[quote="ssper1997"]If you want to make a toner using the
BHA Normal. Which one should I wear?
I'm not a staff member, but while waiting for staff to answer, I tried to search old information. Let's answer first in case it can help. In the past, C7 used to share the formula
BHA Toner 1)
Propylene Glycol 40-45% 2)
Salicylic Acid conventional 1.5-2% 3)
Polysorbate 20 4.5% 4) water (complete 100%) 5)
สารกันเสีย Mix 1,2 3 to dissolve completely first, then add water. This formula has disadvantages:
Propylene Glycol is so large that you may feel greasy on your face. But if you use it as a toner, wipe it with a cotton pad, it's fine. Either way, you can try it or wait for the staff again.
