I just returned this product having recently purchased it and was so disappointed. For one, it is like water, even after shaking container, which is so small. There is barely anything in it to even brush on in your brows. I expected more firctge exuberant price. I bought 2 containers and even that wasn't significant since they are so small. I never opened the second as when I did the first, when I shook it it sound like just a little bit of liquid was in it. Don't waste your money.
I have tried several lash serums! Nulastin really works! I noticed my lashes in the middle of my eyes had completely fallen out! With Nulastin my lashes have grown back!
I have lash extenstions so am not posting a photo. I am 10 weeks into using the product and ready for a refill. I was on the fence about reordering but think I may be starting to see a little difference. Also, my eyes burned for about 8 weeks but it seems to not be so bad the last couple. I want to give it a fair try as I do think it is a good product and an ethical company.
This product gave me a horrible redness and burning in my eyes and eyelids, the area around my eyes are so red!
I cannot say enough good things about these products! I have been using them religiously since late January/early February 2019 and have seen amazing results. But even more than the products (which are FANTASTIC) I'm even more impressed by Leah Garcia who is the face and heart behind this brand! She is a phenomenal person and is so diligent in making sure that her customers are happy and that her products are second to none. I have experienced a couple of issues with shipping over the months that I have been using Nulastin, and each time Leah has personally checked on things and made sure I received my orders. She reached out through emails to communicate exactly what is happening and provided discount coupons for future orders. This week, she even called me on the phone to make sure I was happy and that blew me away! I have never experienced anything like that before from a company. She treated me more like a friend than a customer! I cannot recommend Nulastin and Leah Garcia highly enough. I give 100+ stars!
I have seen some people wondering why the lash and brow tubes are so small. The company explains that they do not package in larger/flashier packaging opting instead to use truthfully sized tubes.
They are the perfect size for tucking in a purse or carry on. My first order of lash and brow lasted 9 weeks! Just one more reason to love this company. I hate opening a package and finding it half full or hollow underneath. This company packages honestly, provides a great product and has made me a believer.
Hey Cheryl - Thank you for your comment on this. I really appreciate it.
I am so excited and happy to write and let you know of my wonderful results with the lash and brow combo.
I am 55 and due to stress and thyroid issues, was watching my lashes and brows disappear at a startling pace. I tried fillers, volumizing mascaras and brow thickeners. They were terrible as I am not a makeup person. On me, it was so obvious...
Long story short - I ordered the lash and brow pack on May 15,2019. Today is June 29,2019. I started out using it once a day and am now using both morning and night. I am ordering again and also would like to try the skin care products.
Thank you! I can not adequately convey to you how grateful I am to see the growth and fullness back in my lashes and brows. I had to (carefully) wipe away tears this morning when I realized that it was becoming more difficult to get the wand behind my long lashes! I took a before pic and another today. Before pic was June 7, first day of use. After pic June 29,2019 I am wearing ONLY mascara in BOTH pics. That is how far gone my lashes were. Look at them now! Thank you again,
Cheryl Hasbrouck
P.s. I just placed my second order, this time including the skin care products.
I suppose they were always there, and I told myself they had simply become very blonde. But I was always trying to find the right product to add color or fullness until I tried Nulastin. They are definitely fuller and darker and I don't have to do anything with them. My son (home from college) couldn't believe it. And by the way, I'm 61 years ago of. I'm keeping a stock of this on hand forever.
We are so very, very thrilled to read this. Thank you for sharing Sinclair! Here's to continued progress.
You must get this product. Even if you have tried every product out there! Believe me, I understand. Been there done that.
I am so glad I took a step of faith and ordered Nulastin Lash serum. It really does work. Stay consistent in using it! It took a couple of months for my lashes to really be noticeably only longer, but when it happens, WOW! Last time my lashes looked this good, I was in my twenties. Now at 50, I appreciate the quality product that helps me look better. Even without makeup!
I started using the brow and lash serum a couple of months ago. I wish I had taken a before picture. My brows had been very thin and I was contemplating microblading. Since beginning Nulastin, and it did take about 5 weeks, my eyebrows are once again thick. My daughter just told me this morning that she can't believe the change! My eyelashes were always long but since menopause had become thin. Lashes look great now. I curl and go and do not need mascara. I had tried another product but my eyes burned from it and I had to stop. Though I was hesitant to try another product, I really liked Nulastin founder, LEAH Garcia's transparency and money guarantee without a time limit. SO happy I went with my gut instinct because Nulastin worked and was not irritating to my eyes. I don't follow the recommended usage but instead only use it once a day, every other day and quite sparingly. I was afraid! Even with this scaled back application, this product has given me the most beautiful results. I thank you for your wonderful products! They really do work and are non-irritating. Thank you LEAH! I don't know her but honestly feel like she cares!
