Function & Applications

Caffeic Acid is a multifunctional antioxidant used in cosmetic formulations to enhance product stability, protect skin from oxidative stress, and support uniform tone. As a naturally occurring hydroxycinnamic acid, it delivers active defense with formulation-friendly behavior:

• Antioxidant Booster: Reinforces oxidative stability in emulsions and active serums
• Skin Brightening: Supports more even-looking complexion over time
• Photo-Protection Support: Helps reduce oxidative stress from UV and pollution exposure
• Preservative Potentiator: Synergistic effect with natural antimicrobial systems

Common uses: antioxidant creams, night serums, anti-pollution skincare, SPF-supportive products, and hair protection formulas. Suitable for industrial-scale production requiring standardized polyphenolic ingredients.
