Science
Mechanism of Action
Phloretin operates through several key mechanisms: it serves as a powerful antioxidant, neutralizing free radicals induced by UV radiation and pollution to mitigate oxidative stress and prevent premature aging. It significantly inhibits tyrosinase, the enzyme crucial for melanin synthesis, thereby reducing existing dark spots and preventing new ones. Furthermore, Phloretin improves cellular turnover, exhibits anti-inflammatory properties to soothe irritation, and supports collagen integrity by preventing degradation and stimulating new production. Its unique ability to act as a penetration enhancer boosts the delivery and effectiveness of co-formulated active ingredients.

Key findings
- 01 Demonstrated a 98.2% inhibition of tyrosinase activity, a performance superior to both kojic acid and arbutin. It also enhances the inhibitory effect of other tyrosine inhibitors when used synergistically.
- 02 When formulated with 10% L-ascorbic acid and 0.5% ferulic acid, it provided advanced environmental protection, visibly improving discoloration and skin tone evenness by up to 20%. Radiance increased by up to 27%, discoloration reduced by up to 16% after 12 weeks, and fine lines decreased by up to 24% after 24 weeks.
- 03 Exhibited inhibition of elastase and matrix metalloproteinase-1 (MMP-1) activity, reduced cellular tyrosinase activity and melanin concentration, and induced apoptosis in B16 mouse melanoma 4A5 cells.

Stability
Phloretin maintains stability in acidic pH environments. However, it exhibits photoinstability and poor aqueous solubility, which necessitates careful formulation strategies. Products containing Phloretin, particularly with Vitamin C, may experience darkening upon exposure to air and light, though efficacy is typically retained. Utilizing colloidal delivery systems can significantly improve its chemical stability and bioavailability within formulations.
Synergies
- L-ascorbic acid and Ferulic acid (for enhanced environmental protection and anti-aging benefits)
- Other tyrosine inhibitors (to boost lightening efficacy)
