Low Molecular Weight Hyaluronic Acid Combined with Six Amino Acids for Female Genital Well-Being: A Multicenter Prospective Pilot Study
By Fasola E, Mirastschijski U, Innab AA et al.
Genitourinary syndrome of menopause (GSM), which includes vulvovaginal atrophy (VVA) and other bothersome genitourinary symptoms, affects over half of postmenopausal women and has a considerable impact on quality of life. This study aimed to evaluate the efficacy and safety of an injectable combination of hyaluronic acid and amino acids for treating GSM-related symptoms. In this prospective, multicenter study, 84 women aged 46–60 with moderate to severe VVA confirmed by gynecological examination received three intradermal treatments at 21-day intervals, targeting the vestibule, introitus, lower vaginal wall, and labia majora. Symptom severity was assessed using a visual analog scale (VAS), while tolerability and satisfaction were evaluated via a five-point Likert scale. Quality of life was measured using the Satisfaction With Life Scale (SWLS). Assessments were conducted at baseline, after each injection, and at 3- and 6-month follow-up visits. After three months, significant improvements were noted in vaginal dryness, itching, burning, and dyspareunia (all p < 0.001). Patient satisfaction increased from 59.0% to 80.7%, and SWLS scores rose from 4.57 ± 1.76 to 6.53 ± 1.10, reflecting enhanced quality of life. The treatment was well tolerated and demonstrated a favorable safety profile. These findings suggest that this injectable formulation may represent an effective, non-hormonal option for women with VVA, particularly those who are not candidates for hormone therapy.
