Dirt, dead cells, makeup, and other substances can form a plug in the pore. This plug (commonly called a blackhead) stretches the opening of the follicle. When the plug is removed, the follicle becomes smaller.

You already have acne forming under your skin that you aren't even aware of yet. It generally takes 3 weeks for a clogged pore to come to the surface and be seen and felt. Since you are removing the outer layers of skin at a faster pace, the blemishes that were 1,2 and 3 weeks away will come up quicker. You have to give your skin time to work these clogged pores up to the surface. Once these are out, your skin should show marked improvement. (Usually within 3-4 weeks).
As the dead cell layer sloughs off, your skin may appear slightly drier than normal. Once the transition is made, your complexion will appear more youthful and vibrant.
