one of the best ways to ward off blackheads and prevent pimples is to exfoliate your skin regularly. this helps remove that top layer of dead skin cells and makeup that could clog your pores. buying exfoliating products can be expensive and having facials done professionally can be even more expensive! here is a video showing how to do this yourself with Baking Soda (the magical box, it can do anything). even i was surprised at how well it exfoliated my skin and left it feeling smooth. having had the expensive treatments done, i was very impressed with the results.
