Brows That Look Good, Without Even Trying.

Your Beauty is Our Duty.

You Asked, We Answered

With PrimeBrow Serum, you may be able to see results in as little as 2 weeks and up to 70% more length and volume by week 4. Every human is different though, so be patient with yourself. Make sure to take progress pictures at Day 1, Day 30 and Day 60 to qualify for our Growth Guarantee!The important thing to remember is that all good things must take time! Growing your brows will not happen overnight and you will need to be consistent with your application. Be patient. Fuller brows are on the horizon!

Our lash-stimulating peptide complex supports the brow's natural renewal cycle making your brows thicker, bolder, and healthier. The mineral-dense formula helps replenish lashes with essential proteins and vitamins that provide luster and shine. Unique moisturizing agents provide superior hydration to brows by locking in moisture while improving flexibility and elasticity.

You should use PrimeBrow Serum 4 days per week! We recommend applying 1 time a day for the first 2 months for maximum results! Make sure that skin is clean before applying. If you forget one day, just hop right back in the next day :)

Our formula is specifically designed to be gentle and safe for everyone, including cancer-patients! Our products are also cruelty-free and vegan. However, you should still avoid getting the formula in your eyes. If eye contact occurs, rinse your eyes thoroughly with water.Also, if you are being treated with any ocular disorder, use PrimeBrow serum under the supervision of your physician. Keep out of the reach of children. We recommend that you wash your hands and face with mild soap and water prior to application.

A tube of our PrimeBrow serum will last 1-2 months, depending on how often you apply the serum. Pro Tip: Please make sure to swap out old bottles every 2 months for maximum results. Our serums don't use any yucky preservatives, so our products definitely have a shelf-life!

Growth serum review

I was pleasantly surprised. The serum really works! It is odorless and light-weight and I saw results in a few days. Thank you Prime cosmetics for being reliable and honest. This stuff works!

How Primecausemetics talked me into the brow serum

I didn’t think I needed the brow serum, since my brows are still nicely-shaped, same thickness as ever and pretty dark. But I’m very fond of the other products, I went ahead and ordered it. I’m very glad I did because, although the results weren’t as dramatic as with the mascara, I’m loving what’s happened as my brows have darkened throughout their length. So I’ll be ordering more soon!
