Fractional CO(2) laser treatment vs autologous fat transfer in the treatment of acne scars: a comparative study.
Acne scars present a highly challenging and frustrating clinical problem. Fractional CO2 laser treatment has led to marked improvement in scars, and fat transfer, or fat grafting, has also recently proven very useful in regenerative medicine. ⋯ Fat grafting proved to be more effective in the treatment of acne scars than ablative fractional CO2 laser treatment. There were many points in its favor, the most significant being the clinical improvement in scars and texture. This supports the stem cell theory of adipose tissue in regenerative medicine.
