Peaux sensibles sensitive skin: what to know

Sensitivity is a symptom pattern rather than one single diagnosis. The skin may react after cleansing, shaving, fragranced products, heat, cold, wind, sweat, or a cosmetic procedure. A weakened skin barrier can allow irritants to reach nerve endings more easily, causing burning or stinging even when there is little visible rash.

Ongoing redness, scaling, itch, facial flushing, or a rash around the mouth can point to a treatable condition such as atopic dermatitis, rosacea, or perioral dermatitis. The trigger, location, appearance, and duration help a clinician decide whether the problem is irritation, allergy, inflammation, or another cause.

Use lukewarm water, a mild fragrance-free cleanser, and a plain moisturiser. Introduce one new product at a time and test a small area first; stop if burning or swelling develops. Avoid scrubs, strong fragrances, frequent exfoliation, and very hot water while the skin is unsettled. Protect exposed skin from sunlight and wind, and rinse sweat gently rather than rubbing.

Keep notes about products, foods, weather, stress, shaving, and treatments that precede a flare. Do not repeatedly apply steroid cream to the face without medical guidance, especially around the mouth. A simple routine makes it easier to identify a trigger and judge whether the barrier is recovering.

Seek prompt advice for a rash that is spreading, painful, crusting, blistering, or producing fluid, or for symptoms that keep returning despite a gentle routine. Urgent help is needed for sudden facial or lip swelling, breathing difficulty, faintness, or widespread hives. Arrange a skin assessment when sensitivity interferes with sleep, work, washing, or the products needed for daily life.

Does my pattern fit irritation, allergy, rosacea, atopic dermatitis, or perioral dermatitis? Which cleanser and moisturiser should I use? Should I stop any current treatment, and for how long? Do I need patch testing or a prescription, and what symptoms should prompt an earlier review?