Starts working within weeks and no irritation. Product has lasted for 4 months. The order was delivered in a timely manner
Thank you Shelley!
Ok so I bought this product in mid-May and was very skeptical. I have tried so many others and have not been happy with any of them. I wanted not to like this because of the price but I was very pleasantly surprised because it's the best I've used and totally works. My first tube literally just ran out two days ago so it definitely lasted a month and a half despite the size and with twice a day use! I had very sparse Brows growing up in the 80s and plucking like crazy so I got micro blading which looked terrible with sparse blonde brow is showing through. Nulastin has Totally filled in most is the spots! Buying 2nd one now!
Thank you for taking the leap Mia! Really appreciate your business and your fabulous review.
Know what you are buying. There is barely any product in these tubes. They are smaller than sample sizes. I paid $139.95 for two of the smallest tubes!
Actually the tubes are not sample sizes. They are 3mL of serum, comparable with industry standard. Most women get 2-3 months from one tube. Sorry you were disappointed at first glance. We would love to know how the results go once you finish. Please feel free to reach out to us at the company. Our goal is your complete satisfaction.
My lashes and brows have thinned as I've aged, but this Lash & Brow Dual System with Keracyte® Elastin Complex has filled my brows nearly completely in, and although my lashes have not filled in as well yet, they are *LOOOOOONG*! I'll definitely be replenishing my supply.
Awesome! Thanks so much Leslie. Here's to continued development. :)
My eyelashes were short and stubby. I don't like wearing false eyelashes, and I did not have much luck with mascaras that made big promises. Nulastin delivers! After about a month, I saw a noticeable difference. They are now long and thick. Love! As a result, I bought the brow serum and skincare. This skeptic is a believer.
I cannot recommend Nulastin enough and actually have recommended it to many of my friends! I lost all of my hair, eyebrows, and eyelashes in 2016 due to chemotherapy. I was also recently diagnosed with Hashimoto's (low thyroid) which definitely did not help the hair loss or regrowth. Although my hair came back (mostly, but still thin on top), my eyebrows did not and my lashes were short and thin. I tried Latisse for 6 months with very little regrowth on my brows. I had been "drawing on" my brows for over 2 years and was ready to try tattooing or micro blading but decided to try one more product after chatting with Leah on Facebook. I just have to say that the personalized response and customer service is phenomenal with this company! I started using Nulastin on January 1st 2019 and the pictures say it all! I would never leave home without drawing my brows on before, now I don't have to do anything to them! I'm getting ready to order the lash serum and skin care line next... I'll keep you posted!

This truly brings tears of happiness to my eyes. Thank you for sharing your testimonial. You deserve all the blessings your heart desires. [Leah Garcia, Founder & CEO]
Not only did I see thickness quickly, but their customer service is fantastic. Better than latisse and faster results. I am a lifelong customer! Kudos to Leah Garcia for making this fantastic product.
I appreciate this note so much Maureen. Thank you!
I'm 71 years old and my brows had thinned over the years. After 2 months of using Nulastin I am blown away by the results. My brows are now totally filled in and look better than they have in decades. I'm still using the first tube of the lash serum and my lashes are longer and thicker than they have ever been. I'm thrilled to have found a product that actually works as advertised!
I am 75 years old and have tried Latisse (you can only get it from a dermatologist and it is way more than Nulastin!) and other eyelash growth products but I decided to give Nulastin a chance and even though it took about four weeks to start seeing results I am still on my first bottle and my eyelashes are amazing! My eyebrows have always been fine but not my eyelashes and now others ask me "what have you done to get your eyelashes to grow like that!" I will continue to use Nulastin and will also give it as gifts to family and dear friends.
I was born with gorgeous long and dark lashes (even had a 5th grade teacher tell me to go to the girls room and wash off the mascara on my eyes... and of course I was not wearing any). But 40 years of trying to look "finished" with my makeup and using mascara had ruined them... becoming short and sparse. I tried Nulastin because I had been looking for a natural solution, so I researched and loved what I read about the ingredients and the company philosophy. I started in early August 2018 and used it two times a day (and I am still using my first tube). My lashes are long, dark, and healthy again... and oh by the way I am 60 and I never ever thought they would look like the lashes of my youth ever again. My lashes look amazing and I could not be happier with my results and have had people comment on them out of the blue. I no longer wear any mascara... and I do not need to!
