Researchers have uncovered the mechanism by which certain skin rejuvenation techniques work. In particular, therapies such as laser therapy, microneedling, and facial abrasion cause temporary damage to the skin that release self-noncoding double-strandedRNA (dsRNA) molecules. These, in turn, stimulate regeneration.
“Our technology allows us to scan tissue quickly, and when we see a suspicious or abnormal cell structure, we can perform ultra-precise surgery and selectively treat the unwanted or diseased structure within the tissue—without cutting into the skin,” said Yimei Huang, co-lead author of the study
The survey also uncovered the top five treatments among the survey participants. The percentages of respondents who have had previous treatments include: ultrasound, laser, light and radiofrequency treatments for smoothing skin (57%), body sculpting (57%), microdermabrasion (51%), laser hair removal (48%), and injectable wrinkle-relaxing injections (47%).
