I put on aczone, benzaclin, and a light mosturizer morning and night, and I have noticed since starting the benzaclin my acne has cleared up and not many new pimples have formed, although in places where I had dark spots and felt like a pimple was underneath my skin a few pimples have surfaced. Is that normal for benzaclin to purge the skin in a way at first to get rid of all the pimples under your skin and then preventing new ones?
