Glycolic acid and betaine: work well together

Work well together

Apply glycolic acid first and betaine right after to keep skin calm and hydrated. Glycolic acid can dry out the skin, while betaine adds back essential moisture. If skin feels sensitive, use a gentler acid or wait a few minutes between steps.
