Experts warn expired cosmetics can harbor bacteria and cause infections. Makeup and skincare degrade after opening due to air, light, and skin oils. Mascara is highest risk — replace every 3 months to avoid eye infections like conjunctivitis or styes. Sunscreen should be replaced each season (check expiry, heat exposure accelerates breakdown). Antioxidant serums (retinol, vitamin C) last 6–12 months after opening. Creamy, water-rich products (cream blush, some eyeshadows, open moisturizers) can breed bacteria — replace within 6–12 months. Makeup sponges should be replaced monthly even with regular washing. Liquid foundation and concealer: 6–12 months; oils (cleansing/body oils): 6–8 months due to oxidation. Lip products: 12–18 months unless contaminated (e.g., during a cold). Brushes: deep-clean weekly and replace every 1–2 years. Check travel-size samples after trips and discard or clean containers. Proper storage (avoid humid bathrooms, keep lids tight, clean organizers) and regular decluttering every 6 months help prevent contamination.
