“CosRX BHA Blackhead Power Liquid and CosRX AHA Whitehead Power Liquid - Really good at getting rid of whiteheads and sebaceous filaments.”
“I believe CosRX has a toner with both AHA and BHA now but I just got so used to applying these separately (BHA in the AM, AHA every other PM) that I don't want to change.”
