Science
Mechanism of Action
MEP acts as a non-hormonal agonist, selectively engaging with ER-beta receptors located on skin cells. This interaction initiates a cascade of beneficial cellular processes, including stimulating the synthesis of collagen and elastin, augmenting dermal hydration, and significantly enhancing skin elasticity and firmness. Furthermore, MEP promotes skin thickness and integrity by fostering the growth of epidermal keratinocytes and fibroblasts, and can activate gene expression crucial for DNA repair and protection. Notably, MEP undergoes rapid metabolism into an inactive compound directly within the skin, ensuring its therapeutic effects are localized and preventing any systemic estrogenic activity.

The Formula
Formulation
Stability
Methyl Estradiolpropanoate, as a synthetic derivative, is engineered for inherent stability within diverse skincare formulations. It has been successfully incorporated into products such as serums and night creams.
Safety
Safety Profile
Methyl Estradiolpropanoate is widely described as a non-hormonal analog that ensures skin safety by metabolizing into an inactive compound localized within the skin, thereby precluding systemic estrogenic effects. While some studies noted potential adverse events like transient irritation or dryness, formulated products, such as an MEP-containing eye cream, were generally 'well tolerated'. There is currently no specific safety assessment published by the Cosmetic Ingredient Review (CIR) or the Scientific Committee on Consumer Safety (SCCS).
