@hway What’s the pH of the commercial product?

It’s pH 4-5

I would say try again at 1% at the indicated pH range.  It’s also possible they could have gone much higher, say 3-4% carbomer.
What’s your order of addition? They do have TEA listed higher than carbomer, so maybe they are neutralizing and then breaking the carbomer/ reducing pH using the aloe (possibly some of the vitamin C or DHA too) which contains electrolytes that most grades of carbomer (especially 980) will be sensitive to.

I just saw this! I tried 0.9 % of carbomer. Because I thought they must have twisted the order of the list based on their pH. I’ve done both ways(1. Aloe->Neautralizing 2. Neutralizing->Aloe.) with different TEA/Aloe %. cuz I also thought of electrolytes of Aloe.
I haven’t seen any peeling effect so far.

If Vit C dropped the pH, their order could be right! I’ll try Vitamin C/DHA/high % of Carbomer.
Thanks very much for your advice. It is really helpful!!

It’s likely the carbomer, if the pH is 4-5 they aren’t neutralizing it fully and that may be pilling and giving the appearance of skin flaking off. How much carbomer were you using and what grade, and were you staying in the same pH range?

It was carbopol 980. And I used 980 from 1% to 2 % with pH 5 to 8 variations. I’ll try again with pH 4-5 range. Thanks very much! Do you have any ideas with carbomer %?
