Some adults carry scars from acne. Some relatively aggressive surgical procedures can improve scars. Procedures include dermabrasion , several types of lasers, injections under the skin called "fillers," and chemical peeling. These procedures remove the scarred surface and expose unblemished skin layers. Dermatologists also occasionally use glycolic acid and other chemical peels to loosen blackheads and decrease pimples. Microdermabrasion has little effect on acne itself, but is effective in combination with lasers.. Before considering such treatment it is important to discuss the procedures, necessary precautions, and likely results with a doctor.
What causes baby acne ? The exact cause of neonatal acne is not known. It has been suggested that possibility of a normal inflammatory or immune system response in babies could be a cause. There have not been any confirmations on whether this could be related to allergies or whether the baby is breastfed or formula fed. According to , it is thought that baby acne is caused by exposure to maternal hormones in the womb which cause overproduction of sebum clogging pores of the skin. They can last for weeks or even months on baby’s skin.
