Sheet and hydrogel face masks are typically left on for 10–30 minutes (many brands recommend 10–20 or 15–30 minutes). Under-eye masks vary: some reusable silicone under-eye masks recommend 10–20 minutes, while certain silicone treatment masks are designed to be worn overnight.
Hydrogel under-eye patches provide direct hydration, can brighten tired-looking eyes, plump the under-eye area, and help minimize the appearance of fine lines. Reusable silicone under-eye masks are used over a serum or cream to create a seal that helps lock in ingredients and boost hydration; with repeated use they can also help smooth the look of fine lines.
Common scent options include lavender (lavender oil or lavender-filled inserts), aloe, peppermint, green tea, coconut, and unscented versions for those who prefer no fragrance.
