NYK1 Brow Force Serum – What Is It?

NYK1 Brow Force Serum is a multipurpose serum which promises to nourish and strengthen hair follicles giving fuller-looking brows within 6 to 8 weeks. Brow Force is the sister to Lash Force the lash growth serum of the same ingredients, however, it contains a different applicator; one that allows you to apply the serum to the brows in an efficacious manner.


As mentioned above Brow Force Serum comes with a doe-foot applicator, whereas Lash Force comes with a small brush. Both applicators are designed to apply the serum in the easiest way possible. The doe-foot is of a decent size, holds the serum well and glides over the brows with ease. Brow Force comes in a gold tube, very much like a regular mascara.

Within the outer card tube are detailed instructions on how the serum works and how to use it, you simply can’t go wrong!

NYK1 Brow Force contains a whopping 8 mL tube of serum. I will say this is one of the most impressive things about both the brow and lash serum from this brand. The actual size of the products in comparison to other brands is excellent in terms of value for money.

Here is a selection to give you an idea of price comparisons:

Rapid Lash Eyebrow Enhancing Serum 3ml £36.35 = £12.22 per ml

RevitaBrow Eyebrow Serum 3ml £89.00 = £29.67 per ml

Elizabeth Arden Prevage Clinical Lash & Brow Enhancing Serum 4ml £92.00 = £23.00 per ml

UKbrow Eyebrow Growth Serum 3ml £37.99 = £13.33 per ml

NKY1 Brow Force Serum 8ml £69.95=£8.75 per ml – However it is currently on offer at £44.95 = £5.61 per ml

There is also my discount code that can be used on top of that.


Thanks to the applicator it is quick and easy to apply the serum to your brows both morning and night. The serum is transparent and absorbs quickly leaving no residue.

I have tested various makeup products on top of the serum and have had no issues with wear or application. Eyebrow pens can sometimes struggle to draw or adhere to the brows if there is skincare in that area (I’d recommend ensuring your brows are skincare free if you’re having this issue) – I had no problems with three different eyebrow pens and this serum. I also tested various brow pencils and gels and again, these applied well and lasted throughout the day.


NYK1 Brow Force Serum is fortified with Biotin, ginseng, and vitamin B to help nourish and stimulate the hair follicles. This leads to a strengthening of the hairs and thicker and fuller brows. Brow Force is dermatologically and Ophthalmologist tested.

My Results

Prior to being my Brow Force treatment, I dyed my brows. I did this because I have quite fair brow hairs and I wanted to be able to show all of the hairs that I do have! I was sure to do the exact same process at the end of my treatment for my ‘after’ photos. I think I dyed them a little darker the first time however!

All photos are taken in natural daylight by a window, unedited, iphone 13pro, front camera.

My main areas of concern were the arch. Particularly on my left brow. I lost a patch there and another patch on my right brow. This has happened as I’ve been experiencing a lot of hair loss in general due to my ill health.

It took a few weeks longer for me to notice changes with my brows compared to my lashes with the lash growth serum. So as suggested, stick with it!

The first thing that I noticed was how thick and full the front third of both brows became! I wish you could brush them for yourselves! They truly have gained fullness in that area! The other areas took a little longer to show results, however, there has always been less hair there. What I began to notice was that areas that were quite sparse began to show hair and less skin and the two areas that had lost hair, began to show it! I was overjoyed!

I am lucky in that any brow mishaps of the 90s & 00s thankfully haven’t left me too scarred, however, my ill health rather has left an impact of late. Where I visually notice a difference is in the patches which are no longer there in my after photos and the arch of my brows where I had lost hair now has regained fullness. Of course, as I mentioned the front part of my brows are incredilby full and plentiful to comb through!

So while I don’t have the most sparse brows to begin with I think you can see the results in the areas I was hoping for and all around my brows are fuller. They also feel more nourished and I have had to keep on top of trimming as they grow so fast!

I will definitely be topping up my Brow Force, just as I do my Lash Force; I am a convert!
