What is "GLYCERYL ASCORBATE" and what does it do?

Role: HUMECTANT

Family: VITAMIN C Derivative

Comedogenic index: 0

Glyceryl ascorbate is a form derived from vitamin C, combined with glycerine for greater stability and efficacy in cosmetics.

Features and benefits
Stability and formulation: More stable than pure ascorbic acid, it offers greater formulation flexibility.
Skin tone improvement: Helps reduce dark spots and even out skin tone.
Cutaneous penetration: Excellent skin penetration capacity, facilitating efficacy.
Antioxidant effectiveness
Antioxidant power: Although effective, it is considered less potent than pure ascorbic acid.
Comparison with Ascorbic Acid: Less stable to light and air, but offers better molecular stability.
Dermatological properties
Improved Hydration and Firmness: Contributes to ceramide synthesis, reinforcing the skin's barrier and firmness.
Effective on Pigmentation Spots: Helps reduce hyperpigmentation and post-inflammatory marques.
Concentration and Efficiency
Concentration range: Used in concentrations of 1 to 10% in skin care products.
Concentration comparison with Pure Vitamin C: The studies do not specify the concentrations needed to obtain results comparable to those of pure vitamin C.

Glyceryl Ascorbate is a water-soluble variant of vitamin C. It is produced by linking ascorbic acid, the pure form of vitamin C, to glycerin, a humectant. Compared with ascorbic acid, this combination is more stable, while retaining many of the benefits associated with vitamin C.

Although Glyceryl Ascorbate and its derivatives are excellent antioxidants, they are considered less powerful than pure ascorbic acid, which is paradoxically less stable to light and air. This difference is explained by the molecular modifications required to create vitamin C derivatives. There therefore seems to be a balance between greater stability and slightly reduced antioxidant potential.
