What Makes an Overnight Moisturizer Effective
An overnight moisturizer works by forming a protective barrier that reduces water loss while you sleep. Thick creams and ointments with occlusive ingredients help lock in hydration. According to the American Academy of Dermatology, ingredients like petrolatum, dimethicone, and ceramides support the skin barrier and help prevent dryness overnight.
Key Ingredients to Look For
Look for humectants such as glycerin and hyaluronic acid, which draw moisture into the skin. Emollients like shea butter and squalane soften and smooth the surface. Occlusives such as petrolatum and beeswax reduce transepidermal water loss. These combinations help skin retain hydration through the night.
How to Choose the Right Product
Choose a fragrance-free formula if you have sensitive or eczema-prone skin. Thicker textures usually provide more occlusion, making them suitable for very dry areas. The National Eczema Association recommends simple formulations with minimal irritants for overnight use. Patch test new products on a small area before applying them to your full face.
Find dermatologist recommended moisturizers that match your skin type and concerns.
