Despite being a common concern, there are very few minimally invasive treatments targeting neck skin laxity (NSL) reported in the literature. To assess the efficacy of hyperdiluted calcium hydroxyapatite (hy‐CaHA) for the treatment of NSL, according to the NSL scale, and to estimate safety. Twenty patients showing NSL were treated with hy‐CaHA 1:2. To evaluate the efficacy of hy‐CaHA treatment for NSL, pictures of treated subjects were collected before and 3 months after treatment and graded according to the NSL scale, and T‐student's test was applied to estimate differences. Hy‐CaHA for the neck was effective according to the previously unreported NSL scale (p < 0.001) and safe. There were no major adverse events reported. This study supports the efficacy (according to the NSL scale) and safety of hy‐CaHA (1:2) for NSL. Our results also highlight the utility of the newly developed NSL scale, being a useful tool to evaluate the level of NSL before treatment and to measure the outcome. [ABSTRACT FROM AUTHOR]
