Achieve consistent, high-performance results by following these professional guidelines:
This is a precision tool for professional lash artists only. Always keep out of reach of children. Elevate your service with the engineered solution for flawless, efficient applications and lasting client satisfaction.
Yes, this glue is strictly for professional use only. Its half-second drying time requires advanced skill and precision to apply safely near the eye area. We strongly recommend proper training and certification for anyone using this product.
"Water & oil resistant" refers to the cured bond's durability, but the glue requires 24-48 hours to fully cure and reach maximum strength. For the best retention of 4-6 weeks, advise clients to avoid steam, oil, and water exposure for the first 24-48 hours after application.
Cyanoacrylate glue begins to cure and thicken upon exposure to air. Changing the glue dot every 30 minutes ensures you're working with the optimal viscosity for a strong bond. This practice is essential to achieve the advertised 4-6 week retention.
Always close the bottle tightly and store it in a dark, cool place like a drawer. Even with perfect storage, once opened, the chemical reaction with air moisture begins, so the product should be used within 30 days for best performance.
Yes, it contains black pigment to blend seamlessly with most lash bands. When applied correctly by a professional, residue should be minimal; any excess should be cleaned from the lid immediately before it dries.
"Japanese glue" signifies a high-quality formulation associated with precision and innovation. This particular product features advanced, low-fume technology that enables the exceptional half-second dry time, enhancing comfort for both the client and the artist.
Humidity directly controls drying speed: too low can slow curing and weaken the bond, while too high can cause overly fast drying, stringing, and reduced working time. For optimal results, we recommend using a hygrometer and adjusting your room's humidity to stay within the ideal range.
The yield depends on your technique and adherence to the 30-minute dot change rule. When used correctly by a professional, this 5ml bottle is a standard size designed to complete multiple full sets and fills.
