LASH and BROW Dual System




This hardworking duo is ultra-restorative and efficacious; the groundbreaking serums help reduce shedding and loss while supporting the body’s ability to anchor the lash and brow follicle to the root system, rejuvenating elastin while delivering stronger, thicker and longer looking lashes and shapely thicker looking brows. Suitable for all skin types, genders and age. Bundled together to bring you special savings.

Each tube 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.

BROW Shape Altering Serum

  • Apply AM & PM
  • Start with clean, dry eyebrows.
  • Use the applicator brush to stroke the serum onto the eyebrows (or sideburns, beards, or goatees) using a short, vigorous motion directly on the hair follicle and/or the skin where hair growth is desired.
  • Redip brush to collect more serum as needed.
  • When starting a new tube, gently shake the container prior to opening.

  • The serum can be applied under makeup with little to no wait time. We don’t recommend using it after a brow pencil or gel, as this will dirty the applicator.

    The BROW serum has a clear consistency. Gently shake the tube prior to use. Pull the applicator straight out (not at a diagonal). Pumping the wand will not increase the amount of serum on the brush. Note, the brow brush is made of vegan-material and product will not goop. This is by design. The custom tube is filled to capacity for 4-5 weeks of use, twice daily.

    For best results, use consistently. Store in a cool area, away from sunlight and heat. Do not freeze. Not intended for direct contact with eyes. If this should occur, rinse thoroughly with cool water.

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.

The BROW Shape Altering Serum and HAIR Vibrant Scalp Treatment may take more time, but clinical studies show a 60% improvement in brow thickness/size and a 50% improvement in hair thickness by week 12!  To achieve the best results, it is recommended to apply the product in areas where there is less hair, twice a day (morning and night). However, some areas may take longer, up to six months or more, to improve. Unfortunately, if the hair follicle is damaged beyond repair, new growth may not be possible.

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.

It works

All and all took about 7 weeks to notice anything but when it did it was a huge difference in length and thickness . I did notice my eyelashes did get darker. Can’t say much for eyebrows. I didn’t use the serum on them. My eyebrows are good to go .

I have eyebrows again!

As I’ve aged my eyebrows have gotten thinner and lighter to the point where they were nearly non-existent but since I started the serum they are thicker and darker than they ever were before.

Shaved off 10 years!

I started using Nulastyn ahout 4 months prior to my wedding. I had NO idea how much I would love this stuff! I look so much younger with thicker brows and for the first time I can go outside without mascara (PS I am wearing mascara in this pic but not a lot). I’m even getting growth in the tails of my eyebrows which is definitely making a difference in my face. I’ve just let them grow wild and will go soon to get them professionally shaped before my wedding. Once the brows grew in, I’ve been using the lash applicator to fill in any brow spots, and applying for my lashes once every few days. I’ve gotten compliments from customers old and young, and my fiancé admitted I look different in a good way but he can’t tell exactly how. So happy I started this product and wish I had ages ago!

It works!

It took about 8 weeks to really see results using twice daily but I now have the darkest, thickest eyebrows of my life! Before this, I was considering microblading. I've also regained my eyelash length and thickness. I have light brown eyelashes so I still wear mascara but it is easier to apply/holds the mascara so much better now and looks amazing. I experienced some eye dryness in the morning when I was using 2x daily but seems very minimal now and worth it in my opinion. I 100% recommend both products and will continue using to maintain.

This Stuff Works!

I started using Nulastin lash and brown serums ten months ago and had amazing results in a matter of two months. I now apply it once a day to maintain the growth. My lashes are longer and fuller than they have ever been and my brows have even grown over a surgical scar in one eyebrow where no hair has grown in 62 years! I had a professional makeup artist tell me how beautiful my lashes were and I told her what I’ve been using. I think you have a new customer.

Karin D.
Sparse to full brows!

I had very sparse brows for years due to a medical condition. After just 6 weeks of using Nulastin my brows went from sparse to full! It has made such a difference in my appearance. My eyebrow waxer has even started to recommend Nulastin over the product that she used to recommend based on my results. If you are thinking about it, just try it!
