Is mandelic acid effective for enlarged pores?

In general, mandelic acid can be effective in improving enlarged pores. The detailed analysis is as follows:

Mandelic acid is a type of alpha hydroxy acid (AHA) and currently the only lipophilic fruit acid available. It can penetrate deeply into pores, working gently without irritation to effectively improve various skin concerns such as acne, blackheads, and enlarged pores. For individuals with oily skin, excessive sebaceous gland secretion is one of the main causes of enlarged pores. Mandelic acid helps reduce sebum production, thereby improving pore size. Additionally, it accelerates skin renewal and metabolism, stimulates pore tightening, achieves deep skin repair, and makes pores appear finer and smoother.

However, when using mandelic acid, it's important to follow correct methods and usage frequency to avoid unnecessary irritation or damage to the skin. It is recommended to follow a skincare routine in this order: makeup removal, cleansing, mandelic acid serum, toner, other serums, moisturizer or cream, and sunscreen/physical protection. Furthermore, use should be guided by a medical professional to ensure safety and optimal results.
