Medical-Origin Universal Lash Adhesive for Full-Performance Professional Applications

Technical Quick View: Fast 1–2 second setting time, optimised for 45%–75% humidity, with a medium viscosity for controlled placement and extra-strong retention, formulated using medical-origin adhesive technology and manufactured in the UK.

Biolash Universal Black Professional Eyelash Extension Glue – 5g is engineered for lash technicians who require one adhesive that truly performs across every application, without compromising on speed, strength, or safety. Unlike conventional “sensitive” glues that sacrifice performance for comfort, Biolash Universal delivers fast, controlled curing alongside exceptional retention, making it a genuinely universal solution for professional lash work.

Manufactured in the UK, Biolash Universal is formulated using a medical-origin bonding technology based on high-purity n-Butyl Cyanoacrylate, with over 80% surgical-grade adhesive content. This bonding technology has long been used in medical wound closure due to its reliable adhesion, clean curing behaviour, and reduced irritation profile. Adapted specifically for eyelash extension application, it provides a stable, high-integrity bond while maintaining low fume exposure during treatment.

With a 1–2 second setting time and medium viscosity, Biolash Universal offers a rare balance of speed and control. It cures fast enough for efficient volume workflows, yet remains predictable and forgiving during placement. This makes it equally effective for classic lashes, cashmere lashes, lower lashes, and all Russian volume techniques, allowing technicians to work confidently across diverse lash styles without switching adhesives.

Beyond performance, Biolash Universal is designed with long-term professional safety in mind. The formulation is hypoallergenic, latex-free, and free from HQ and formaldehyde, helping minimise cumulative exposure risks for both technicians and clients. Its bacteriostatic properties further inhibit bacterial growth at the bonding site, supporting a cleaner, more hygienic treatment environment.

Compliant with EU Cosmetic Regulation standards and developed in an ISO-certified UK laboratory, Biolash Universal stands apart as a premium, medical-logic adhesive — not because it limits performance, but because it delivers fast curing, strong retention, and full application versatility within a safer, more controlled bonding system. For professionals seeking a single, high-end adhesive that genuinely does it all, Biolash Universal earns its name.

Pro-Tips for Maximum Retention

Retention starts with proper preparation and controlled curing.
To achieve up to 8-week extra-strong retention, cleanse natural lashes thoroughly using LashArt Cleansing Foam Shampoo, followed by Retention Boosting Lash Primer to remove oils and balance the bonding surface. Finish with Retention Maximising Lash Bonder to stabilise adhesive curing, seal the bond, and support consistent, long-lasting retention across all professional lash sets.
