In the world of lash extensions, where precision and safety are equally important, choosing the right adhesive can make or break a lash artist’s work. That’s why Lii Lash introduces UV Adhesive – Bond Beyond Limits, a revolutionary glue designed to cure instantly under UV light, work in any climate, reduce irritation, and deliver flawless retention for up to 8 weeks. You will no longer need to wait or avoid water for 24 hours for the glue to dry completely; Lii Lash UV Adhesive will dry completely and deeply immediately. More than just an adhesive, it is the promise of freedom, safety, and artistry for lash professionals. 

What is UV Adhesive?

UV Adhesive is a specialized glue for lash extensions, uniquely designed so that it does not dry in the air but only cures (hardens) when exposed to UV or LED light with a suitable wavelength (typically 365–405 nm). This technology is based on the UV curing process, a light-activated chemical reaction that creates fast and strong polymer bonds.

This means UV Adhesive gives lash artists greater control and flexibility during application, since the glue does not set immediately when exposed to air. It only bonds the extensions securely and safely once UV light is applied. UV Adhesive usually has a slightly viscous texture, is clear or lightly tinted, low in odor and fumes, and remains highly stable in all climate conditions. Some brands even claim it significantly reduces allergic reactions compared to traditional lash glues.

Why Lii Lash UV Adhesive Stands Out

Unlike traditional lash glues that depend on unstable humidity and temperature conditions, Lii Lash UV Adhesive delivers consistency and control. Here’s why lash artists worldwide are excited about it:

• Low Fume & Odorless: Gentle and comfortable for both clients and lash artists.

UV Adhesive is not only a product. It is Lii Lash’s promise: to empower lash artists and protect clients’ well-being.

The Science Behind UV Adhesive

UV Adhesive is formulated with cutting-edge ingredients to deliver both performance and safety:

• Ethyl Cyanoacrylate: is the primary bonding agent responsible for the fast-setting and strong adhesion of UV Adhesive. It polymerizes quickly upon contact with moisture, creating a durable bond between the natural lash and extension. Known for its high retention power, this ingredient is ideal for lash artists who need speed and strength in their application process. 
  

• Polymethyl Methacrylate (PMMA): Comprising 5-10% of the glue, PMMA reinforces cyanoacrylate, enhancing retention and securing the extensions in place for the long term.
  

• Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide (BAPO): is a highly efficient photoinitiator used in UV lash adhesives. When exposed to UV light, it quickly triggers polymerization, allowing the adhesive to cure instantly. This ensures faster application, stronger bonding, and safer results, while minimizing fumes and irritation for both lash artists and clients.
  

• CI 77266 (Carbon Black): Adding depth to the adhesive's color, carbon black provides a rich black color. It's a minor and the heaviest ingredient and may settle at the bottom of the bottle. 
  

This unique combination ensures a glue that cures instantly with UV light, supports all lash techniques (classic, volume, mega volume, hybrid), and minimizes common adhesive frustrations.

How to Use UV Adhesive

Before You Start:

• Use a UV LED lamp (365–405 nm wavelength).
  

• Ensure both artist and client wear protective goggles or shields.
  

• Prepare lashes with primer and consider using a super bonder for best results.
  
  

Step-by-Step Application:

1. Place a drop of glue on a glue ring or jade stone.
   

2. Dip the base of the lash extension into the glue.
   

3. Attach it to the natural lash.
   

4. Cure instantly with UV light (1–2 seconds).
   

5. Repeat until the set is complete.
   
   

Storage & Shelf Life:

• Unopened: 6–8 months

• Opened: 1–3 months
  

• Store in a cool, dark place away from sunlight
  
  

⚠️ Precautions: Never expose eyes directly to UV light. Always keep the client’s eyes fully closed and use under-eye pads for protection.

The Bigger Picture: Why UV Adhesive is the Future

Traditional adhesives have always been a compromise—fast curing but risky for sensitive clients, or stable but dependent on the environment. UV Adhesive eliminates these trade-offs.

• No waiting time. Instant curing means faster sets and happier clients.
  

• No climate stress. From humid summers to dry winters, your glue works flawlessly.
  

• No compromises on safety. Drastically reduced risk of irritation.
  
  

UV Adhesive unites performance, safety, and freedom in one breakthrough product.
