Summary

Humectant Skin Conditioning Collagen Booster Elastin Booster Antioxidant Skin Barrier Support Anti-aging Anti-wrinkle

Science

Mechanism of Action

This ingredient operates by elevating cellular activity within the skin, directly stimulating the endogenous production of collagen and elastin. It offers protective benefits by inhibiting enzymes like collagenase and elastase, mitigating degradation induced by UV radiation and inflammation. Furthermore, it functions as a humectant, drawing moisture into the skin to fortify the natural barrier, and acts as a potent antioxidant, neutralizing free radicals and supporting robust dermal fibroblast activity and keratinocyte differentiation.

Stability

While raw eggshell membrane is water-insoluble, hydrolysis (e.g., alkaline at 70-100 °C or enzymatic at pH 6-8, 40-60 °C) renders it water-soluble. Specific optimal pH ranges for the stability of the final hydrolyzed ingredient in cosmetic formulations are not available in the provided data.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

Although Hydrolyzed Egg Shell Membrane has not been individually reviewed by the CIR Expert Panel, related skin and connective tissue-derived proteins and peptides (including Hydrolyzed Collagen) have been deemed safe for cosmetic use. A specific partially-hydrolyzed eggshell membrane powder (NEM®) holds GRAS status from the FDA for oral consumption up to 500 mg per serving. In topical applications, it is generally recognized as non-irritating, with 'Egg Shell Membrane Extract' being categorized as 'SkinSAFE 100 Free,' 'Irritant Free,' 'Fragrance Free,' and 'Paraben Free,' supporting its favorable safety profile for sensitive skin.
