Brows That Look Good, Without Even Trying.

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!

I am very impressed with this product. I had purchased a bottle because my eyebrows had thinned out so much -I literally did not have hair on part of my eyebrows. After using the 1st bottle I noticed that my eyebrows had started to grow again. I am on my second bottle and have an extra in my drawer. Excellent product!

This is a good product. I haven’t used it long at all yet and can already see a small difference. I am happy with the product and the service!!

Just amazing!

I've been using both the lash serum and the brow serum for about 5months and the difference in my hair growth is astounding! This product gets fantastic results!

Happy so far!

I was skeptical at first but once I started using PrimeBrow Growth Serum, I noticed a change in my hard-to-see blonde brows. They are filling in nicely. And It’s simple to apply. It’s a bit pricey but hopefully the end result will justify the cost.

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!
