Hydroxyethylpiperazine Ethane Sulfonic Acid (HEPES)

Overview

Hydroxyethylpiperazine Ethane Sulfonic Acid, commonly known as HEPES, is a widely used buffering agent in cosmetic formulations. It plays a crucial role in maintaining pH stability, which is essential for the efficacy and safety of various skincare products.

Clinical Evidence

Integrated Skincare Active Ingredients

The importance of selecting appropriate active ingredients for integrated skincare (ISC) has been highlighted in a study by Bjerring et al. This study emphasizes the need for effective buffering agents like HEPES to enhance the outcomes of medical aesthetic procedures. For more details, refer to the article International Expert Consensus on Integrated Skincare Active Ingredients for Pretreatment and Posttreatment Use With Medical Aesthetic Procedures to Enhance Skin Benefits.

Emollients for Xerosis Cutis

HEPES may also play a role in formulations aimed at treating xerosis cutis, as discussed in a review by Wollenberg et al. The study underscores the significance of maintaining skin hydration and barrier function, where buffering agents can contribute to the overall effectiveness of emollient therapies.
