As sebum production lays the groundwork for eruptions, the affected follicles eventually become plugged up. Different kinds of blemishes come under the category of acne. Whiteheads are small, closed white bumps that emerge when a follicle clogs and swells. Blackheads are the tiny, dark, raised bumps that appear when the pore of a clogged follicle remains open. Papules are red, swollen pimples that pop up when a clogged follicle releases its contents into the surrounding tissue and produces inflammation.
Pustules are pus-filled inflammations caused by an attack of white cells on the follicle's contents.
Here are some of the options. A refrigerant is sprayed on the area, numbing the skin and creating a firm surface. The area is then sanded with a spinning stainless steel wheel studded with minuscule industrial-grade diamonds. The sharp edges of the scar are planed down, and the base of the scar is also abraded, which may stimulate some growth in the center and overall smoothing of the surface. If scarring is severe and deep, the process can be repeated in six months to a year.
