What bothers you: Scar are noticeable for multiple reasons. First what color are they ? If pink then they are still healing. If brown then bleaching creams may help. If the are deep and creating shadows then excision or fat grafting may help. There are so many options, many more than cane be explained here. It is worth a visit to a board certified plastic surgeon to understand your options.

May help: Lots of options for acne scars. Unfortunately no one treatment is perfect and they are difficult to treat. Three basic approaches: surface treatments, "resurfacing" (ie laser or dermabrasion), volume treatments (injectable fillers to "plump up" the depressed areas) and excisional treatments as for for localized areas or through stretching the skin as with a form of facelift.
