Frequently Asked Questions
Q: Why is 0.3 seconds faster than 1 second? Isn't 1 second already fast?
In lash extension application, every second of dry time is a window of micro-adjustment. At 1 second, a lash artist still has a brief moment to shift placement. At 0.3 seconds, the bond is set the instant the lash touches. The gain is speed, but the requirement is precision. Lash artists who have completed 1,000+ sets have the muscle memory to place accurately at contact. For everyone else, 1 second is the safer, more forgiving window.
Q: How does 10-week retention compare to other professional adhesives?
The most popular professional adhesives on the market claim 6-8 weeks retention tested under ideal lab conditions. Insider delivers up to 10 weeks because it was developed for real salon environments by a working lash artist and esthetician, not a laboratory formulator.
Q: What happens if I use Insider without enough experience?
At 0.3 seconds, there is no recovery time after placement. Lash artists who use Insider before developing precise, confident placement technique risk bonding extensions at incorrect angles or sticking lashes together. This is why we recommend a minimum of 2 years or 1,000+ sets. Start with Expert (0.5-1s) and move to Insider when your placement is automatic.
Q: Is Insider safe for clients with sensitivities?
Yes. Insider is 100% latex-free and formaldehyde-free with low fume output. For clients with heightened sensitivity, use with Beauty Power Lash Bonder immediately after application to seal the bond and eliminate residual fumes in seconds.

I’ve been in the lash industry for years, and I have to say, this is one of the best adhesives I’ve ever used. The bonding power is amazing, and it holds up in various weather conditions. Whether my clients are in humid or dry environments, their lashes stay flawless. I’ve been using this adhesive on clients with very oily skin, and it’s holding up like a dream — no sliding or slipping at all! It’s truly a game-changer for retention, especially for clients who need that extra hold. If you’re serious about providing long-lasting results, this is the glue to go for!Ps: Incredible tweezers from this brand too!
As a professional lash artist with years of experience, I highly recommend this glue!The drying time is perfect for me. It dries very quickly, which helps me to work faster without waiting too long between lashes. This is very helpful when I have many clients in a day. It also has very strong retention, holding the extensions in place for a long time, up to 6-8 weeks, which my clients love!One thing I really like is that it has low fumes. My clients have not complained about any burning or redness, which is a big advantage.For professionals, I believe this is a must-have for your lash tool kit. It is reliable, and the quality is very consistent, so I trust it on all my clients. Just make sure to store it properly in in the thermal package that comes with the kit for the best performance.Definitely recommend!
I've struggled to find a lash adhesive that works well with my clients who have sensitive eyes, but this one is perfect. It’s gentle, yet the hold is incredibly strong. I’ve received so many compliments from clients saying their lashes last longer than with previous adhesives I’ve used. I had one client who used to complain about redness and irritation with other adhesives, but with this one, her eyes are completely calm, and her lashes last for over four weeks! Definitely a product I’ll be buying again and again — it's a total game-changer for anyone dealing with sensitive clients.
The best adhesive I've ever tried! I tried many of them and finally found the best one. Perfect consistency, speed and retention. My clients retention is better than ever. Even after 8 weeks they will arrive with a sufficient number of eyelashes. That adhesive is not capricious and works great with any temperature and humidity. 4 weeks retention on video WOW!!!
