3-HYDROXYBENZOIC ACID

Description

3-Hydroxybenzoic acid, also known as m-hydroxybenzoic acid, is a naturally occurring aromatic compound found in various plants and fruits. This organic acid belongs to the family of phenolic compounds and is structurally related to salicylic acid, a well-known exfoliant in skincare.

In skincare formulations, 3-hydroxybenzoic acid serves multiple purposes. It acts as a preservative, helping to extend the shelf life of products by inhibiting microbial growth. Additionally, it possesses mild exfoliating properties, assisting in the removal of dead skin cells and promoting cell turnover.

The compound exhibits antioxidant properties, potentially protecting the skin from free radical damage. It may also have anti-inflammatory effects, which could be beneficial for sensitive or irritated skin. Some studies suggest that 3-hydroxybenzoic acid may have a brightening effect on the skin, potentially helping to reduce the appearance of hyperpigmentation.

When formulating with 3-hydroxybenzoic acid, it's typically used in concentrations ranging from 0.1% to 0.3%. It's generally well-tolerated but should be used cautiously in products for sensitive skin. As with any active ingredient, patch testing is recommended before widespread use.
