Summary

Skin conditioning Antioxidant Anti-aging Brightening Evens skin tone Collagen support Hydration Sebum regulation Antimicrobial Anti-inflammatory

Science

Mechanism of Action

This ingredient functions as a powerful antioxidant primarily due to its high concentration of Vitamin C (ascorbic acid), along with carotenoids and polyphenols. These compounds effectively neutralize free radicals, shielding the skin from oxidative stress and photoaging. It contributes to skin conditioning by forming a protective layer that retains moisture, while also supporting collagen synthesis through the acceleration of proline and lysine hydroxylation. Furthermore, it aids in evening skin tone by reducing melanin levels and inhibiting tyrosinase activity, enhances barrier function, helps regulate sebum, and exhibits soothing antimicrobial and anti-inflammatory properties.

Key findings

  1. 01 Concentrations of 5.0%–10.0% are utilized in cosmetic formulations when supplied in a water and glycerin base, with topical collagen support inferred from its high Vitamin C content, despite most direct collagen research focusing on ingestion.
  2. 02 As an effective antioxidant in cosmetic emulsions, commercial acerola extract has shown efficacy at 1% or 5% concentrations.
  3. 03 An aqueous acerola fruit extract demonstrated significant reduction of cellular melanin and inhibition of tyrosinase activity in B16 mouse melanoma cells in a concentration-dependent manner, indicating skin-whitening potential and strong antioxidative activity. Human skin patch tests showed no allergic reactions.
  4. 04 Patented compositions utilizing acerola cherry fermentate with organic acids have been developed to enhance skin desquamation, and in combination with other known agents, for skin whitening purposes.
