LASH Follicle Fortifying Serum




A game-changing serum that helps reduce shedding while supporting the body’s ability to anchor the lash follicle to the root system, rejuvenating elastin while delivering stronger, shinier, thicker and longer looking lashes. Designed with a genetic code, making it suitable for all skin types.

Each container lasts approximately 4-6 weeks (or longer if reduced to once daily).

LASH Follicle Fortifying Serum

  • Start with clean, dry eyelids.
  • When starting a new tube, shake the container prior to opening.
  • Use the applicator brush to apply a thin line of serum just above the lash line on the top lid (inner to outer corner).
  • We do not recommend using the serum on the bottom lashes, as this could lead to irritation in the eye area.
  • Apply twice daily (morning & evening).
  • Reduce usage to once daily when you’ve achieved your ideal look.

  • Use only as instructed. For external use only. Do not get 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 eyes. 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.

Frequently Asked Questions

Most of our customers receive their first unsolicited compliments within a few weeks of using NULASTIN. It should be noted that results may differ from person to person and not everyone will have the same response to the product. The speed with which you notice results is dependent on several factors such as the consistency of product application, age, gender, genetic predisposition, environmental conditions and other factors.

With the LASH Follicle Fortifying Serum, you may start noticing some changes within a few weeks of using it. Your lashes may feel more luxurious, and they may hold mascara better. After six weeks of consistent use, you may observe even more significant changes, such as an increase in length, width, and density of your lashes. According to a clinical study completed in July 2023, the results of using the serum doubled between week 6 and week 12.

With all of our products, timing is different for everyone. Your lashes, brows, and hair grow in stages. For lashes and brows, the cycle lasts 3-4 months. Scalp hair can take longer. 

— The 1st stage (anagen)

When your hair grows a little every day (30-45 days).

— The 2nd stage (catagen)

The transition or regression phase — when your hair follicles shrink, allowing the strands (bulb) to extend toward the surface (2-3 weeks). 

— The 3rd stage (telogen)

The resting phase. Your hair bulb is inactive, and the hairs eventually fall out (Around 100 days). 

— The 4th stage (late telogen or exogen)

Reassembly. This is where new follicles are formed. Think of it as the reawakening process before the hair starts back into the growth phase.

We are proudly 100% made in the USA. As a Boulder, Colorado company, we also take pride in the fact that we manufacture and endeavor to source locally. Our workforce supports American jobs within the community.

All 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.

Big change in just 9 weeks!

I notice length most but also see some thickness improved. Sometimes I feel a bit of stinging/burning after application but it resolves in just a few minutes.

Absolutely worthy

My lashes are visibly longer and thicker after 2 months of using this product.
The first photo shows my lashes with 3 layers of mascara, and the second picture shows my lashes visibly longer and thicker without any máscaras on them.

Great results

I was definitely skeptical. I’ve tried natural lash growth serums before, always too oily and made my lashes too soft to curl. I ordered the double pack on Black Friday, it’s now February 8th(have been using for 2 months) and still on the first bottle and my lashes look amazing. I started out using twice a day for the first month or so, then just in the evenings. They definitely got long fast, they have gotten thicker too over the past month. I don’t have a b4 pic, but here is after with no mascara. They almost look like fake lashes with my mascara on. Also they look better than the picture, I don’t know why it’s so hard to get a good picture of your lashes.

My lashes are so long now! I have used many products but I have found my product in Nulastin! I currently use Nulastin for my lashes and I love the results. My friends ask me if I’m wearing false lash extensions and I told them NO. I used Nulastin!!!🥰

Results with No Side Effects

I’ve used Nulastin Lash Enhancer for over a year with great results. I’ve tried the prescription product with great results but got red eyes with it. And it was much more costly. Nulastin gave me results with no red eye!

Lashes & Brows are poppin'

I just turned 58 (yikes) and wanted to feel beautiful again. Often when you hit a certain age; hair thins, eye brows disappear, eye lashes either go gray or are short and sparse. Now, I have dark brown eye lashes and eye brows and this was after 6 weeks. Can't wait to see my future picture. I feel more feminine and have more confidence and don’t use use lash primers anymore. Don’t wait to buy, the sooner you buy the sooner your lashes and brows are growing. Love, Love, Love this product!

**the redness around my eyes is hereditary, not this product**
