Undecylenoyl Glycine – Mechanism & Skin Benefits

Due to its structural similarity to naturally occurring lipoamino acids found in cellular protoplasm, Undecylenoyl Glycine has become a fundamental structural motif in cosmetic additives. The molecule combines two functional moieties: the glycine head provides essential biological activity, while the undecylenic acid long chain facilitates skin penetration.

Glycine (Gly) – Functional Contributions

1. Moisturizing Effect

Glycine is a constituent of the Natural Moisturizing Factor (NMF) in the stratum corneum and a major component of dermal structural proteins. Both roles are essential for skin hydration and make glycine an indispensable factor in the skin’s natural moisturizing system.

2. Anti-Wrinkle Effect

Glycine accounts for approximately 35% of the amino acid composition of dermal collagen, the primary structural protein of the dermis. Elastin, another key dermal structural protein that provides fundamental support to the dermis, also contains significant amounts of glycine.

3. pH Buffering Effect

Healthy skin maintains a slightly acidic pH, a fundamental property conferred by the lipid-protein rich surface layer. However, external environmental stressors frequently induce decarboxylation reactions in the skin, generating free ammonia (NH₃), which can cause substantial damage. Consequently, compromised skin typically exhibits a higher pH than normal skin.

This pH shift is primarily driven by dysbiosis of the skin’s surface microbial ecosystem, which disrupts the natural acid mantle. Therefore, providing a substance with mild acidic functional groups becomes essential. Such weakly acidic structures can normally store acidity and help restore the skin’s weakly acidic environment under adverse conditions. Following acylation of undecylenic acid with glycine, the carboxyl group of glycine remains free, enabling this buffering function effectively.
