Lashes and brows

I’ve been using the lash and brow serums for little over a month. My eyebrows were almost nonexistent. Now it’s so cool to have my eyebrows back; but the most amazing thing is that they’re dark brown and not grey! My eyelashes are so long and pretty again! I’ll use this stuff forever! I love it! Thank you Nulastin 😊

Great Product

I bought the lash and brow duo about 2 months ago and I can’t tell how happy I am! I am a active 67 year old! I noticed that my lashes and brows were thinner than in my younger years especially my lashes! This product worked wonders and I will definitely order more!!


I have tried other serums in the past but nothing gave me the results that nulastin brow and eyelash serum has done. I started using it two months ago. Within a month I could see my eyelashes were longer and my brows started filling in. Also my brows are looking darker and my eyelashes even have a natural curl to them again. My ethetician also noticed the difference I am just starting the scalp treatment and hopefully will see a difference in the future.

Amazing results

I was skeptical but hopeful that this would help my ever fading eyebrows. I had tried latisse but it made my skin itch and I wasn't seeing the results I wanted. With aging, I was noticing the lower half of my eyebrows thinning a lot. It was especially noticeable in photos. I saw an ad for Nulastin and thought I would give it a try after reading the reviews. I can tell you that I am SOLD! My eyebrows have completely filled in and have come in dark (not grey). There is no allergic reactions and I am beyond thrilled with the results on both my eyebrows and eyelashes. Thank you Nulastin!!

Eyebrows thumbs up, but....

I LOVE the way my eyebrows are growing using the serum. I notice new growth and they are longer. Unfortunately the eyelash serum burns my eyes no matter the amount I use. I will repurchase the eyebrow serum but not the eyelash.

Amazing !!!

I have use Nulastin for a little over a month. The first month I applied the product two times per day, now I only use it once a day because my brows and lashes are beautiful. The wow factor is crazy when I apply mascara. My brows have filled in and are no longer white in spots. I can't say enough about these products. Worth the $.
