Glycolic acid toner exfoliates the skin's surface, removing dead skin cells and promoting a brighter, smoother complexion. This process can also help to minimize the appearance of pores, fine lines, and uneven skin tone.

Avoid using glycolic acid with other strong exfoliants like retinol, vitamin C, or benzoyl peroxide in the same application. Combining these ingredients can lead to excessive irritation, redness, and dryness.

Glycolic acid may help with dandruff due to its exfoliating properties. By removing dead skin cells from the scalp, it can reduce flakiness associated with dandruff, though specialized dandruff treatments are generally more effective.

Glycolic acid can cause skin irritation, redness, and dryness, especially with overuse or high concentrations. Sun sensitivity is also a significant concern; diligent sunscreen use is essential when using glycolic acid.
