Want to mix skin cream, apply on the dry part by using Urea cream + AHA 88% concentration
but not confident about the ratio and safety
If using 20% Urea cream mixed with 88% AHA in a ratio of 9: 1
Is it safe to use every day?
hello
Exfoliation should have a proportion of Lactic Acid , only about 20%, more than this can irritate the skin too much.
