Serum should be applied before moisturizer. This is because serums are generally thinner and contain higher concentrations of active ingredients designed to penetrate the skin more deeply. Applying serum first allows these beneficial ingredients to be absorbed effectively. The moisturizer then acts as a sealant, locking in the serum and providing additional hydration.
Why Serum First?
Multiple sources confirm this approach:
-
Enhanced Penetration: Serums, with their lighter consistency, penetrate the skin more effectively when applied before a thicker moisturizer. This ensures optimal delivery of active ingredients like vitamins, antioxidants, and acids. (Medical News Today, Colorescience, Danielle Gervino)
-
Ingredient Efficacy: Applying serum before moisturizer maximizes the effectiveness of the serum's active ingredients. A moisturizer applied first could block the serum's absorption. (Reddit - Skincare Addiction)
-
Optimal Hydration: The moisturizer acts as a final step, sealing in the serum and providing an additional layer of hydration. (Reddit - Makeup)
Application Process:
- Cleanse: Begin with a clean face.
- Serum: Apply a few drops of serum to your face and neck, gently patting it in.
- Wait: Allow the serum to absorb for a minute or so.
- Moisturizer: Apply your moisturizer, gently massaging it into your skin.
Note: Always check the product labels for specific instructions. The optimal order may depend on the specific ingredients and formulations of your products.
