Use glycolic acid extracts at no more than 5% in face and body cream formulations.
Question 1 Can it be used in the daytime formula and can it be out in the sun normally?
Question 2 or should I use only at night?
The purpose is I want to use it to exfoliate blemishes, dark spots, and scars. I intend to use it at 2-3%. Do you think it's enough?
