The goal of this interventional clinical investigation using Genefill Contour® CE marked device outside of its indication is to compare with other hyaluronic acid device already marketed for labia majora augmentation in women with labia majora hypotrophy/atrophy.

The primary objective is the evaluation of the safety of Genefill Contour®. The secondary objectives is effectivenes of the investigational device (improvement of patient´s symptoms, patient´s satisfaction, sexual function & pain during injection).

Participants will come to a total of 8 visits (including 2 phone calls) over a period of 12 months. Participants would be enrolled in Genefill Contour® or comparator group.

An ancillary study would be conducted in a cohort of participants evaluating the increase in volume and distance between labia after HA injection
