You should generally apply moisturizer first, followed by sunscreen. This allows the moisturizer to fully absorb into your skin, creating a smooth base for the sunscreen to sit on. Think of it as wearing a sweater first, then putting on a coat for extra protection. Sunscreen acts as your skin's protective "coat" against harmful UV rays.
However, there are some exceptions:
- Chemical sunscreens: Applying chemical sunscreen before moisturizer allows it to penetrate your skin more effectively.
- Sunscreens with moisturizing properties: You may be able to skip the moisturizer altogether if your sunscreen already contains hydrating ingredients.
Ultimately, the best order depends on your specific skincare routine and the products you use.
