NULASTIN LASH and BROW serums feature 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 and brows.

Apply both serums twice daily, AM & PM, after skincare and before makeup application.
Start with clean, dry eyelids & eyebrows.
Apply a thin line of LASH Follicle Fortifying Serum using the applicator to the base of the upper lash line from inner to outer corner.
Do not apply to the lower lash line.
Apply BROW Shape Altering Serum with the spoolie applicator in short, upward brush strokes onto the eyebrows.

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 eyelash and eyebrow color, and increase visible 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 & brow follicles– minimizing fall out and maximizing visible density and volume.
Biodesigned Keratin: A biomimetic, full length keratin protein that helps supplement keratin where it is most needed to strengthen the eyelash & eye brow 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 lashes & brows.
Biodesigned Isopropyl Cloprostenate: A biomimetic, analog of prostaglandin included at a specific concentration to safely and effectively support natural growth for visibly enhanced eyelashes & eyebrows..

NULASTIN Reviews

Brow and lash duo

I’ve been using the brow and lash duo twice daily for the last month. Things are just starting to grow I believe I’m receiving from chemo that took my hair and brows and lashes 3 years ago in addition to being in my mid 60’s Where my hair is retreating from growth.
In a month I may see more progress
I love the lip balm that seemed to cure a two month lip split thank you.

It works

Brows are growing back and darker

Love this duo!

I started using Nulastin after I went through chemo and had lost all my hair -- brows and lashes included. I use the products religiously and my lashes are longer then they ever were before cancer, and I have full eyebrows now. I only had a half a brow previously and had to wear eyebrow pencil every day.

Only non prescription lash serum that works!

I’ve tried all the leading non-prescription lash and brow serums and nothing else works like this. Worth the money!

So far so good

It’s been a few weeks and I’ve noticed some new growth on previously sparse parts of my brows.

Quickest results!

I’ve used other lash serums and this one has given me the best, quickest results for the price by far!
