There is also a role for Bellafill and other injectable fillers, including fat, for some depressed scars. Bellafill is currently the only filler that’s approved by the U.S. Food and Drug Administration to help raise depressed scars. It packs a one-two punch by adding volume, and also encouraging collagen formation beneath the surface by creating a supportive scaffold. “Bellafill and other injectables can fill in scars but these tend to be better for one scar,” adds New York City facial plastic surgeon Jennifer Levine, MD. Filler results can last up to 18 months. “If you have a cheek full of depressed scars, it’s better to resurface the face with laser, radiofrequency, or another energy-based treatment,” she adds.
Acne is reported to be less common in people that have a diet with lower glycaemic index, eg, natives from Kitava and Papua New Guinea, the Ache people of Paraguay, Inuits and rural residents of Kenya, Zambia and Bantu. These people tend to become sexually mature at a later age than in the cities where higher glycaemic index foods are consumed. Early puberty is associated with earlier onset and more severe acne that tends to peak at the time of full maturity (age 16 to 18).
Comedo (whiteheads or blackheads) or papules. The comedo is the basic acne lesion, which is a plugged pore. If the plugged pore stays under the skin, it's called a closed comedo and forms a white bump or whitehead. Blackheads are comedos that open up and appear blackish on the surface of the skin. This black color is not due to dirt, but because the air reacts with the excess oil.
Acne (acne vulgaris, common acne) is a disease of the hair follicles of the face, chest, and back that affects almost all teenagers during puberty -- the only exception being members of a few primitive Neolithic tribes living in isolation. It is not caused by bacteria, although bacteria play a role in its development. It is not unusual for some women to develop acne in their mid- to late-20s.
