About this ingredient
Homarine HCl (INCI: Homarine HCl) is an osmolyte that works as a humectant. Osmolytes help cells balance their water content, so in the skin they support water retention and ease the feeling of discomfort and tightness. It appears in creams, serums and formulas for sensitive or dehydrated skin. On efficacy it is a supporting hydrating and soothing active. It improves water retention and skin comfort, with a plausible mechanism, though independent evidence is still limited. It works well as part of a moisturizing system rather than as an isolated star active. For topical use it has no systemic relevance and can be used during pregnancy and breastfeeding. Tolerance is good: low irritation potential and low allergy risk, which makes it suitable for sensitive and reactive skin, which is exactly where it is most often used.
