Not all BHA cleansers are formulated the same way.
This collection contains Korean Low pH BHA Cleansers that combine salicylic acid (BHA) with a low pH cleansing system to support classic BHA performance while cleansing the skin.
At BKS, low pH BHA cleansers are classified separately from traditional high-foam alkaline BHA cleansers because they represent different formulation approaches and intended use.
BKS Classification Rule: Products receive this classification only when both BHA and low pH positioning can be verified through official brand information.
