What to apply after serum at night?

After applying serum at night, you should typically apply a hydrating face oil, followed by a moisturizer or overnight mask.

Here's a more detailed breakdown:

Nighttime Skincare Routine Steps

Cleanser: Begin with a clean base.
Toner (Optional): Balances the skin's pH.
Serum: Delivers concentrated active ingredients.
Hydrating Face Oil: Locks in the serum's benefits and provides nourishment.
Moisturizer/Night Cream/Overnight Mask: Provides a final layer of hydration and protection.

Serum First: Serums are lightweight and designed to penetrate the skin deeply. Applying them first ensures maximum absorption of their active ingredients.
Oil Next: Face oils are occlusive, meaning they create a barrier on the skin's surface. This helps to trap the serum's ingredients and prevent moisture loss. They also provide essential fatty acids and antioxidants.
Moisturizer/Mask Last: Moisturizers and masks are typically heavier and provide a final layer of hydration and protection. They work best when applied after the oil, as they can effectively seal in all the previous layers. A night mask provides a more intensive treatment while you sleep.

Hydrating Face Oils: Look for oils like rosehip oil, argan oil, jojoba oil, or squalane oil. These are generally well-tolerated and provide excellent hydration.
Moisturizers: Choose a moisturizer that is appropriate for your skin type (e.g., lightweight for oily skin, richer for dry skin).
Overnight Masks: These are designed to be left on overnight and provide a more intensive treatment than a regular moisturizer.

Skin Type: If you have oily skin, you may be able to skip the face oil and go straight to a lightweight moisturizer. If you have very dry skin, you may need to use a richer oil and moisturizer.
Product Formulation: Some serums already contain hydrating ingredients, so you may not need a separate face oil.
Listen to Your Skin: Pay attention to how your skin feels after each product application. If your skin feels greasy or congested, you may need to adjust your routine.
Patch Test: Always patch test new products before applying them to your entire face, especially if you have sensitive skin.
