The Brow Serum Works!

I’ve been using this product for just over a year now, and I can honestly say I think it’s worked! Not only do I see a little bit more towards the inner parts of the brows where tweezing ruined, but the brows that I did already have also appear to have gotten darker.

Restored my brow after surgery

A few years ago I had some basal cell cancer growth removed from above my right eye brow. Then, two years later, another surgery in the same spot. A lost a lot of brow. And then, my left eye brow, in a spirit of camaraderie, decided to lose some of it's hair. Nulastin has restored both brows so that I can be in public with confidence again. Please share this with anyone you know who has had similar experiences

It works!

Can't believe how quickly this started working. Can't wait to get to 12 weeks.

Nulastin works. My eyebrows are thicker!!!

Already Amazing New Growth!

I am about 5 weeks into using this product, and I am VERY impressed at how much new growth I’ve had in that short amount of time! I overplucked as a young adult and have some patchy/thin areas that I was hoping I could fill in some more. It has really been in the past week or so that I’ve noticed a change from when I started. I’m not even done with my first bottle, so I’m excited to see what the next 7 weeks will bring! Highly recommend this product, it really works!!

Try it…

I’m about to order my second Nulastin brow serum. I’m seeing some growth and I want it to continue.
