Intellectual and scientific content of the study, design the protocol, acquisition and interpretation of data, statistical analysis, critical revision. IV . The same pattern was observed in Group III. At 30 and 60 days, the lowest setting significantly sustained contraction. CONCLUSION:Lower fractional CO 2 laser energies associated to pulse stacking could cause consistent and long lasting tissue contraction in rats.Key words: Lasers, Gas. Skin Aging. Laser Therapy.

Fractional 532‐nm KTP diode laser and 595‐nm pulsed dye laser in treatment of facial telangiectatic erythema

“…Therefore, there is theoretically a lower risk of producing epidermal damage at laser is comparable in the efficacy and safety including pain, redness, and purpura to the 595-nm PDL in the treatment of erythema like telangiectasia or erythematous surgical scar. 6,12 In the present study, pain and erythema were slightly lower in the fractional 532-nm KTP laser-treated group than in the PDL group, but it was not statistically significant. In this study, we applied the concept of fractional photothermolysis to the traditional 532-nm KTP laser.…”

“…Therefore, there is theoretically a lower risk of producing epidermal damage at 532 nm . Some previous studies reported that 532‐nm KTP laser is comparable in the efficacy and safety including pain, redness, and purpura to the 595‐nm PDL in the treatment of erythema like telangiectasia or erythematous surgical scar …”

Potential Efficacy of Multiple-shot Long-pulsed 1,064-nm Nd:YAG in Nonablative Skin Rejuvenation: A Pilot Study

“…Motta and colleagues demonstrated better skin tightening with fewer side effects using multiple stacked shots of a fractional CO2 laser in a rat model compared with higherfluence single shots. 16 Lee demonstrated that stacked shots at a low fluence with an Er:YAG laser gave good efficacy with minimal side effects in vaginal rejuvenation. 17 The present study has shown this concept worked well with the parameters and laser system used, and could offer an ideal minimally-invasive approach for NSR of mildto moderately-aged skin.…”

Combined microwaves and fractional microablative CO2 laser treatment for postpartum abdominal laxity

“…However, while surgical correction produces the most definitive results, it also requires time for patients and carries inherent risks 7 . Fractional ablative lasers as well as noninvasive devices, such as radiofrequency (RF), high‐intensity Focused Ultrasound (HIFU), nonablative Lasers, Infrared (IR), and pressure energy devices, alone or in combination, have also been used to mitigate skin laxity and reduce body circumference, improving the esthetic appearance and self‐confidence of patients 8‐10 …”

“…7 Fractional ablative lasers as well as noninvasive devices, such as radiofrequency (RF), high-intensity Focused Ultrasound (HIFU), nonablative Lasers, Infrared (IR), and pressure energy devices, alone or in combination, have also been used to mitigate skin laxity and reduce body circumference, improving the esthetic appearance and self-confidence of patients. [8][9][10] In the last years, the demand for esthetic procedures for skin tightening, minimizing downtime and side effects, has increased.…”
