Mechanism of Action
Glycogen functions as an essential fuel for skin cells, rapidly converting to glucose to power metabolic activities and boost ATP production, thereby promoting enhanced cellular repair and regeneration. Its action supports optimal epidermal cell turnover, contributing to a smoother texture and improved elasticity. As a powerful humectant, glycogen attracts and binds water, significantly elevating hydration levels and strengthening the skin's natural barrier against trans-epidermal water loss. Moreover, it actively promotes ceramide synthesis by upregulating a-SMase activity, stimulates fibroblasts to produce collagen, elastin, and hyaluronic acid, and offers antioxidant protection against environmental pollutants. Glycogen also exhibits modulatory effects on inflammatory mediators, helping to reduce redness, calm irritation, alleviate sensitivity, and aid in preventing hyperpigmentation by supplying critical cellular energy.

Key findings
- 01 Enhanced skin hydration by 60% after 7 hours, and boosted hyaluronic acid moisturizing performance instantly and up to 40% after 7 hours (in vivo, 30 women).
- 02 Reduced crow's feet wrinkle area by 11% and depth by 5%, and 'line erasing' wrinkle area by 75% and depth by 20% (in vivo, 30 women).
- 03 Reinforced skin barrier function by 23%, reduced skin sensitivity by 38%, and increased skin hydration by 130%. Also reduced redness by up to 15%, increased skin radiance by up to 7%, and skin homogeneity by up to 7% (in vivo).
- 04 Increased skin hydration by an average of 45% (clinical trial, 30 individuals with dry skin).
- 05 Reduced crow's feet wrinkles by an average of 42% and forehead wrinkles by an average of 54.9% (non-independent study, 4 individuals with photoaging).
- 06 Improved pigmentation by an average of 30% (non-independent study, 30 volunteers with age spots).
- 07 Enhanced skin tone, reduced pigmentation area by up to 59%, resulting in 12% increased skin homogeneity, 12% reduced dullness, 56% more even skin tone, and 85% reduced hyperpigmentation intensity (in vivo).
- 08 Increased cellular growth rate, Type 1 collagen production, and hyaluronic acid production in human fibroblast cells (in vitro).
- 09 Enhanced cellular amount of ceramide NS (ceramide 2) by 3.4-fold in cultured keratinocytes (in vitro).

Safety
Safety Profile
Glycogen is widely regarded as safe for cosmetic use, primarily due to its natural presence within the human body and skin. There are no known restrictions on its concentration in cosmetic formulations, and no specific adverse opinions from CIR or SCCS have been identified. Any recalls associated with glycogen-containing products have been attributed to undisclosed drug ingredients, not the glycogen itself.
