Summary

Anti-inflammatory Antioxidant Skin-soothing Broad-spectrum antimicrobial preservative Astringent Masking

Science

Mechanism of Action

This extract derives its efficacy from a rich profile of beneficial compounds including flavonoids, saponins, essential oils, and chlorogenic acid. It functions by mitigating inflammatory responses and redness, neutralizing free radicals to combat oxidative damage, and reinforcing the skin's natural protective barrier. Additionally, its natural broad-spectrum antimicrobial action, partly attributed to parahydroxy benzoic acid (PHBA), enhances product preservation.

Sensitization risk Low

Generally regarded as safe for cosmetic use and well-tolerated, with no major adverse effects reported. Human patch tests at 3.5% concentration confirmed no irritation potential. While INCIDecoder suggests the presence of natural parahydroxy benzoic acid (PHBA) and classifies it as a natural paraben, some research indicates this may be due to false positives from incompatible reagent interactions.
