Have you ever found yourself pondering the intricate relationship between serums and moisturizers in your nightly skincare regimen? Specifically, is it truly beneficial to apply moisturizer following the application of a serum? Consider the implications of layering these products on the skin’s surface. Are there particular ingredients in the serum that might necessitate the sealing qualities of a moisturizer? Or could applying moisturizer after serum potentially impede the absorption of those potent serum ingredients? As night descends, when the skin’s repair mechanisms are most active, does this routine enhance or hinder that restorative process? Additionally, for individuals with varying skin types, does this practice yield different results? Could those with oily skin benefit less from this layering technique, while those with dry skin might find it indispensable? What does current dermatological research suggest about the effectiveness of this combination in achieving optimal hydration and skin health?
