Neck Rejuvenation with Fractional CO2 Laser: Long-term Results

To assess the effectiveness of 10,600nm fractional CO2 laser for neck aging at one month and one year after treatment. Design/Setting/Participants/Measurement: Twenty patients underwent 10,600nm fractional CO2 laser treatment over the entire neck. Clinical features of the patients were classified according to Baker classification. The degrees of skin laxity, jowling, fat deposition, and horizontal neck lines were evaluated using a 9-point scale, prior to treatment at one month and one year after the treatment. The patients were independently assessed by the authors at two different times in a blinded fashion.

Skin laxity, jowling, fat deposition, and horizontal neck lines scores were significantly lower than the baseline values at one month and one year. One-year follow-up values of the same parameters were still significantly lower than the baseline. No persistent complication developed after treatment.

The results of this study confirm that fractional CO2 neck rejuvenation is an effective treatment option with long-term efficacy for patients who mainly have skin laxity and jowling together with skin surface pigmentation.
