Ask about Lactic Acid.

inquire about Lactic Acid (AHA) 88% that if you want to mix the toner Lactic Acid 10% amount 100 g. must be weighed Lactic Acid to 11.36 g. Then add 100 g of water, right? [ !-- s:?: -->:?: P.S. Usually use glycolic acid 10% 2-3 times a week already without any irritation. But I want to try to switch to Lactic Acid some because it has the added feature Ceramide under the skin too. Thank you in advance for your answer.
