Use of Raman spectroscopy in the assessment of skin after CO ablative fractional laser surgery on acne scars.

Background: Ablative fractional laser surgery is a common technique for treating acne scars. However, an in vivo and noninvasive analysis of the histologic variations between acne skin and the resulting resurfaced skin is needed in order to evaluate the wound healing process of the scars induced by the ablative fractional laser surgery.

Materials And Methods: Nine patients with acne scars underwent a single treatment with a CO ablative fractional laser surgery.
