2,5-DIHYDROXYBENZOIC ACID

Description

2,5-Dihydroxybenzoic acid, also known as gentisic acid, is a naturally occurring organic compound found in various plants and fruits. This dihydroxy derivative of benzoic acid has gained significant attention in skincare formulations due to its multifaceted properties. As a potent antioxidant, it helps neutralize free radicals and combat oxidative stress, which contributes to premature skin aging.

The compound exhibits mild exfoliating properties, aiding in the removal of dead skin cells and promoting a smoother skin texture. Its anti-inflammatory effects make it beneficial for soothing irritated skin and potentially reducing redness associated with various skin conditions. 2,5-Dihydroxybenzoic acid also demonstrates antimicrobial activity, which may help in managing acne-prone skin.

In skincare products, it is often used in concentrations ranging from 0.1% to 2%, depending on the formulation and intended benefits. It can be found in serums, moisturizers, and targeted treatments. The ingredient is generally well-tolerated by most skin types, but as with any active compound, patch testing is recommended before widespread use. Its ability to enhance the efficacy of other skincare ingredients, particularly vitamin C, makes it a valuable addition to comprehensive skincare regimens.
