@Perry Yes, of course. 100% agree with you. Companies definitely have to prove that it’s safe for consumer use. I just meant that there are many companies that do use over 10% AHA. PC is a good example of that.
@Haleemah@Microformulation you can definitely use higher than 10% AHAs in your products without the “for professional use only” wordings. The recommendation on the FDA website is just a guideline. Lots of brands use much higher % of AHAs. But they generally also have a base that neutralizes a lot of it and hence is at a higher pH than 3.5.