Answer: The serum should not stop working and there is no evidence clinically that would suggest individuals become immune to the formula. However, because our biology is unique and our systems are constantly going through phases of growth and repair, stress and life, we have noticed that there are seasons when visible changes like less robust growth occurs. Our Founder and CEO, Leah Garcia has been a go-to for understanding the ebb and flow of results. For example, she too experienced a time-period after using the serum for over two years when her lashes were just not responding as magnificently. She stopped using the formula for 30 or so days and then, re-introduced it. Her lashes not only kicked into another natural growth-spurt, they came in luxuriously feathery and symmetrical. We don't have a definitive timeline on how long to rest, and there is nothing scientific about this troubleshooting tip. It's just a bit of real world creativity.
Answer: Hi Beth, great question. Our BROW serum is fragrance free, so no need to worry! If you have any additional questions feel free to email us at [email protected].
Answer: You should continue using the product as an ongoing part of your daily routine. If you discontinue use, your skin, lashes, brows, and hair will gradually revert back to their original appearance. The good news is that you can decrease usage after you've achieved a desired look. For LASH, BROW, and HAIR products: Once you reach a point of satisfaction, you can apply the serum once per day. Another option is to decrease application to three or four times per week. When you want to increase the results again, go back to using twice per day.

GMP programs offers assurance the filling process for our 3mL serum adheres to strict standards. If you could please email us at [email protected], we would be happy to further assist you.
Answer: Thank you for reaching out and sharing your concern. First off, we would like to thank you for being a loyal customer.

We recommend keeping the unused serum in the refrigerator until you are ready to use it again, so the DNA proteins maintain their full potential. Please keep us posted on your progress.
Answer: We have heard from many customers with hypothyroidism. Many of them have seen great success while using NULASTIN. There is an intimate connection between the hair follicles and the extracellular matrix that supports the follicles in the skin. Not only is elastin and its precursor, Elastatropin® (our exclusive DNA protein), synthesized by the cells in the hair follicles, but the follicles themselves appear to depend on elastin and the structure of its matrix for their function and vitality. NULASTIN nurtures the cells that produce hair follicles. Our formula has five active ingredients - all designed to deliver positive results. That said, everyone is different. What we can not predict is how you will respond to NULASTIN's follicle fortifying serum.
Answer: We have products for the LASH, BROW, SKIN and HAIR. You can find all of our products on our website!
Answer: Regarding the prevention of male pattern baldness, we are confident that addressing the health of the hair follicles in the scalp, specifically the elastin and Keratin proteins will improve the vitality of the hair. But in all honestly, if male pattern baldness has already damaged the follicles beyond repair, there is no treatment that can bring dead hair back to life. That being said, if there is life in the follicle - no matter how dormant it may be, we believe that we can help! Certain spots can be problematic and may take six months or longer to look better.
Answer: Your brows, lashes, and hair will stay thick through their natural growth cycle, then they will return to their regular state when you stop using the serum. The good news, is that you can back off after you achieve a desired look. Once you reach a point of satisfaction, you can apply the serum 1x per day. Another option is to decrease application to three or four times per week. When you want to pump up the results again, go back to 2x per day use.

Hi Louise - Quick question? Did you reach out to NULASTIN Customer Care when you first experience frustration? Our VIP Specialists are exceptional at customer satisfaction. Without knowing your last name, it's hard to find you in the order system. We do have a number of Lousie's... but no one with a K in their last name. We would love to make this right for you. Our goal is for you to be happy and get the results you are seeking. May I throw out an olive branch and have you contact us at [email protected]? (customercare at nulastin dot com).
Quick comment on formula viscosity. It's much thicker than water. If it were water, it would drip when applied to the lashes and brows and you defiantly don't want that. As for the container size. Not sure what to say there. We provide 3mL of serum in a container that has enough space to accommodate the displacement once the wand/applicator is plunged inside. The internal and external volume of these tubes is substantial. Not sure if you've ever purchased a liquid eyeliner? If so, it may be worth revisiting the visual compared to a beefed, up, double walled lip gloss.
Looking forward to hearing from you.
At Your Service,
Leah Garcia
