An exfoliating serum to target blackheads, blemishes and uneven complexions.
Each evening, apply three to four drops of glycolic acid serum to your face. Avoid using it in the morning, or being exposed to the sun after application. Limit sun exposure for at least one week after using.
In the case of redness or a visible skin reaction, alternate between the serum and the exfoliating toner each evening.
