Hydroxyphenyl Propamidobenzoic Acid

How it works in skincare

In cosmetics and skincare, Hydroxyphenyl Propamidobenzoic Acid functions as a soothing and anti-irritant agent. It helps reduce the feeling of discomfort caused by environmental stressors and supports the skin’s natural defences by limiting the release of substances that can trigger visible redness and sensitivity. Formulators like its ability to work well alongside active ingredients such as retinoids, AHAs and vitamin C, making it a useful addition to products designed for sensitive or compromised skin barriers.

Where it comes from

Hydroxyphenyl Propamidobenzoic Acid is a synthetic derivative inspired by avenanthramides, the soothing compounds naturally found in oats (Avena sativa). While produced in the laboratory for purity and stability, its structure is modelled on these beneficial molecules from the oat plant.
