on the hands and feet

Dyshidrotic Eczema

Dyshidrotic Eczema (also known as Pompholyx) is a condition that causes tiny, fluid-filled blisters to form on your fingers, toes, palms, and soles. It is episodic, displaying flares that can last for several weeks before easing. Repeated episodes can lead to flaky, cracked skin. It's not contagious but can cause substantial discomfort or even pain.

The early skin sign of Lyme disease, known for its characteristic 'bullseye' appearance.

Erythema Migrans

Erythema migrans (EM) is the earliest and most prominent symptom of Lyme disease, an illness caused by bacteria carried by ticks. This dermatological condition presents as a circular, red skin rash often described as looking like a 'bullseye' due to its pattern of fading from the center outward. EM usually appears about a week after a tick bite, but timing may vary. Without prompt and appropriate treatment, Lyme disease and its associated rash can lead to serious health problems affecting the joints, heart, and nervous system.

A reaction causing red, often itchy spots on the skin

Erythema Multiforme

Erythema Multiforme (EM) is a skin condition that manifests as a hypersensitive reaction to certain triggers, often infections or medications. It is characterised by red, target-like spots or circular patches that converge in the form of a rash. Interestingly, EM tends to occur mainly in children and young adults although it can appear in any age. It's not contagious, but it's necessary to treat the underlying cause.

A mild viral illness causing a facial rash

Fifth Disease

Fifth disease, also known as 'slapped cheek syndrome', is a mild, common viral illness that often affects children. It is known for the upper body rash that appears after a short period of mild illness. In contrast to many skin conditions, Fifth disease generally resolves on its own and rarely causes complications.

Irritating skin condition caused by bites from fleas

Flea Bites

Flea bites are small, red bumps that are the result of being bitten by fleas, which are tiny insects. They are commonly found on the ankles and lower legs but can occur anywhere on the body. Flea bites are typically noted for their red halo around a central spot and severe itchiness. While generally not serious, scratching flea bites excessively can lead to secondary infections that require medical attention. Flea bites are common among those who have pets at home or spend time with animals known to have fleas.

An inflammation of the hair follicles causing redness, swellings, and small, often pus-filled bumps

Folliculitis

Folliculitis is a fairly common, yet mostly harmless, skin condition caused by inflammation or infection of the hair follicles - the tiny pores on the skin from where hair grows. It manifests as red and swollen areas, often pimple-like bumps, around the follicles. Each bump may have a small dot at the center, representing the hair in the follicle. These bumps can appear anywhere on the skin that has hair, but they're most commonly seen on the arms, legs, buttocks, and face. Most cases of Folliculitis are easily manageable and go away without needing medical treatment.

A sexually transmitted viral infection causing recurrent genital sores

Genital Herpes

Genital Herpes is a common sexually transmitted disease where the herpes simplex virus (HSV) infects the area around the genital region or mouth. It is mostly asymptomatic, meaning you may not experience any symptoms, although you can still transmit the virus. When symptoms occur, they typically present as blisters and sores around the genital area or rectum. The infection can have outbreaks that come and go over time, but the virus remains in your body for life. It's essential to understand that even without symptoms, you can still pass on the disease to your sexual partners.

A common sexually transmitted infection caused by Human Papillomavirus (HPV)

Genital Warts

Genital warts are a sexually transmitted infection (STI) that appear as small, fleshy growths in the genital or anal areas. They're caused by the Human Papillomavirus (HPV), which has many different strains. Some can cause health problems like genital warts and cancers. However, vaccinations can help protect you from the most dangerous types of HPV. Though slightly discomforting, they are generally not painful and can be treated by a healthcare professional.

A benign skin condition that presents as ring-shaped patches on the skin

Granuloma Annulare

Granuloma Annulare (GA) is a benign (non-cancerous) skin condition that appears as small, firm bumps (nodules) that are usually arranged in a circular or ring-like pattern, often on hands, feet, or forearms. It is not contagious or dangerous, but it may cause discomfort or cosmetic concern depending on its location and extent. The condition can resolve on its own, but in some cases, it may last for several years.

A common viral illness that mostly affects infants and children

Hand Foot and Mouth Disease

Hand Foot and Mouth Disease (HFMD) is an infectious condition, usually mild in nature, that originates from certain strains of viruses. Typically, this condition largely impacts children under the age of 5 but it can still affect any age group. HFMD is characterized by a rash on the hands and feet, alongside sores in the mouth. It usually is resolved on its own within a week to ten days, but sometimes may require treatment to manage discomfort.

