Squalane and Oat SerumFor skin that reacts to everything: no fragrance, no preservatives, no additives of any kind. For skin and scalp with hypersensitivity to oils, Squalane is one of the few lipids that does not trigger a reactive response. Squalane as an ingredient is well studied for its compatibility with eczema, rosacea, and psoriasis prone skin, including the scalp, where the skins lipid barrier is typically compromised and highly reactive to foreign ingredients.
