Acne vulgaris:Acne vulgaris is the formation of comedones, papules, pustules, nodules, and/or cysts as a result of obstruction and inflammation of pilosebaceous units (hair follicles and their accompanying sebaceous gland). Acne develops on the face and upper trunk. It most often affects adolescents. Diagnosis is by examination. Treatment, based on severity, can involve a variety of topical and systemic agents directed at reducing sebum production, comedone formation, inflammation, and bacterial counts and at normalizing keratinization.
Atopic dermatitis:Atopic dermatitis, also known as eczema, is an itchy inflammation of the skin. It is a chronic disease that affects the integumentary system.

Hidradenitis suppurativa:Hidradenitis Suppurativa (HS), is a chronic, non-contagious, painful and quality of life impacting skin disease that causes boils to form in the folds of the skin and has a profound impact on quality of life.
Psoriasis:Psoriasis is an immune-mediated disease that causes raised, red, scaly patches to appear on the skin. While scientists do not know what exactly causes psoriasis, we do know that the immune system and genetics play major roles in its development. Usually, something triggers psoriasis to flare. The skin cells in people with psoriasis grow at an abnormally fast rate, which causes the buildup of psoriasis lesions.