A common and mild skin irritation caused by excessive sweating in hot and humid weather

Heat Rash (Miliaria)

Heat rash, also known as prickly heat or miliaria, is a skin condition that arises when the sweat ducts get blocked and sweat can't escape through them to the skin's surface. It is usually caused by exposure to high heat and humidity. This condition is more common in babies and young children but can affect people of all ages. Heat rash consists of tiny blisters or bumps that feel prickly or intensely itchy. Although it might be uncomfortable, it is usually harmless and often clears up without medical intervention.

A chronic skin condition causing inflamed, painful lumps and abscesses

Hidradenitis Suppurativa

Hidradenitis Suppurativa (HS) is a long-term, or chronic, skin condition characterized by areas of inflammation, painful bumps or lumps, and possible abscesses mainly occurring where skin rubs together, such as the armpits, groin, buttocks, and under the breasts. This condition tends to start around puberty but can become worse over time. HS is more common in women and those with a family history of the condition.

A skin condition characterized by red, swollen bumps or welts that appear suddenly

Hives

Hives, also known as urticaria, are red or white raised areas on the skin that are often itchy. They can appear anywhere on the body, varying in size and shape, often changing within hours. Most cases of hives are acute, lasting less than six weeks. Chronic hives last longer than six weeks and may be a sign of an underlying health condition. Hives can be uncomfortable, but they are usually harmless and often clear up on their own.

A parasitic infection that causes skin and intestinal problems

Hookworm

Hookworm is a type of parasitic worm that primarily infects the intestines but its larvae can penetrate the skin. They are often transmitted through contaminated soil in areas with poor sanitation. In most cases, hookworm infections are not serious. However, they can lead to iron deficiency anemia and protein malnutrition, especially in children and pregnant women. Treatment includes anthelmintic medicines and iron supplements.

An inherited skin condition causing dry, scaly skin

Ichthyosis Vulgaris

Ichthyosis Vulgaris is the most common form of inherited skin disorder, affecting 1 in 250 people. The condition causes the outer layer of skin to become thick, dry and scaly, resembling fish scales. While it can be uncomfortable and cosmetically unpleasing, it typically isn't life threatening or contagious.

A highly contagious skin infection causing sores and blisters.

Impetigo

Impetigo is an infection of the skin caused by bacteria, typically Staphylococcus aureus or Streptococcus pyogenes. It's more commonly seen in children, but can affect people of all ages. Small sores and blisters form, which then ooze and crust over, forming a golden crust. Impetigo can be uncomfortable, and scratching can spread the infection to other areas. Antibiotics are the primary treatment and early treatment may prevent complications like cellulitis or kidney inflammation.

A common, harmless skin condition causing small, rough bumps, often on arms and legs

Keratosis Pilaris

Keratosis pilaris is a widespread, benign skin condition that presents as tiny bumps on the skin, resembling goosebumps or chicken skin. While it's found frequently in children, it can occur at any age. These bumps typically appear on upper arms, thighs, buttocks or face. Regardless of its somewhat aggravating nature, it's completely harmless and does not lead to any serious health problems. It's largely considered a cosmetic issue rather than a medical one. The condition tends to worsen in dry weather and may improve or even disappear completely during the summer months or in more humid climates.

An inflammatory condition that can affect the skin, hair, nails, and mucous membranes

Lichen Planus

Lichen Planus is a non-contagious inflammatory skin condition that primarily affects adults. It presents as small, flat-topped, polygonal bumps that are often itchy. While they can appear anywhere, they most commonly manifest on the inner wrists, forearms, and ankles. These bumps are usually purplish in color but can occasionally be pink or white. Other areas such as the scalp, nails, mucous membranes in the mouth or genitals might also be affected. While uncomfortable and sometimes unsightly, Lichen Planus is usually not a serious condition. However, because its symptoms are similar to other skin problems, it's important to get a proper diagnosis for appropriate treatment.

A type of skin cancer that can spread to other parts of the body

Melanoma

Melanoma is a serious form of skin cancer that begins in cells known as melanocytes. While it is less common than some other types of skin cancer, melanoma can spread (metastasize) to other parts of the body, making it more dangerous. While melanoma can be life-threatening, if detected early, it is often treatable with a good prognosis.

