What should you know about red flaky skin?

A recent product, detergent, plant, or metal contact may cause itchy, dry, inflamed patches. Sunburn tends to follow sun exposure and may feel hot or tender. Heat rash appears in warm, sweaty areas. Psoriasis often forms well-defined thicker scale, while rosacea commonly affects the central face with flushing. Infection becomes more concerning when redness is hot, painful, rapidly expanding, or paired with fever. Skin redness is a visible sign rather than a diagnosis, so location, timing, scale, and associated symptoms guide assessment.

Wash with lukewarm water and a mild fragrance-free cleanser, then apply a bland moisturiser while the skin is slightly damp. Stop suspected irritants and avoid scrubbing, peeling flakes, fragranced oils, and very hot water. Protect exposed areas from sunlight and heat. Do not use leftover antibiotics or strong steroid creams without advice, especially on the face. Take a clear photograph and note new products, outdoor exposure, sweating, itch, pain, and spread.

Get urgent medical help for rapidly spreading redness, severe pain, fever, pus, marked warmth, facial or eye swelling, or red streaking. Seek prompt advice for blistering, extensive peeling, or involvement of the eyes, mouth, or genitals. Arrange review when the rash persists, repeatedly returns, or does not improve after removing a suspected trigger.
