Skin-Replenishing Ingredients



Skin-Replenishing Ingredients description

These are skincare ingredients that help enrich skin’s surface, drenching it with revitalising hydration and keeping it there. Doing so helps keep skin looking and feeling soft, smooth, and supple, especially skin that’s persistently dry, tight, and uncomfortable. Daily application of skin-replenishing ingredients keeps skin safeguarded from environmental factors that lead to moisture loss and dehydration, and help skin appear younger, more vibrant, and replenished. There are numerous skin-replenishing ingredients to consider, some of which are naturally present in skin, including hyaluronic acid, ceramides, sodium PCA, glycerine, glycerol, cholesterol, and phospholipids. Other examples of research-proven skin-replenishing ingredients are silicones, petrolatum, triglycerides, omega fatty acids, and exfoliating ingredients like alpha hydroxy acids (AHAs like glycolic acid) and beta hydroxy acid (BHA, salicylic acid).