A common pigmentation disorder often referred to as the 'pregnancy mask'

Melasma

Melasma is a common pigmentation disorder that causes dark, discolored patches on your skin. It's most commonly seen on the face (cheeks, bridge of nose, forehead, and upper lip), but can appear on other parts of the body that get lots of sun exposure, like the forearms and neck. It's much more common in women than men, especially during pregnancy, hence the common term 'pregnancy mask'. Melasma does not cause any physical ailments but can affect your self-esteem and confidence due to its conspicuous nature.

Small, dark growths on the skin often appearing during childhood and adolescence.

Mole

A mole, medically referred to as a nevus, is a common skin growth often appearing as small, dark brown spots. Moles are caused by clusters of pigmented cells (melanocytes) presenting on the skin surface. While they generally appear during childhood and adolescence, they may change in color, size, and shape over time and with exposure to sunlight. Although most moles are benign, some can become cancerous and transform into a melanoma, a serious form of skin cancer.

A common, benign viral infection causing small skin bumps

Molluscum Contagiosum

Molluscum Contagiosum is a skin infection caused by the molluscum contagiosum virus that results in raised, firm, skin-colored or pearly bumps, usually less than 1 centimeter in diameter with a small indentation (dimple) in the middle. It's common among children and people with weakened immune systems. It spreads easily through direct skin-to-skin contact and by touching contaminated objects. Though it often resolves on its own without treatment in healthy individuals, it may require medical intervention in cases of a weakened immune system.

A chronic skin condition characterized by coin-shaped spots on the skin

Nummular Dermatitis

Nummular Dermatitis is a long-term skin condition that presents itself as distinctive coin-shaped (hence the term 'nummular') patches of red, itchy, scaly, or crusted skin. While, these patches can occur anywhere on the body, they are most often observed on the legs, hands, arms, and torso. This condition, which is also known as discoid eczema, is not contagious. It occurs more commonly in men than women and is more likely to appear in colder, dryer climates.

A common skin rash often resembling acne, mainly appearing around the mouth

Perioral Dermatitis

Perioral Dermatitis is a facial rash that tends to occur around the mouth. It might also appear on the nose, eyes, or forehead. The symptoms usually resemble a mix of acne and rosacea, with small red, bumpy spots or patches of red skin. This non-contagious condition is most common in young women but can affect anyone, including children.

A common, benign skin condition known for distinct rash patterns

Pityriasis Rosea

Pityriasis Rosea is a generally benign and common skin disorder characterized by a rash. The rash often starts with a single, larger 'herald patch' and is followed by smaller rashes that trail down the back, chest, and limbs in a 'Christmas tree-like' pattern. The condition is most common in individuals between the ages of 10 and 35, but it can affect anyone. Typically, Pityriasis Rosea resolves on its own within 6-8 weeks without treatment, but certain measures can be taken to alleviate symptoms like itchiness.

A highly irritating skin rash caused by exposure to plants like poison ivy

Poison Ivy Rash

Poison Ivy Rash (Toxicodendron Contact Dermatitis) is an allergic reaction that occurs when skin comes into contact with the poison ivy plant, or with touches something that has touched the plant. The rash is not contagious, but can be very bothersome as it itches a lot and can be painful. It typically appears 12 to 48 hours after exposure and can last up to 3 weeks if not treated correctly.

A recurring autoimmune disease causing red, itchy, and scaly patches on the skin

Psoriasis

Psoriasis is a persistent, long-term autoimmune disease that manifests in the skin. It causes your body's immune system to send out flawed signals that encourage skin cells to grow too quickly. New skin cells form in days rather than weeks, which results in bumpy red patches covered with white scales. These patches may cause discomfort ranging from itchiness to severe burning. Psoriasis isn't contagious—you can't spread it to others.

A common fungal infection causing a ring-shaped rash

Ringworm

Ringworm, not actually caused by a worm but a fungus, is a common skin condition that can affect anyone at any age. The infection presents as a ring-shaped rash, often itchy, and can appear almost anywhere on the body. It's known in the medical community as 'tinea' and can have different names depending on where it appears on the body such as 'athlete's foot' or 'jock itch'. Easily treatable in most cases, ringworm can be stubborn if left untreated, and may require a doctor's intervention.

A chronic, inflammatory skin condition causing redness and visible blood vessels in your face

Rosacea

Rosacea is a long-term skin condition primarily affecting the face, resulting in redness, swelling, and small, dilated blood vessels often accompanied by pimple-like blemishes. It frequently begins as a tendency to blush or flush more easily than most. It usually starts between the ages of 30 to 50 and is more common in those with fair skin. Rosacea's exact cause is ambiguous, but it could be a combination of genetic and environmental factors. Although it doesn't have a cure, treatments can control and reduce its signs and symptoms.

