Science
Mechanism of Action
This extract functions by upregulating Hyaluronic Acid Synthase-2 (HAS2), leading to a measurable increase in skin stratum corneum moisture. Its unique peptide profile effectively scavenges over 75% of free radicals and activates Nrf2-ARE pathways, bolstering intrinsic cellular antioxidant defenses. Proline-hydroxyproline dipeptides stimulate fibroblast activity, resulting in a 2.3-fold increase in type I collagen mRNA levels, while specific elastin peptide segments activate TLR4 receptors, promoting dermal elastic fiber regeneration. Furthermore, it downregulates NF-κB signaling pathways, reducing pro-inflammatory factors TNF-α and IL-1β expression by 40%-60%, and exhibits anti-collagenase and anti-elastase activities to preserve skin integrity.

Key findings
- 01 Topical application of 5% water-soluble eggshell membrane (BiovaDerm) resulted in an average reduction in wrinkles of 34.21% at four weeks.
- 02 Increasing topical concentration to 10% (BiovaDerm) further enhanced wrinkle reduction, showing an average of 48.09% at four weeks.
- 03 An 8-week pilot study evaluated an 8% topical formulation (BiovaDerm) for wrinkle reduction and elucidated specific mechanisms of action.
- 04 Oral intake over 8 weeks led to a 31% increase in skin stratum corneum moisture and a 19% reduction in transdermal water loss, correlating with HAS2 upregulation.
- 05 Oral ingestion of 450 mg/d of hydrolyzed eggshell membrane significantly improved facial crow's feet in 4 weeks and skin tone in 8 weeks.

Formulation
Stability
For cosmetic applications, the extract solution demonstrates optimal stability when neutralized to a pH range of 7.2-7.4. While initial extraction methods may involve higher alkaline pH levels (e.g., pH 8.0 or higher, preferably pH 11-12) for protein solubilization, this refers to processing and not the stability of the final ingredient within a product.
Safety
Safety Profile
Egg Shell Membrane Extract has not undergone explicit review by CIR or SCCS for cosmetic use. However, an egg membrane ingredient received a 'not anticipated to pose any risk to human health' assessment for Novel Food status in the EU as a food supplement. Comprehensive testing for pesticides, antibiotics, and dioxins has been conducted for food supplement applications. SkinSAFE classifies this ingredient as 'SkinSAFE 100 Free', 'Irritant Free', 'Teen SAFE', 'Lip Safe', 'Baby Safe', 'Eyelid SAFE', 'Fragrance Free', and 'Paraben Free', indicating a high safety profile, particularly for sensitive skin.
