Salicylic acid (BHA) has been found to be effective at keeping pores clean.
Most acne occurs because dirt, debris, and skin oils accumulate in the pores and clog them. As we know, clogged pores lead to acne.
Once applied to the face and neck BHA enters the pores and has dual actions...it exfoliates and removes dead skin cells quickly, preventing the pore from becoming congested.
As BHA is a Keratin-dissolving acid there is no need to rinse the face after application.
