Science
Mechanism of Action
Epigallocatechin Gallate (EGCG) functions as a robust antioxidant, actively mitigating oxidative stress from environmental factors. It exhibits anti-inflammatory, anti-acne, and anti-aging effects by enhancing skin hydration and elasticity through hyaluronic acid synthesis regulation, promoting collagen production, and inhibiting its degradation. Collagen acts as a topical humectant, binding moisture to the skin and providing structural support for improved elasticity. While Biotin is critical for cellular metabolism, its direct topical benefits are less comprehensively documented. Mouse Fibroblast Conditioned Media introduces a complex mixture of growth factors, cytokines, and proteins that stimulate cellular proliferation, aid in healing, and enhance the deposition of extracellular matrix components, supporting overall skin rejuvenation.

Key findings
- 01 Topical application of 0.5-1% EGCG has demonstrated benefits in skin hydration, anti-acne, antioxidant defense, anti-inflammatory action, and anti-aging effects.
- 02 A 2.5% w/w EGCG cream, applied twice daily for six weeks, reduced markers of angiogenesis (HIF-1α and VEGF) in human skin.
- 03 In cell studies, 100 μM EGCG significantly decreased extracellular melanin secretion without cytotoxicity, indicating potential skin brightening capabilities.
- 04 Treatment with 25 μM EGCG increased the expression of genes crucial for Natural Moisturizing Factor (NMF) synthesis, including filaggrin and hyaluronic acid synthases.

The Formula
Formulation
Stability
Epigallocatechin Gallate (EGCG) is susceptible to oxidation, particularly at alkaline pH, and degrades with heat exposure, necessitating acidic pH formulation and protection from high temperatures. It may benefit from co-formulation with penetration enhancers and other antioxidants to maintain stability and prevent pro-oxidant activity. Collagen remains generally stable in aqueous environments. Mouse Fibroblast Conditioned Media requires cold storage (≤ -20°C or -20 to -70°C), slow thawing, and strict avoidance of repeated freeze-thaw cycles to preserve its performance.
Synergies
- EGCG can be enhanced by co-formulation with other antioxidants to boost its stability and efficacy.
- Penetration enhancers may improve EGCG delivery into the skin.
Conflicts
- Strong oxidizing agents (EGCG)
- Alkaline pH (EGCG)
- Heat exposure (EGCG)
- Repeated freeze-thaw cycles (Mouse Fibroblast Conditioned Media)
Safety
Safety Profile
EGCG shows good safety up to 1% in dermal applications, with minimal toxicity to normal skin cells at effective concentrations. Biotin and topical Collagen are generally considered safe. However, the inclusion of Mouse Fibroblast Conditioned Media, containing potent growth factors, is subject to notable controversy in skincare. Regulatory bodies like the EWG categorize human fibroblast conditioned media as 'unacceptable' due to 'high use restrictions,' recommending caution for individuals with high skin cancer risk or psoriasis. This concern extends to fibroblast-derived growth factors irrespective of their animal or human origin. In the EU, human cell-derived ingredients are prohibited.

Verdict
While offering a compelling blend of benefits from EGCG, Collagen, and Biotin, the inclusion of Mouse Fibroblast Conditioned Media raises significant safety and regulatory concerns due to its growth factor content, categorizing this complex ingredient as questionable for broad use.
