As an esthetician, this is a question I get asked from time to time. The short, quick answer is no—it’s not necessarily “wrong,” but it's also not the best idea.
You’re Cheating Your Skin
Think about it: why use a sunscreen at night when your skin could benefit much, much more from a moisturizer that is formulated to use at night? Our skin is in repair mode while we sleep; enhance that process with a high quality night cream that is appropriate for your skin type. Night creams are typically more concentrated in formula and contain more emollients (ingredients that moisturize the skin). Take a peek at a few of our night creams... Seaweed Night Cream This oil-free formula is packed with nourishing ingredients such as Seaweed, Collagen and ultra-hydrating Hyaluronic Acid. Chamomile Night Cream Ideal for dry or sensitive skin, this night cream contains Vitamin A and soothing Chamomile Extract. Elasto-Collagen Night Cream For very dry or mature skin types, this formula is enriched with Collagen, Vitamins A and E, and beneficial oils such as Peanut and Carnation.
Although it’s not a skin crisis to use a moisturizer with sunscreen at night, why not treat your skin with the utmost care and use a night cream before bed instead?
