Background: Consider A plethora of noninvasive approaches has been developed in recent years for facial rejuvenation. Energy‐based devices have been one of the most popular treatments for reversing and preventing signs of facial aging such as fine lines, wrinkles, ptosis, and photoaging..
Aims: A new technology (RecoSMA) for skin rejuvenation based on acoustic‐interference method using Er:YAG laser (2936 nm) equipped with a special module that targets both the dermis and the superficial musculoaponeurotic system (SMAS) was recently demonstrated to be safe and effective in facial rejuvenation.
Patient/Methods: In this follow‐up prospective study, the clinical effects of RecoSMA treatment on skin structures and SMAS were evaluated with ultrasound and histological analysis, at 30 and 90 days posttreatment.
Results: Treatment with RecoSMA was shown to result in a significant increase in thickness of the epidermis, dermis, and SMAS layer, while levels of collagen I, III, and IV were shown to be elevated at 90 days posttreatment.
Conclusion: Collectively, data show that treatment with RecoSMA laser has a profound biological effect in stimulating and reconstructing the elastin/collagen framework necessary for preventing facial aging.
