    • Purified oat extract: A refined, skin-nourishing complex, oat extract helps calm skin, diminish the appearance of puffiness, redness, and irritation while helping reveal a more uniform and healthy-looking complexion.
    • Shea Butter: Deeply hydrating, shea butter forms a breathable shield atop skin to lock in moisture and keep toxins out. Rich in Vitamins A, D, and E, shea butter delivers emollient and antioxidant properties to visibly soften, tone, and smooth the skin.
    • Peptides: Naturally present in the body, peptides encourage the flow of water between skin layers and encourage skin turnover for improved collagen, firmness, and circulation.
    • Avocado Oil: Rich in antioxidants, vitamins, and nutrients, avocado oil conditions the skin's appearance and deeply hydrates.
    • Grapeseed Oil: Rich in oleic and linoleic acid, Vitamin E and nutrient-rich polyphenols, grapeseed oil defends skin from environmental aggressors and leaves skin feeling silky-soft to the touch.
    • Organic Argan Oil: Rich in vitamin E, fatty acids, and antioxidants, argan oil helps soften and nourish skin, plus defend against environmental aggressors and support the skin's moisture barrier.
