hyaluronic acid + polycarbophil

**hyaluronic acid + polycarbophil** is a combination of two polymers, used primarily in vaginal moisturizing gels and topical formulations for the treatment of vulvovaginal atrophy, dryness, and related symptoms. *Hyaluronic acid* is a naturally occurring biopolymer with strong water-binding and viscoelastic properties, facilitating hydration, tissue repair, and scaffolding for cell proliferation. *Polycarbophil* is a synthetic polymer notable for its bioadhesive and mucoadhesive properties, enabling prolonged contact and water retention on mucosal surfaces. The combination provides sustained moisturization, improved vaginal health indices, and optimal safety profiles for vaginal dryness, with both ingredients acting locally through physical hydrating and film-forming mechanisms rather than systemic pharmacological activity[1][2][3][4].
