• Over-exfoliation during winter can strip the skin of natural oils, weakening its barrier. Limit exfoliation to once or twice a week and choose gentle chemical exfoliants.
• Overuse of retinoids and vitamin C can cause irritation. Reduce frequency and pair with hydrating ingredients like hyaluronic acid and ceramides.
• Dry winter air necessitates rich moisturizers with ingredients like shea butter, glycerin, and squalane to lock in moisture and protect the skin.
