Science
Mechanism of Action
This extract operates via multiple biological pathways to optimize skin function. Its rich antioxidant profile effectively neutralizes free radicals, thereby protecting against environmental damage and mitigating premature cellular aging. At a molecular level, it stimulates collagen synthesis and dermal fibroblast proliferation, while simultaneously inhibiting collagenase and elastase, which are enzymes responsible for collagen and elastin degradation, thus bolstering skin structure and elasticity. Furthermore, in vitro studies indicate its capacity to inhibit tyrosinase for a brighter complexion, reduce sebum production by inhibiting lipoxygenase, and calm inflammation through cyclooxygenase inhibition. These combined actions result in enhanced moisture retention, visibly reduced fine lines, and an overall more luminous and youthful appearance.

Key findings
- 01 A micellar extract cream demonstrated a significant 22.31% improvement in skin hydration after 12 weeks of application, notably surpassing a placebo cream (3.52% increase) and a reference cream (13.96% increase). It also enhanced skin elasticity parameters R2 and R5 by 13.30% and 12.33% respectively.
- 02 Regular application of a cosmetic cream containing a dry extract from powdered Phaseolus vulgaris seeds for 8 weeks yielded positive effects on skin whitening, erythema reduction, sebum regulation, and overall moisturization.

Stability
Formulators should be aware that aqueous extractions may present challenges, including high viscosity, filtration difficulties, extended processing times, and increased risk of microbial contamination. Heat treatments can also compromise the ingredient's activity. To optimize solubilization, stability, and skin penetration, micellar extract formulations are recommended.
Safety
Safety Profile
While generally considered safe for cosmetic use, individuals with sensitive skin are advised to perform a patch test prior to widespread application, as mild allergic reactions such as redness or itching may occur. Regulatory bodies, including the European Cosmetics Regulation, permit its use under appropriate guidelines. The EWG Skin Deep database rates its concern levels as 'LOW' across categories including Cancer, Allergies & Immunotoxicity, and Developmental and Reproductive Toxicity.
