A moisturizer is a cosmetic product designed to increase skin hydration, reduce transepidermal water loss (TEWL), and support skin barrier function. They work by increasing water content within the stratum corneum while reinforcing the lipid matrix that helps retain moisture. Understanding how moisturizers perform can help you determine which are best for your skin. Â
When the barrier is functioning well, skin feels more comfortable, less reactive, and more resilient. Skin protectants are one of the tools available to support that process when reinforcement is needed: They are formulated with FDA-approved active ingredients designed to temporarily protect compromised skin and reduce moisture loss.
Alpha Arbutin helps reduce the look of uneven tone for a brighter looking complexion.
