Retention Improving Booster & Superbonder - samples



Ongoing problems with retention? Clients' lashes don't last? Try our bestselling products - Booster and Superbonder in 2ml sample size bottles. Both products designed to solve the biggest problem of the lash artist - retention issues. 

Retention & Speed Booster is a multi-functioning product that will enhance your treatment as it increases retention AND the speed of work. 

Due to its very high alkalinity, Retention & Speed Booster helps to gently open the hair cuticles. This enables more glue to stick with the extension and the natural lash thus increasing retention.

If you apply it to the strip of extensions, it will help you to make your fans much faster and easier - as glue won't "run up" along the "leg" of the fan, so your fans won't close and stay nicely opened instead. Do not use Booster on Easy Fanning lashes! 


How to use

To increase the retention, apply Retention & Speed Booster with a micro brush on natural lashes, after  cleanser  and  primer  to slightly open hair cuticles and increase the surface for better grip and adhesion.


To increase the speed of the treatment, apply Retention & Speed Booster with a micro brush on the strip of the extensions in the box or on the lash palette to prevent the fans from closing during the "fanning". 


Retention Superbonder adds elasticity to the adhesive; the additional flexibility ensures the bonds don't break as easily, therefore resulting in better retention.

It also instantly polymerises the glue, without shock curing. It locks in the fumes from the adhesive and with the fumes contained, irritation and sensitivity are significantly reduced. Because the bonds have been sealed, the lashes, therefore, are instantly safe to get wet. Yourself and your clients will no longer have to worry about the rain, having a shower or going to the gym!

  1. Once you've completed the eyelash treatment, squeeze 1 small drop of Retention Superbonder onto a  microfibre brush  and carefully apply at the bottom 2-3mm of the eyelash set (adhesive area) making sure the product doesn't get into client's eye. 
  2. Allow the product to dry for 1-2 minutes. 
  3. Remove the eyepatches and let the client open their eyes. 

For the best results, use both - Superbonder and Booster. 

Superbonder and Booster work with any professional cyanoacrylate based eyelash extensions adhesives.

Does the job

I was always sceptical about trying something like this but thought why not! I am so glad that I did. I lose my lashes all the time and often go for weekly infills. I am now on week 2 and think there’s potential to last another 10 more days before my next infill. This Superbond is excellent x

Hi Sabrina!

Thank you so much for this AMAZING review

We're over the moon to hear you love our Superbonder !

Doesn’t work out for me


Great addition to a lash set on rainy days 👍

worth buying!

Both are definietly worth buying, since I tried small size, I'm now buying full size bottles as my retention improved so much 💕


Happy with my buy! I got both samples, great way to try before committing to full bottles. Definitely noticed an improvement in how lashes are lasting, and I don't have problem with closing fans anymore.
