If you want brush acid, you'd better choose almond acid as the corresponding fruit acid, because it is skin-friendly and won't be too irritating to your face. If it is moderate and suitable for the student party, I can only think of Dr. Wu's almond acid. Sisters can choose the 8% concentration. I am allergic to skin in different seasons. I use Dr. Wu's almond acid all the year round, usually once every two days. Basically, you can see the effect in a week or so. The mute of my chin and forehead is particularly obvious, with high cost performance, which is very suitable for the student party!
