Sonnerphenolic B exhibits significant antioxidant properties, making it valuable in cosmetic and skincare formulations aimed at reducing oxidative stress and signs of aging. It has been studied for its ability to inhibit enzymes involved in inflammatory pathways, suggesting potential use in topical anti-inflammatory products. Additionally, its natural origin and polyphenolic structure support its application as a stabilizing agent in natural product formulations, helping to prevent degradation of active ingredients by scavenging free radicals. Research also indicates antimicrobial activity against certain skin pathogens, which may lend itself to use in acne treatment or preservation systems within personal care products.
