NULASTIN BROW serum features Elastaplex® Technology, a proprietary blend of biodesigned proteins and signal peptides formulated to boost elastin—the protein that anchors hair. This breakthrough technology helps minimize fallout and premature shedding by fortifying follicles at the root, resulting in visibly thicker, fuller looking brows.

Start with clean, dry eyebrows.
Use the applicator to apply BROW Shape Altering Serum in short, upward brush strokes onto the eyebrows, after skincare and before makeup application.
Apply twice daily, AM & PM.
The custom spoolie applicator is designed with synthetic bristles to pick up and deposit the ideal amount of serum for each brow.

WARNING: Use only as instructed. For external use only. This cosmetic contains a small amount of Isopropyl Cloprostenate, an analog of prostaglandin. Avoid getting serum in eyes; in the event of direct contact, rinse with cool water. If redness or irritation occurs, stop using the product. If irritation or redness persists, consult your doctor. If you tend to have sensitivity to products, we recommend a patch test before use. Do not use if you are pregnant or nursing. If you are being treated for any eye or serious medical condition, consult your doctor prior to use. Keep out of reach of children.

Biodesigned Signal Peptide [Myristoyl Pentapeptide-17]: A biomimetic, five amino acid peptide that supports active melanocytes & keratinocytes to strengthen eyebrows, enhance brow color, and increase visible brow density.
Biodesigned Elastin [sh-Polypeptide-50]: A biomimetic, full length elastin protein that helps supplement elastin where it is most needed to anchor the lash follicle– minimizing fall out and maximizing visible brow density, fullness and shape.
Biodesigned Keratin: A biomimetic, full length keratin protein that helps supplement keratin where it is most needed to strengthen the brow hair follicles.
Biodesigned Hepatocyte Growth Factor [sh-Polypeptide-62]: A biomimetic, full length signal protein that collaborates with natural growth factors to support anagen (growth) and catagen (transition) phases to promote visibly thicker, fuller brows.
Biodesigned Isopropyl Cloprostenate: A biomimetic, analog of prostaglandin included at a specific concentration to safely and effectively support natural brow growth for visibly enhanced eyebrows..

NULASTIN BROW Reviews

It works

This serum works for growing the eyebrows thicker.

This Stuff Works!

As a result of some bad tweezing decisions in the nineties, I had a half eyebrow on my left side. Think Mr Spock. I’d tried other products to make it grow in and nothing worked so I’d resigned myself to drawing the other half of my eyebrow every day. I saw the ads for Nulastin with the before and after pictures and I decided to give it a try. Now, it doesn’t work overnight but in about 12 weeks my eyebrows were thick and completely grown in. I then went to a brow tech and she tweezed my brows into beautiful arches. Success! No more Mr. Spock and I can put away my brow pencil!

Actually works!

This is an amazing product. It actually works! You will be shocked at how quickly you see your eye brows grow!

So surprised!

Wasn’t really expecting to see results on my right eyebrow. I fell last year and had a gash across my right eyebrow, requiring stitches. That leaves scar tissue. But I am seeing hair growth in the scar area! I am impressed.

It’s a sure shot

Totally guaranteed to have a transformative appearance

Great After Medical Treatment

I had a pre-cancer area of my eye brow treated with cryotherapy (doctor applies liquid nitrogen to freeze and kill the cells) several times over several months. It also caused a lot of hair loss in the area. After treatment I started using the brow serum to try to regrow my eyebrow. I was amazed at how quickly and effectively it worked! I love this product and am now a user for life!

Frequently Asked Questions

Got a question about NULASTIN® BROW serum? The answer may be right here or you can check our full list of FAQs.

All of our products are designed for ease of use and can be applied under makeup with little or no wait time. For best results, use twice daily to clean, dry eyes and/or skin.

Consistency is the key to lasting results, but don’t stress out if you skip an application. If you do miss a few days, just start back up and use daily as directed. We don’t recommend trying to “catch up” with a loading dose or duplicate applications for our LASH, BROW, or HAIR products. Our skin care products can be used as much as desired—multiple times daily.

During the 12-week clinical study, no subjects experienced adverse events relating to the BROW Shape Altering Serum.
