Background:
The CO2 and erbium: YAG (Er: YAG) lasers have been used for skin resurfacing. A recently developed system combines pulsed ablative Er: YAG and continuous wave subablative CO2 wavelengths in one console.
Objectives:
To assess the potential benefits of this system.
Methods:
The study follows 102 women, skin types I-V, with 26 full face, 48 perioral and 28 periocular resurfacing procedures. The ablative Er: YAG pulse (350 micros, 29 J cm(-2)) is followed immediately by a non-ablative CO2 laser shot (4-6 W, 50 ms) through the same collimated handpiece (3-mm diameter spot), 50% overlapping, repetition rate 10 Hz, giving two-pass equivalence with one single pass.
Results:
Patients scored the results as very good (n = 67), good (n = 25) and fair (n = 10). Mild but successfully resolved side-effects occurred in only four patients. The 2-month histology showed a good band of new collagen tightening the overlying healthy epidermis. Follow-up periods ranged from 1.5 to 2 years (mean +/- SD 1.76 +/- 0.33).
Conclusions:
This device at the above settings offers speedy resurfacing without compromising the quality of the procedure for the patient, and may well satisfy the basic requirements of laser skin resurfacing.
