In terms of whether it is appropriate to use glycolic acid after salicylic acid
for skin care, both salicylic acid and glycolic acid are commonly used agents. However, after using glycolic acid in salicylic acid, the advantages and disadvantages are worth exploring.

Salicylic acid has the power of dredging pores and exfoliating, which can peel off the old stratum corneum on the surface of the skin and make the skin rejuvenated. However, it is more intense, used too much, or cause skin discomfort, such as redness and tingling.

Glycolic acid is also an exfoliating product, which can penetrate deep into the skin, promote cell renewal, and improve skin quality. If used after salicylic acid, both have the ability to exfoliate, and may be superimposed. The stratum corneum of the skin is originally a barrier against external invasion. Excessive exfoliation, the barrier is damaged, and the skin is prone to sensitive states. It is intolerant to external stimuli, such as hot and cold, and cosmetics can cause discomfort.

However, if the skin is well tolerated, and the dosage and interval are appropriate, it is also beneficial to use glycolic acid after salicylic acid. If low-concentration salicylic acid is used first to make the skin slightly adapt, after appropriate intervals, low-concentration glycolic acid is used, step by step, or it can enhance the effect of exfoliation and improvement of skin quality, making the skin more delicate and smooth.

Therefore, after salicylic acid is used glycolic acid, when the skin is tested for tolerance, the amount of dosage and the length of the interval are determined. If the skin is sensitive, you need to be cautious or consult a professional to ensure skin health and achieve the good results of care.
