NULASTIN Shape Altering Eyebrow Serum - Brow Serum to Shape & Define - Improves the Appearance of Sparse Eyebrows for a Fuller Look - Enriched with Hair-Strengthening Ingredients (2 Count)

This is the real deal. A product that actually delivers what it promised. I’m 58 and my brows were starting to thin a bit too much so I tried a couple other brands that weren’t as expensive but the results were mediocre. I then decided to try Nulastin despite the price point and I’m so glad I did! I noticed results in about 2-3 weeks and it has really helped thicken my brows especially the “tails.” I’m on my second tube and I use it every day. Love it!

I can't live without it now. It does work. It takes awhile but brows are a big indicator of someone's age. Nice brows and you look younger. It's pricey but worth it.

I am 78 years old, and in my youth had very heavy, dark eyebrows. At that time, I plucked my brows too much and as I aged, my brows got lighter and thinner. My initial experience with Nulastin was a purchase of both the eyebrow and eyelash serums. After about 3 months of using these serums, I noticed that my lashes and brows were not only getting longer, but they were also getting darker in color. The change to the look of my lashes and brows was actually quite dramatic, and I no longer had to use cosmetics to enhance the color or thickness of either. In fact, the dentist at one of my visits commented on how beautiful my lashes were. As mentioned in the title of this review, this stuff is expensive. So, I decided to try other serums that were much less expensive. At first I thought the less expensive serums were working, but within a few months noticed both my brows and lashes were disappearing again. OK, this may be a vanity thing, but who of us does not want to look younger and look the best we can without the use of cosmetics if at all possible. It should be noted here that these serums are not necessarily a permanent fix. Use of these serums must be continued to maintain results. To start, I used these serums twice a day. It's possible that after the desired growth has been attained, using the products could be reduced to once a day for maintenance. I have yet to try this. One thing I like about this serum vs. previous versions and other products is that tube is clear so you can see how much serum is left. For previous versions and other products I have tried, this is a guessing game. You most often can't be sure that you have used all of the serum. Yes, this stuff is expensive, but it really works. In my experience, less expensive alternatives are a waste of time and money. Since I am retired and on fixed income, these serums are an extravagance for me, but I think I am worth it. I should also mention that the new packaging shows how much serum is left in the tube. Previous to this change, you could only guess how much was left and when it was gone. For me this is a welcome change. The pictures included are from my initial use of these products. I hope this review was helpful for you.

Great product! It really works . My eyebrows were looking sparse. This product has really helped to fill them in more.. I’m on my second tube. It takes a few months to really notice.

I think this works, with limits. My brows are thicker, but there seems to be a set point. I wasn’t an over-tweezer, but I’m not going to get Lily Collins brows . I certainly notice more stray hair growth. Prefer the clear tube.

What kind of sorcery is this?!?! I haven’t had to pluck my eyebrows in nearly 15 years and now all of that has changed over the past three months that I started using this. It takes some time but IT WORKS. I consistently use it twice a day and the bald patches are filling in. I have cut down on having to use an eyebrow pencil to fill them in. Also, let it settle into your skin before you put any face cream or makeup on so it has a chance to work.

This works! Not fast, but it works. I first started over a year ago using this gel, and I had very little eyebrows left. Had to draw them on every day. Even have a joke with friends that if I am ever in the hospital or very sick, someone needs to come and draw on my eyebrows. First picture is from May 2025. I had already been using Nulastin for about 3 months and was starting to get some brows, but still needed to use eyebrow pencil to fill in. Second picture is March 2026. NO eyebrow pencil- those are my eyebrows! I even need to pluck under the arch again. Use 2 times a day - give it time - I’m thrilled with this product.

I have used this product on and off for a few years. It does work but you have to keep using it. It is expensive. I noticed after not using it for a few months my eyebrows get thinner. I find the amount of serum in the tube is skimpy and have no way of determining if the amount in there is accurate as the tube is not clear. One tube does not last 6 weeks as advertised. And I do not over use the product when applying it. So while it does work I am on the market for another brand with the key ingredients such as Isopropyl Cloprostenate (a prostaglandin analog), Myristoyl Pentapeptide-17, and Elastaplex® Technology, which support hair growth and follicle health. If i find another less-expensive option, I will update this post.
