HEPES

Hydroxyethylpiperazine Ethane Sulfonic Acid (HEPES) is an important ingredient in cosmetics for its role as a pH buffer and stabilizer. It helps maintain the stability and efficacy of cosmetic formulations by ensuring that the pH remains within an optimal range. Its solubility and safety profile make it a valuable component in various skincare products, from cleansers to serums. While HEPES is generally well-tolerated, as with any ingredient, checking for compatibility with your skin through patch testing is recommended.
