Overview

Key Ingredients & Benefits

This glycolic acid serum is powered by a 9.8% concentration of glycolic acid, which acts as a potent exfoliant, helping to accelerate skin turnover and improve skin texture. By dissolving the bonds between dead skin cells, it reveals fresher, brighter skin. Alongside glycolic acid, the formula is fragrance-free to minimize irritation, making it ideal for those with sensitive skin. Regular use can help smooth fine lines and reduce the appearance of dark spots, leading to a more even skin tone. This lightweight treatment offers visible results with minimal risk of irritation.

Best For

It works especially well for those with normal to oily skin, who may need a gentle yet effective exfoliant to remove buildup and improve skin clarity. Those concerned with uneven skin tone or visible blemishes will benefit from its ability to reduce dark spots and fine lines. Additionally, the fragrance-free formula makes it suitable for sensitive skin users who want a product that delivers results without irritation.
