Control Zero Betapore Serum 2% Salicylic Acid 4% Niacinamide Cleans pores, excess oil and dead skin This is the first time I've tried a serum with Salicylid Acid. I really need this serum because in hot weather my skin can suddenly appear small pimples in the forehead area. This serum packaging uses a black glass bottle, screw cap attached with a pipette. The texture of the serum before the drops are a little thick, but once blended it seems that the texture is watery and absorbs very quickly, this serum doesn't make me tingle at all, and I'm very comfortable because it doesn't have a scent I use Beta pore serum only at night, This serum really heals acne on the forehead, I've been using it for 2 weeks, the acne dries up really fast, the face is cleaner too
