Understanding Sensitive Skin
Understanding Sensitive Skin — skin that reacts easily with stinging, burning, redness, itching or tightness in response to products, environment or friction. Sensitivity can be an inherent trait or a temporary state caused by a compromised barrier.
Key points
- Common triggers include fragrance, essential oils, high-strength actives, physical scrubs, hot water and abrupt weather changes.
- A weakened skin barrier is the mechanism behind much reactive, easily-irritated skin.
- Patch-testing new products and introducing actives slowly (one at a time) reduces flare-ups.
- Look for short ingredient lists, fragrance-free formulas and soothing agents such as niacinamide, panthenol, centella and oat.
Frequently asked
Is sensitive skin a skin type?
It can be an inherent trait, but sensitivity is better understood as a separate axis: oily, dry or combination skin can each be sensitive, often due to barrier impairment.
What ingredients should sensitive skin avoid?
Common culprits are added fragrance, essential oils, high-percentage acids/retinoids used too often, and abrasive physical exfoliants; introduce anything new gradually.
