The concentration of the AHA/BHA toner is quite low and most probably wonât show immediate purging. The possible cause maybe that your skin barrier is already weak to begin with such that AHA/BHA can quickly causes an irritation on your skin. Before the toner, have you ever introduce other exfoliating acids* or retinoid* or benzoyl peroxide* in your routine?
Since your skin is currently irritated, I would highly recommend to stop using it! You may patch test it on skin region behind your ear to test it out again after a few days. If irritation still occurs, you may want to slowly introduce it in your routine. Rules of thumb, avoid using exfoliating acids daily. As your skin barrier seemed to be weak, you should try using it 2-3times per week, mon wed fri or so. Avoid using it with the three ingredients stated above with a â*â. Always use a sunscreen the next day after using it, and that use the toner at your PM routine.
The mentioned weak skin barrier can be remedied with moisturizer that consists of ceramidesđ