A highly contagious skin infestation caused by a tiny mite

Scabies

Scabies is a skin infestation caused by a mite known as the 'Sarcoptes scabiei'. These tiny eight-legged bugs penetrate the top layer of your skin to live and lay eggs, which leads to itching and rash. Scabies is found worldwide and affects people of every race and social class. It can spread quickly under crowded conditions where close body contact is frequent such as nursing homes and child care centers. It's not typically a severe condition, but it does need treatment to get rid of the mites.

A common and chronic skin condition that causes scaly, itchy patches, and red skin.

Seborrhoeic Dermatitis

Seborrheic dermatitis is a skin condition that primarily affects the sebaceous gland-rich areas of the skin, causing flaky scales, redness, and itching. Even though it's a long-term, or chronic disorder, its symptoms can be successfully managed with treatment. The condition is neither harmful nor contagious, but it can be uncomfortable and may impact self-esteem.

A common, harmless skin growth that appears in adulthood

Seborrhoeic Keratosis

Seborrheic keratosis is a non-cancerous (benign) skin growth that originates from cells in the outer layer of the skin. They may look worrisome as they often appear in multiples and have a wart-like surface, but they pose no threat to your health. These growths tend to appear in middle age or older and are common in adults over 50.

A painful, blistering skin rash caused by the varicella-zoster virus

Shingles (Herpes Zoster)

Shingles, also known as herpes zoster, is a viral infection that causes a painful rash. It typically affects one side of the body, often in a single stripe of blisters. The rash can occur anywhere, but most often appears on the torso. Shingles is also associated with intense pain that may continue after the rash has cleared, a condition called postherpetic neuralgia. Shingles is caused by the same virus that causes chickenpox. After having chickenpox, the virus remains dormant in your body and can reactivate years or decades later, causing shingles.

A common form of skin cancer that appears as abnormal, accelerated growth of squamous cells

Squamous Cell Carcinoma

Squamous Cell Carcinoma (SCC) is the second most common type of skin cancer, typically resulting from cumulative UV exposure over the years. Known for its capacity to spread to tissues, bones, and nearby lymph nodes, SCC can cause significant discomfort and potentially lead to life-threatening complications. Early detection is key to successful treatment with less serious outcomes.

Commonly known as Athlete's Foot, a contagious fungal infection affecting the skin on the feet

Tinea Pedis

Tinea Pedis, or Athlete's Foot, is a common skin condition caused by various types of fungi, primarily Trichophyton. This infection typically affects the skin on your feet but can spread to hands and other body parts. The condition is known for its itching, scaling, redness, and blistering symptoms. While it can be annoying, it's typically not serious and can be treated with over-the-counter remedies. However, for individuals with weakened immune systems, complications can arise requiring medical treatment.

A common fungal infection that disrupts skin pigmentation

Tinea Versicolor

Tinea versicolor, also known as pityriasis versicolor, is a common fungal infection that affects the skin's pigmentation, resulting in small, scale-like patches. These patches can be lighter or darker than your normal skin tone and usually affect the trunk and shoulders. Although Tinea versicolor can be distressing due to its effect on your appearance, it's essentially harmless and not contagious. Even though the condition responds to treatment, it often recurs.

A long-term skin condition characterized by patches of skin losing their pigment

Vitiligo

Vitiligo is a skin disorder where white patches of skin appear on different parts of the body due to the loss of melanocytes, the cells responsible for producing skin pigment. It can affect any area of your skin, but commonly appears on exposed areas, such as the face, hands, and feet. The white patches are usually permanent, but treatments can slow or halt the progression of the disease. While it's a physical condition, vitiligo can be emotionally challenging, affecting self-esteem and outlook. Remember, the appearance of your skin doesn't define you - stay strong, seek support, and consider reaching out to counselors or psychologists to help manage any emotional stress with it.

Small, rough and hard growths on the skin

Warts

Warts are common growths that appear on the skin due to the human papillomavirus (HPV). They are non-cancerous and often harmless, albeit they can be uncomfortable and visually unappealing. They can pop up anywhere on the body but are most commonly found on hands, feet, and the face. There are many types of warts, ranging from plantar warts often found on the feet to genital warts which occur on the sexual organs.
