I would like to know if the pH has to be lowered to 3-4 again. Yes, so that BHA the skin. สิวอุดตัน or mix and use. Ignore pH

Hello for working for ผลัดเซลล์ผิว of BHA does not need to work at low pH, it can work at pH above 4, so the formula doesn't need to adjust the pH. ผลัดเซลล์ผิว with the formula, the pH must be adjusted to lower the pH level not more than 3.5 will be suitable for work. ผลัดเซลล์ผิว of the hydroxy acids group ( AHA , BHA , PHA)
