Is there any non-surgical way for getting rid of acne atrophic scars over the face?

CIT & fat grafts: I have found that collagen induction therapy with needling and fat grafting can provide some improvement in atrophic scars. Others may require excision.

Dermabrasion?: Dermabrasion or laser resurfacing may help to smooth out the surface by flattening the non-atrophic areas between the scars. Whether you consider these treatments to be non-surgical or not is a different matter. Significant recovery and the possibility for complications (color changes, lighter or darker, chiefly) are possibilities with both.

Yes but...: Depends on what you consider non-surgical. Peels, lasers, and/or dermabrasion all may help. Seek a local facial plastics md or dermatologist for good recommendations.

Yes: Ablative laser is effective in improving if not completely removing acne scars. However, ablative lasers (co2, erbium, fractional ablative) do have 7-10 days (or more) of down time, and are performed by mds only.
