A novel method of facial rejuvenation using a 2940-nm erbium:YAG laser with spatially modulated ablation: a pilot study

The objective of this study was to determine the efficacy and safety of a novel method of facial rejuvenation using a 2940-nm erbium:YAG laser with Spatially Modulated Ablation (TM). A pilot study was performed in 16 women with moderate to severe signs of facial aging relative to chronological age, who underwent two treatment sessions with an Er:YAG laser coupled to the RecoSMA (TM) technology (Linline, Minsk, Belarus). The whole face was treated in all patients. Clinical efficacy, tolerance, adverse effects, complications, and histological changes due to the treatment were evaluated. Clinical photographs and biopsies were taken before treatment and 3 months after the second treatment session. All patients completed the study and presented no significant complications. Histological changes in the epidermis and dermis as a result of treatment were found. Fine lines, wrinkles, and overall facial aging improved significantly (p < 0.0001). The mean reduction of fine lines and wrinkles was 59 % (r = 40-75 %). The mean improvement of overall facial aging was 74 % (r = 55-90 %). After showing the patients the comparative photographs before and after treatment, 75 % of women stated that they were satisfied or very satisfied and would recommend the treatment. Preliminary results show an excellent safety/efficacy profile for this novel technology, which, based on observed results, can be considered to have advantages over other methods of facial rejuvenation with lasers.
