Thirty Asian women aged 40-55 with Fitzpatrick III-IV skin received three needle-free jet sessions of self-crosslinking hyaluronic acid at four-week intervals. At week 12, 3D wrinkle and texture measures improved across malar and pericommissural regions; investigator severity fell from 7.28 to 4.32, and 60% reported moderate-to-marked improvement. Treatment reactions were mild and transient. The single-arm design cannot separate treatment effects from time or expectation.
Key findings
- 3D imaging and investigator ratings improved by week 12. • Sixty percent reported moderate-to-marked improvement. • Reported treatment reactions were mild and transient.
Why this matters globally
Needle-free delivery may improve superficial dispersion and acceptability, but comparative controlled trials are needed before claiming superiority.

Limitations to consider
The 30-person single-arm, unblinded study lasted 12 weeks; durability, other skin types and rare adverse events remain unknown.
