Science

Mechanism of Action

Folic acid operates at a cellular level, stimulating fibroblasts to increase collagen production, thereby improving skin firmness and reducing the appearance of premature aging. As a potent antioxidant, it neutralizes free radicals, mitigating oxidative stress from UV radiation and pollution. It also fortifies the skin barrier by promoting ceramide synthesis, leading to enhanced hydration and moisture retention. Furthermore, it aids in DNA synthesis and repair, supporting healthy skin cell turnover and accelerating the healing of blemishes and sun damage, while potentially reducing hyperpigmentation for a brighter complexion.

Stability

Folic acid is susceptible to degradation by heat and light, particularly UV radiation. For optimal stability and increased water solubility, formulations should maintain a pH of 6.5 or higher. It is recommended to pre-neutralize folic acid in a separate water phase and incorporate it into formulations below 40°C. The inclusion of antioxidant agents is advised to enhance stability, and products should be packaged in opaque containers and stored away from direct sunlight in a cool, dry environment.
