Dermatology covers skin, hair and nails: moles and skin cancer, acne, eczema, athlete's foot and sun protection. We explain which skin changes are worrying, how moles are assessed and when to see a dermatologist. The content is for reference and does not replace a doctor's examination.
Ultraviolet radiation is invisible and cannot be felt, yet its effects can be both acute and chronic. We explain what the UV index means, which consequences are proven, and how to protect yourself.
A normal mole has an even edge and a single color. How to read ABCDE, what changes in melanoma, and when a spot should be shown to a doctor.
Acne is a chronic inflammation of the sebaceous glands, not a cosmetic defect. We explain the mechanism, the role of hormones, the types of breakouts, and the point at which skincare alone is no longer enough.
Atopic eczema is a chronic skin condition in which itching is the main symptom. What "atopy" means, which factors trigger flare-ups, and when to seek help.
Itching between the toes, peeling, a yellowed thickened nail — what foot and nail fungus looks like, where it is contracted, and how the diagnosis is confirmed with a scraping.
Psoriasis is a chronic non-infectious skin disease with scaly plaques. We explain the forms, triggers, the link to joints, and when to see a doctor.
