What is the best practice regarding the application of moisturizer?

Applying moisturizer while the skin is still damp is considered the best practice because it enhances absorption. When skin is slightly moist, the barriers that can impede moisture penetration are reduced, allowing the active ingredients and hydrating agents in the moisturizer to penetrate more effectively. This technique helps to lock in water and hydration, preventing transepidermal water loss.

In contrast, applying to dry skin may not provide the same level of efficacy since the skin's ability to absorb hydration diminishes as it dries out. Using a large amount of moisturizer does not necessarily enhance its effectiveness; more isn’t always better, and applying too much can lead to product buildup or clogged pores. Lastly, applying moisturizer only once a day may not suffice for those with dry or dehydrated skin, as regular reapplication—especially after cleansing or exposure to environmental elements—can be key to maintaining optimal hydration levels throughout the day.
