Glycolic acid and ascorbyl glycosides

Posted by Dtdang on March 17, 2022 at 4:27 pm

Good morning!
I appreciate all answers and thank you so much in advance.
Are glycolic acids and vitamin C (ascorbyl glycosides) compatible for facial cream ?

Any specific attention that I must be aware?

You might take a look at the pH for best bioavailability on both of those, before you formulate with both in a shared emulsion.

@CedarS Thanks a lot!
Glycolic 70% + other AHA acids have pH= 4.5 to 5.5, actually 5.1
ascorbyl glycosides has pH =[4, 6], actually 4.0
