Conventional hyaluronic acid (HA) formulations vary in their ability to achieve uniform superficial dermal dispersion and sustained tissue effects, and needle injections may lead to inconsistent depth and localized pooling. This study evaluated changes in facial skin texture and fine wrinkles following delivery of self-crosslinking HA formulation containing N-hyaluronoyl 5-hydroxydopamine through a needle-free jet injection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Thirty women aged 40\u201355 years with Fitzpatrick skin types III\u2013IV and visible fine wrinkles underwent three treatment sessions at 4-week intervals.
