Subcision is a process used to treat deep rolling scars left behind by acne or other skin diseases. It is also used to lessen the appearance of severe glabella lines, though its effectiveness in this application is debatable. Essentially the process involves separating the skin tissue in the affected area from the deeper scar tissue. This allows the blood to pool under the affected area, eventually causing the deep rolling scar to level off with the rest of the skin area. Once the skin has leveled, treatments such as laser resurfacing , microdermabrasion or chemical peels can be used to smooth out the scarred tissue. [ citation needed ]
He's nearly done with his math homework for the day when the reporter's voice fizzles out. At first he doesn't notice, but then the static blares, and his pencil jerks and scores a dark line on his paper. Grumbling to himself, he shoots the TV a scowl. The screen blinks black, then static. The whiteness falters and shorts out, and for a split second it looks like the picture might be coming back. Or... a picture, anyway. It doesn't look much like the news. It looks like a video of an empty room, but it blinks out too rapidly for Izuku to tell for sure. As he watches, the image breaks up and gives way to static once more.
