Abstract

BACKGROUND:

Both ultrapulse-mode and superpulse-mode fractional CO2 lasers (UPCO2 and SPCO2) could be successfully used in treating photoaged skin.

OBJECTIVE:

This evidence-based study was intended to compare the therapeutic and adverse effects of UPCO2 and SPCO2 in treating photoaged skin in Chinese subjects.

METHODS:

Eighteen Chinese subjects with Fitzpatrick skin type IV were enrolled in a randomized, split-face trial. Subjects received SPCO2 on one half of the face and UPCO2 on the other half. Before and after photos, skin color, epidermal water content, sebum level, periorbital wrinkles, skin roughness, and self-esteem questionnaires were used.

RESULTS:

Global evaluation and subjects' self-esteem assessments showed a similar trend at 1-month and 3-month follow-up visits on both sides. The UPCO2 laser has a shorter downtime of 6.25±2.71 days compared with 6.41±2.67 days for SPCO2, but has a higher incidence of edema, spot bleeding, prolonged redness and postinflammatory hyperpigmentation. More subjects prefer SPCO2 treatment because of similar efficacy and fewer adverse effects.

CONCLUSION:

The effectiveness of the SPCO2 laser in treating photoaged skin is very similar to the UPCO2 laser, with less erythema, but more crusting and longer downtime.
