Photoaging – this is one type of skin aging that occurs as a result of the adverse effects of sunlight on the skin. Combating the signs of photoaging is one of the main goals of aesthetic medicine. And since lasers can be safely called one of the main tools in this field of medicine, specialists are constantly expanding the scope of laser radiation. This time, Estet-portal presents to your attention a comparative analysis of the effect of two fractional CO2 lasers on the skin in order to eliminate the signs of skin photoaging.
Dr. Patrick Tracy, Medical Director of Ailesbury Clinics in England, Ireland and the Middle East, has released the results of a randomized comparison study of two fractional CO2 lasers on half of the face in 23 patients.
Two devices were used in a study to evaluate the elimination of signs of photoaging: UltraPulse®; ActiveFX™ (Lumenis Ltd.) and Deka SmartXide DOT™ (DEKA Srl).
Procedures were performed under local anesthesia with 2% lidocaine with epinephrine, AneStop® surface anesthesia; 5 mg in situ and Valtrex 500 mg twice daily for 8 days. After the procedure, patients received a questionnaire, as well as codeine with paracetamol on demand.
Key parameters for studying the effects of fractional CO2-lasers:
- subjective assessment of the patient's skin condition on a five-point Dover scale at 2, 4 and 12 weeks after the procedure;
- assessment of the skin condition (presence of wrinkles and superficial vessels, roughness, pigmentation level) during re-epithelialization;
- Assess the severity of erythema and the presence of other side effects, including the development of infections.
According to histological data collected after 7 months, the laser beam of both devices penetrated to the same depth, but ActiveFx showed better results than SmartXide due to the gradual increase in the rate of neocollagenesis.
92% of patients in the ActiveFX group rated the skin condition on the treated half of the face as significantly improved. In the SmartXide group, the number of satisfied patients was 84%.
Although both lasers showed similar results at the beginning of the follow-up period, a significant difference began to appear at the third month after the procedure. It was noticed that after the procedure on ActiveFx, the process of new collagen formation was much more active. The author of the study recommends the use of the ActiveFx laser for the treatment of more serious aesthetic defects. UltraPulse® ActiveFX™ 6 times more powerful and 4 times more deeply penetrating of all existing CO2 lasers. The device is approved for the treatment of 34 different dermatological indications, has an optimal ratio of ablation and coagulation and can be adapted to a wide range of aesthetic and surgical tasks.
