BB’s Boost Serum has finally dropped. With incredible ingredients, low-maintenance application and visible results in as little as 2 weeks, now it’s possible to grow brows and lashes that are stronger, thicker, fuller and longer than ever before. Whether your lashes are short and sparse, or you’re looking to enhance what you already have, treat brows and lashes with an intensely nourishing formula that is lightweight and gentle on the hair and skin.

Our serum enriches hair follicles with a deluxe list of natural ingredients that prolong the hair’s anagen phase, aka the active growth stage. This allows brows and lashes to grow to lengths you never knew were possible. The BB Boost Serum has been scientifically proven to strengthen and grow brows and lashes. We have dedicated time and research into hair growth, allowing us to select the best ingredients to support the growth cycle and create a world-class product that really works.


Fuji mulberry root extract is the main ingredient, renowned in hair growth tonics around the world. The extract works by prolonging the anagen phase of the growth cycle, encouraging lash and brow strands to grow longer.

Other key ingredients include flavonoids, which shorten the period of transition between the resting and growth phases, meaning the hair stays in the active phase for longer.

Biopeptides are also active in the serum, working to produce new cells to increase the hair follicle’s size, causing thicker, fuller strands to grow. By circulating blood to the hair follicles, biopeptides provide the nutrients and oxygen the hair needs to grow long and healthy.


The BB Boost Serum has been trialled on men and women. The results showed that 3 out of 5 of participants saw an improvement in their brows and lashes. In a second clinical study, the serum was tested on a trial group of people, 96% of whom found the product to be effective after just 4 weeks. Additionally, 89% found it grew their brows and lashes in length after 8 weeks. Others commented on reduced hair fall, new lash growth and longer length.

How do I use it?

Use twice daily: once in the morning and once in the evening on clean, dry skin (remove all makeup before use). Coat the brow and lash roots with a single stroke of growth serum and watch how the hairs are transformed.

How long will it take to see results?

Our clinical study found that visible results can be seen in as little as 2 weeks!

How does the serum grow brows and lashes?

The formula works by prolonging the anagen growth phase of the hair growth cycle and shortening the transition period from the resting to growth phases.

Does it really work?

Yes! 100% of participants in our study found an improvement in their lashes after 4 weeks, but consistency and patience are key. It can take up to 3 months to see results.

Can it be used with brow lam, lash lift or extensions?

We recommend discontinuing the use of the growth serum for 24 hours after a lash lift or brow lamination; 24 hours will not affect the progress of growth.

We do not recommend using it with lash extensions as the serum could affect the lash's retention.

If it doesn't work will I get my money back?

We offer a 100% money-back guarantee if you do not see any results after 3 months of continuous use.

Does it contain harmful ingredients?

The BB Lash & Brow Boost will not damage the eye in any way and it will not dissolve eye fat. Growth serums containing prostaglandin analogues have been linked to lost eye fat - creating a sunken, hollow effect - but our product does not contain this ingredient - or any hormones - and is 100% safe to use.
