Science
Mechanism of Action
Soy Isoflavones exert their effects by binding to estrogen receptors within the skin, which promotes increased synthesis of collagen and elastin. This action leads to demonstrable improvements in skin elasticity, texture, density, and overall resilience. They are potent antioxidants, effectively neutralizing free radicals to protect against oxidative damage and environmental aggressors. Furthermore, these compounds possess anti-inflammatory properties, capable of soothing inflamed skin and reducing redness. They also contribute to a more even skin tone by inhibiting tyrosinase activity, which reduces melanin transfer and helps fade hyperpigmentation, age spots, and melasma. Additionally, Soy Isoflavones enhance skin hydration by increasing hyaluronic acid concentration and support natural skin repair and regeneration through stimulated keratinocyte growth.

Key findings
- 01 Topical application over 24 weeks significantly enhanced hyaluronic acid concentration, increased epidermal thickness, and augmented the number of blood vessels in postmenopausal skin.
- 02 A double-blind, placebo-controlled study with 21 volunteers demonstrated a significant increase in dermal papillae following topical application, indicating rejuvenation of the dermal-epidermal junction in aging skin.
- 03 Twice-daily topical application for 3 months modified the extracellular matrix (ECM) composition and dermal network structure, contributing to improved skin architecture.
