Science

Mechanism of Action

HYDROXYSTEARIC/LINOLENIC/LINOLEIC POLYGLYCERIDES operates by mimicking the skin's native barrier lipids, thereby strengthening skin integrity and reducing moisture loss. Its composition includes linolenic acid, an omega-3 fatty acid offering antioxidant and reparative benefits, and linoleic acid, an omega-6 fatty acid crucial for barrier repair, sebum regulation, and a potential reduction in hyperpigmentation by influencing melanin desquamation. Hydroxystearic acid provides additional emollience and contributes to formula stability.

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed the individual fatty acid components, deeming Hydroxystearic Acid and Linoleic Acid safe under current cosmetic use practices when formulated to be non-irritating and non-sensitizing. Although the specific polyglyceride blend has not been separately reviewed by CIR, SCCS, or FDA, it is widely considered skin-friendly, exhibits excellent skin tolerance, and holds certifications from natural and organic cosmetic bodies like COSMOS and NATRUE. A related polyglyceride blend (Hydroxystearic/Linolenic/Oleic Polyglycerides) is rated 'LOW' by EWG Skin Deep for various toxicity concerns.
