Hello,
Thanks in advance for all the help I have received. 😊 I want to know which acids are good for exfoliate the skin only. I am 45 years old; my skin is combination, now is a little bit dry. I don’t want to spend a fortune, but I don’t want to damage my skin because the product is cheap. Many, many thanks.
Lactic acid is a great option because is both hydrating and exfoliating (10-15% would be a good range for using 1-2x a week). You can also use a product that contains a combination of a few acids, for example, lactic + glycolic. In this case, watch the total combined concentration of all the exfoliating acids in the product, keep it within 10-15% not to overdo it.
