A patented intravaginal ring designed to deliver continuous, controlled release of active and functional ingredients for up to seven days.

Women have long been underserved by products that are short-acting, inconvenient, or poorly optimized for female physiology. Many oral formats lose the majority of their active ingredients due to digestion and first-pass metabolism, limiting effectiveness and requiring higher or more frequent dosing. The LIV-Rin platform offers a fundamentally better alternative.

By enabling direct absorption through highly permeable vaginal tissue, LIV-Ring has the potential to deliver active and functional ingredients more efficiently and consistently. Its weekly, controlled-release system is designed to work with her biology—providing steady, predictable diffusion instead of the peaks and troughs associated with single-use or daily-use products.

The familiar, discreet format requires minimal effort, reduces daily burden, and enhances adherence. For women seeking solutions that are practical, comfortable, and science-driven, the LIV-Ring represents a meaningful step forward: a platform built to provide reliable, long-lasting support across a range of women’s health needs.

It’s not just a new delivery system—it’s a smarter, more biologically aligned approach to delivering active and functional ingredients to address important unmet needs in women’s health.

VR101, the first product using our platform, is FDA-cleared as a medical device for improving vaginal dryness and comfort.

The LIV-Ring platform is based on an intravaginal ring delivery system that features a reservoir design where an active or functional ingredient can be loaded into the reservoir and gradually diffuse through a polymer matrix, providing consistent, steady-state release over the course of days or weeks.

The LIV-Ring platform is intentionally designed with flexibility in mind, capable of incorporating a wide range of active and functional ingredients. This versatility enables a pipeline of potential future applications that extend well beyond our initial focus areas.

Emerging opportunities include pelvic pain and wellness, pain management, pH balance optimization, microbiome support, and additional women’s health categories. Each potential application will advance through a structured development process and a rigorous review to ensure safety, efficacy, and clinical credibility.
