On the advantages and disadvantages of common glycolic acid for the face
Glycolic acid is used for facial skin care, with both advantages and disadvantages, which cannot be ignored.

Glycolic acid has excellent effects. First, it can rejuvenate the skin. It can accelerate the renewal of stratum corneum cells, make old keratin shed, make the skin surface revitalized, and the skin tone is more uniform and shiny, as if it were new. Second, it can improve skin quality. Glycolic acid can penetrate deep into the skin, stimulate the production of collagen, enhance the elasticity and firmness of the skin, reduce fine lines and wrinkles, and return the skin to full and smooth. Third, it is also good for acne. It can unclog pores, remove sebum and dirt that clog pores, inhibit the growth of Propionibacterium acne, thereby reducing the production of acne and making the skin clean and refreshing.

However, glycolic acid is also risky when used on the face. It is highly acidic, and if the concentration is too high or used improperly, it is easy to cause skin irritation. In light cases, the skin is red, hot, itchy; in severe cases, it may cause rash, peeling, and even allergic reactions. And frequent skin exposure to glycolic acid for a long time may thin the stratum corneum, damage the skin's barrier function, and reduce its resistance to external stimuli, making it more susceptible to allergies.

Therefore, ordinary glycolic acid is used on the face. Although it has the ability to beautify the skin, it must be used with caution. When you choose the appropriate concentration and frequency of use according to your own skin condition, and perform a local trial first to confirm that there is no discomfort, you can use it comprehensively. In this way, you can develop your strengths and avoid your weaknesses, enjoy the benefits of glycolic acid skin care, and avoid skin damage.
