Background The eyebrow area is a clinically critical district due to the anatomical complexity and the propensity to aging-related atrophy. Hyaluronic acid fillers have been proposed to recover the dermal volume of the facial and lips regions. Aim The aim of the present investigation was to evaluate hyaluronic acid fillers enriched with glycine and proline for the treatment of eyebrow augmentation. Methods A total of 15 healthy patients were treated with eyebrow augmentation procedure. The distance between mid-bipupil to lateral eyebrow and mid-eyebrow to the medial eyebrow was measured before, immediately after treatment and at follow-up of 6 months. Results The healing period was uneventful, and no evidence of inflammation or swelling associated with the treatment was reported. No macroscopical alteration was reported in the surrounding tissues with no evidences of visible wheals or lumps in the treated sites at the follow-up. Before treatment, the angle was equal to 9.32 ± 0.2°, while after treatment it was 11.21 ± 0.4° ( p  < 0.01); after three and 6 weeks, it was, respectively, 10.66 ± 0.2° ( p <0.05) and 10.02 ± 0.3°( p  > 0.05). Conclusions The study results suggest that the hyaluronic acid fillers enriched with glycine and proline treatment resulted as being a useful procedure for augmentation, contour and volume definition and elevation of the eyebrow region with a high-level aesthetic result.
