A 56-day Clinical Study on Facial Skin Rejuvenation

Clinical Study on 56-Day Continuous Improvement of 1064nm Fractional Picosecond Laser Treatment With Formulations of A Proprietary Anti-aging Complex Composition

This clinical trial aims to learn about the efficacy of MLYAAT-1002® (a proprietary anti-aging complex, MLYAAT is short for "multi-layer anti-ageing technology" ) in female subjects who have newly received the rejuvenation treatment by comparing visual clinical scores, skin attributes measurement and image analysis.

The main expectations are:

• After the 8-week continuous use of the test formulations with MLYAAT-1002® on one split-face side, the clinical manifestations and scores of photoaging improve compared to those of the control side using the placebo formulations.
• After the 8-week continuous use of the test formulations with MLYAAT-1002®, indicators of skin tone, individual type angle (ITA), CIELAB color space, pores and wrinkles improve compared to those of the control side using the placebo formulations.
