Dermabrasion is used to remove sun-damaged skin, lessen scars and dark spots on the skin. It is useful when the scar is raised above the surrounding skin, but is less effective with sunken scars. Procedure
It removes the surface of the epidermis of the skin (the stratum corneum). Over several months, the dermal layer rises in place of the skin removed and skin pigment returns to normal.
Sander dermabrasion uses a small, sterilized, electric sander to remove the surface of the skin by abrasion. It is very painful and requires a general anaesthetic. Afterward, the skin is very red and raw-looking.
Laser dermabrasion uses a CO2 or an Erbium:YAG laser to remove layers of scar tissue by applying a high intensity beam of light to the skins surface, rather than a blade. It is much easier to control, to gauge and is practically bloodless.Revovery
It takes several months for the skin to regrow and heal.
Even if these procedures are done correctly by a licensed physician, the appearance of the skin where the scar was may not improve. The area where the scar was removed can actually become darker or the pores in the skin (especially around the face) can get clogged and require further surgery or you may even experience a very painful infection.
A much better method is silicone scar sheets
