The number one most common skin condition is Acne, affecting teens and adults with clogged pores, oil, and bacteria, leading to pimples, blackheads, or cysts.

Autoimmune skin diseases cannot be cured, but we can help manage flare ups with treatment.
Hidradenitis suppurativa (HS) is a painful, long-term skin condition that causes skin abscesses and scarring on the skin. The exact cause of hidradenitis suppurativa is unknown, but it occurs near hair follicles where there are sweat glands, usually around the groin, bottom, breasts and armpits.
Because oily skin is a little harder to treat due to its origins in hormones, stress levels, and genetics, it can be a little harder to treat than dry skin. However, it can still be treated and maintained through the right routine. Wash oily skin every morning and evening, and additionally after exercise.
The white patches caused by vitiligo are usually permanent, although treatment options are available to reduce their appearance. If the patches are relatively small, skin camouflage cream can be used to cover them up.

Melanoma is the deadliest and most preventable skin disease.
High school (secondary education)
The most excruciating part is that the pain is long-term, and likely to be for life. In fact, CRPS is known as the world's most painful incurable condition.

1. Necrotising fasciitis.

The infection is rapid, fast-spreading and fatal if not detected and treated early.
Epidermolysis bullosa (EB), sometimes called butterfly skin, is a group of rare skin diseases with a common symptom: fragile skin that tears and blisters easily. Children with this disease are sometimes called “butterfly children” because their skin is as delicate and fragile as a butterfly's wing.
Bacterial rashes often show acute signs like pus, rapid swelling, warmth, and pain, spreading quickly and treated with antibiotics (e.g., impetigo, cellulitis), while fungal rashes develop slowly in warm, moist areas, causing intense itching, redness, scaling, and distinct rings (like ringworm, athlete's foot), requiring antifungals and keeping the area dry. The key difference lies in appearance, location, speed, and treatment: bacteria cause rapid inflammation and need antibiotics; fungi cause itchy, scaly patches in damp spots and need antifungals.
Rashes might appear purple or brown on darker skin tones. A red rash that spreads across your cheeks and the bridge of your nose, in the shape of a butterfly (malar rash). Rashes might appear purple or brown on darker skin tones. Patches of lighter and darker pigment on your skin.
