Science
Mechanism of Action
Pueraria Mirifica contains potent phytoestrogens, notably miroestrol and deoxymiroestrol, which subtly mimic estrogen's effects within the skin. This bioactivity is believed to support enhanced skin moisturization, improve dermal firmness and elasticity, and contribute to the visible reduction of fine lines and wrinkles. Furthermore, this ingredient aids in optimizing skin texture, promoting cellular renewal, and offers antioxidant protection while assisting in the maintenance of the skin's natural pH balance.

Key findings
- 01 A topical gel containing 1% Kwao Krua (Pueraria mirifica) significantly enhanced vaginal tissue health, pH, and skin tone in postmenopausal monkeys over a 28-day period.
- 02 A Kwao Krua cream demonstrably improved symptoms of vaginal irritation and dryness in 71 postmenopausal women over a 12-week study, although its efficacy was noted to be less than a standard estrogen cream.
- 03 An anti-wrinkle formulation containing 0.6% (w/w) Pueraria candollei var. mirifica extract (PCM) was observed to decrease both wrinkle surface area and volume in postmenopausal women after just 7 and 14 days of application.
- 04 A Pueraria Mirifica extract (ABS Pueraria Mirifica Extract PF) boosted skin moisture levels by 39% after 24 hours, retaining a 26% improvement over an untreated control after 3 weeks. It also showed 37% superior moisturization at 24 hours and 7% better at 3 weeks compared to a base cream.

The Formula
Formulation
Stability
For optimal stability and to mitigate potential odor development, this ingredient should be incorporated into formulations at temperatures below 50°C. Prolonged exposure to temperatures exceeding 30°C in aqueous solutions may lead to the production of a strong odor. The recommended formulation pH range is between 3 and 9.
Conflicts
- High temperatures (above 30°C for prolonged periods in aqueous solutions)
Safety
Safety Profile
The specific ingredient 'PUERARIA MIRIFICA ROOT POWDER/PROPYLENE GLYCOL FERMENT FILTRATE' has not been directly assessed by CIR, SCCS, or FDA for safety. General Pueraria mirifica root extract is listed by EWG Skin Deep with low concerns regarding cancer, allergies, immunotoxicity, developmental and reproductive toxicity, and use restrictions. However, these assessments pertain to the broader extract, not specifically this ferment filtrate form.
