While sleeping, you can incorporate products into your skincare routine that provide hydration, repair, and nourishment to your skin overnight. Here are some suggestions of what you can put on your face while sleeping:

1. Night Cream: Night creams are formulated to provide deep hydration and repair for your skin while you sleep. Look for a night cream with ingredients like hyaluronic acid, retinol, peptides, or ceramides for added benefits.

2. Serums: Serums with ingredients like vitamin C, niacinamide, or antioxidants can help brighten your skin, reduce signs of aging, or target specific skincare concerns. Apply a serum before your night cream for added benefits.

3. Facial Oils: Facial oils can help lock in moisture and nourish your skin overnight. Look for oils like jojoba, rosehip, or squalane that are non-comedogenic and suitable for your skin type.

4. Sleeping Masks: Sleeping masks are intensive overnight treatments that can provide hydration, brightening, or firming effects to your skin. Apply a sleeping mask as the final step in your nighttime routine.

Remember to cleanse your face before applying any products and tailor your skincare routine to address your specific concerns and skin type.
