Detailed answer

Glycolic acid is an alpha hydroxy acid (AHA) that works by exfoliating the skin's surface, removing dead skin cells and promoting cell turnover. This exfoliation helps to fade hyperpigmentation and dark spots, resulting in a more even skin tone. Additionally, glycolic acid stimulates collagen production, which can improve the overall texture and appearance of the skin. It is important to note that glycolic acid should be used cautiously and properly, as it can cause skin sensitivity and irritation if not used correctly. It is advisable to start with a lower concentration and gradually increase the strength based on your skin's tolerance. Also, sun protection is crucial when incorporating glycolic acid into your skincare routine to prevent increased sensitivity to UV rays. It is recommended to consult with a skincare professional to determine the appropriate glycolic acid product and usage for your specific skin concerns.
