If you are new to almond acid, I suggest you choose almond acid from Darf. First of all, the concentration classification is relatively broad. You can brush from 6% concentration, and your face is very gentle. After establishing skin tolerance, use the essence of Dr. WU8% almond acid to close the mouth and shrink the pores. The effect is super good, and fragile muscles can be used. After using it for a month or two, you can really see that your mouth is gone, especially for red and swollen acne. I brush it once every morning and evening, and a bottle can last for a long time ~
