Benzoic Acid Skincare Benefits:
Product Stabilizer

Benzoic acid is an alkyl benzoate preservative that occurs in nature in cherry bark, raspberries, tea, anise, and cassia bark. Benefits of benzoic acid in skincare include anti-aging, soothing, and moisturizing properties. In addition, a major derivative of benzoic acid, known as phenolic veratric acid, contains high concentrations of antioxidants to help neutralize free-radicals present in the environment. As a preservative, benzoic acid possesses a wide variety of cosmetic applications, including product stabilizer, fragrance additive, and emollient. 1

For this reason, it can be found diversely throughout products such as sunscreens, lipsticks, and lotions. As a product stabilizer, benzoic acid helps to regulate pH and protect the integrity of ingredients. Topical application of benzoic acid may also play a role in reinforcing skin barrier function, thus promoting the skin’s ability to retain moisture. With its benefits combined, benzoic acid is equipped to improve the quality of both skin and skincare products. 2
Together, these characteristics help to alleviate dry skin and improve the skin’s ability to retain moisture. 1
