Often, the importance of a healthy skin barrier only becomes apparent once it has been damaged: The increase in transepidermal water loss (TEWL) causes skin to look reddened, feel tight or sensitive, or develop impurities. This is the reason why barrier creams or barrier boosters have become so popular – they reduce redness and irritations or help to restructure the skin’s protective barrier layer. Active ingredients such as AvenaPlex from Oat Cosmetics, Idaskin from Codif oder SLVRCoffee™ from Mibelle Biochemistry are ideal for these kind of beauty products.
