Getting rid of scars is a difficult problem. By their nature scars are formed below the outermost layer of skin, which makes them deeper than problems such as acne.
The Glycolac/60 acts in two ways which helps to reduce the scar appearance. It helps remove the outer layers of the skin forming the scar and it works beneath the surface of the skin to stimulate collagen production which thickens the skin and reduces the appearance of the scar. Often it is not possible to completely remove a scar, but their appearance can be improved and their size diminished.
For superficial scars, the Glycolic/35 and Lactic/50 are both good. The Glycolic stimulates collagen growth slightly better, while the Lactic has the edge at treating hyperpigmentation. Most scars are noticeable because of the pigmentation differences, and this is most treatable through chemical peels. Large scars will require more invasive procedures from a doctor for the desired result.
