What causes facial redness
Persistent redness usually has one of four causes: a damaged skin barrier (from over-cleansing, exfoliation or actives), rosacea, contact irritation from fragrance or essential oils, or heat and sun. The first three respond to the same approach: stop the irritant, cleanse gently, calm and hydrate, protect from sun. Rosacea additionally benefits from medical treatment, so see a dermatologist if redness comes with visible vessels, bumps or flushing that lasts.
Ingredients that calm, with evidence
- Centella asiatica: reduces inflammatory signalling and supports repair; the basis of most "cica" products.
- Colloidal oatmeal: anti-itch avenanthramides; recognized by the FDA as a skin protectant.
- Niacinamide: strengthens the barrier and reduces redness at 2% to 5%.
- Aloe and cucumber in the cleanser: cooling and soothing while you wash.
What to avoid while skin is red
Hot water, physical scrubs, acids, retinoids, high-strength vitamin C, fragranced products and long hot showers. Reintroduce actives only after two calm weeks, one at a time. Nihon (gentle vitamin C) is usually the first that redness-prone skin tolerates; Kido and Izumi come later.
