Removing Scars on Face and Legs?

Right, you cannot 'remove' a scar as only a dermatologist or cosmetic surgeon can do that, as they literally "cut it out" of the skin, and they call that "scar revision" since it is skin that just formed differently than the rest of your skin, as the skin did it's own repair when the wound happened, but you can minimize the appearance with daily use, or every other day use of Glycolic Acid creams. You probably want to start out with a low percentage, 5%, then as your skin becomes use to it (it stings upon the first application) like Retin A, which that's good too to use, and you can graduate to a stronger percentage in a few weeks.

This causes cellular renewal, and the cells to turn over faster, which that is what will help minimize it over time. Our skin does this process naturally, but as we get older, it does it very slowly.
Glycolic Acid creams or lotions cause the skin to speed up that now slowed down process. Which the more cellular turnover, the more the mark or scar on the skin fades away, because it is going away.
It all depends on how deep the skin was wounded also. For a dark mark, you could even have a light peel done on just that spot/area, and that might do the job in just one sitting.
