Restorative ceramides + fatty acids + cholesterol rebuild barrier lipid integrity. Moisturize at a profound level. Epidermal lipids are an essential part of the skins stratum corneum. Therefore the most effective lipids for maintaining skin health are those most identical to the epidermal lipids; ceramides (50%), cholesterol (25%) and fatty acids (25%). These lipids also make up about 50% of cell membranes and can be damaged due to a process called lipid peroxidation, as well as exposure to internal and external stressors. Intercellular lipid damage compromises barrier function, which can lead to transepidermal water loss. TEWL can result in dryness, irritation, and wrinkles. It follows that lipids are an integral part of skin health and the key to a well-functioning barrier system. The essence of skin moisturizing is lipid replacement, best accomplished by applying the correct lipids in the proper ratios. Among the formulas benefits are: - Ceramides maintain youthful, plump, well-hydrated skin. - Cholesterol lubricates surface layers, delivering an emollient + creamy texture to moisturize profoundly, without risk of irritation or breakouts. - Biomemetic fatty acids balance skins oil ratio without essential oils to disrupt barrier lipid balance or threaten its microbiome. - 1 oz.
