If the skin is usually sensitive, use glycolic acid or retinol alone first, and then use it in combination when the skin adapts. At the beginning, the frequency of use should be low, such as once a week, and then gradually increase to two to three times a week. And when using, it should be thinly applied first to observe the skin's reaction.
