Safe and effective Skin Rejuvenation and Pigment Removal performed with Pico Toning by a novel 1064/532nm Picosecond Laser.

This article shows a novel, minimally invasive laser method for skin rejuvenation by creating isolated microscopic lesions within tissue below the epidermis using laser induced optical breakdown (LIOB). Using a well-researched technology, wavelengths of 1064/532nm focused near-infrared laser pulses are used to create optical breakdown in the dermis while leaving the epidermis unharmed, resulting in cavities due to plasma formation. This stimulates a wound healing response and leads to stimulation and neocollagenesis terminating in results of skin rejuvenation such as improvement of laxity, colour, and improvement in the appearance of pores. A retrospective trial with analysis of in-vivo, non-interventional treated human skin samples successfully showed the safety and effectiveness of the treatment; microscopic in LIOB and macroscopic in edema and erythema. Treatments can be performed by minimal to no downtime and mild to no side-effects with no topical anesthetics needed. The non-interventional in-vivo results shown by confocal laser microscopy (LC-OCT), showed evidence of microscopic cavities and new collagen formation around the vacuoles. Conclusion: This method is a safe and efficient alternative to more invasive procedures by minimal to no social downtime and mild to no side effects. [ABSTRACT FROM AUTHOR]
