NULASTIN eyelash 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 lashes.

Start with clean, dry eyelids.
Use the applicator to apply a thin line of LASH Follicle Fortifying Serum to the base of the upper lash line from inner to outer corner, after skincare and before makeup application.
Apply twice daily, AM & PM
Do not apply to the lower lash line.

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. To reduce the risk of irritation or other side effects, do not apply to lower lash line. 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 lashes, enhance lash color, and increase visible lash 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 lash density, length and volume.
Biodesigned Keratin: A biomimetic, full length keratin protein that helps supplement keratin where it is most needed to strengthen the lash 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, longer lashes.
Biodesigned Isopropyl Cloprostenate: A biomimetic, analog of prostaglandin included at a specific concentration to safely and effectively support natural lash growth for visibly enhanced eyelashes.

NULASTIN LASH Reviews

Non-irritating results!

I'm so thankful having found Nulastin. I used several other lash products, and without fail, my eyes would become unbearably irritated. Peeling skin on my eyelids, constant watering. Thank for for making an effective AND safe product!

Very good product, it’s working great!

Lashes longer and fuller

It works! After 5 weeks, I’m seeing results. Might do the hair serum!

Works wonders!

I’ve been using both the brow and lash serum for about a year now, and I love both so much that they will stay a constant part of my skin/hair care routine forever! It’s amazing how much a stronger brow enhances face shape, and my lashes have never been longer. Love!!!

Great results

My daughter actually noticed the change in my brows. It took a few months for the results to really show up. I got some really great advice from one of the consultants and gave me the actual time line that is needed to see results. I had some issues with my first tube as it did not really have product in it but this was corrected by the company sending me a new tube immeditately,

Best lashes ever

I have been using this brand after using different ones. This is the best. It really works. No irritation.
Great product.

Frequently Asked Questions

Got a question about NULASTIN® LASH 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.

NULASTIN® LASH serum is highly recommended for individuals with eyelash extensions and lash lifts. Lash extensions and lifts can wreak havoc on your natural lashes. We’ve found that daily application of our LASH Follicle Fortifying Serum helps maintain the integrity of your natural eyelashes. There is no evidence that our serum will fade tinted lashes or tattoos.
