What molecule size category does glycolic acid fall under compared to other chemical peels?

Glycolic acid is classified as having one of the smallest molecule sizes among commonly used chemical peels. This small size enables it to penetrate the skin effectively and reach deeper layers compared to larger molecules found in other types of chemical peels. As a result, glycolic acid is often used for its ability to exfoliate the skin effectively, stimulate collagen production, and improve the overall texture and appearance. Its efficacy in treating conditions like acne, sun damage, and signs of aging is largely attributed to this small molecular structure, allowing for enhanced absorption and effectiveness. The other categories, such as medium or varying sizes, do not accurately reflect the uniquely small molecular profile of glycolic acid when compared to other chemical peel agents.
