Our Complex Peptide Eyebrow Serum is the first of its kind - offering a record-breaking six peptides in its innovative formula. It’s best suited to those looking for thicker, healthier and more nourished brows.

The growth cycle applies to eyebrow hair in the same way it does to lashes, so this will depend on at what point in your hair cycle you start to use the product. We recommend allowing up to 12 weeks before expecting to see results. To learn more, read our guide on brow cycles here. 

If you have already achieved thicker and fuller brows using our original Eyebrow Serum, switching to our innovative Complex Peptide formula can be good as it focuses heavily on nourishing and maintaining growth, resulting in healthier and fuller-looking brows for the long term.

It is packed with 99% naturally derived and 22% organic ingredients including Pea Peptides, Hyaluronic Acid, Hydrolyzed Wheat Protein, Hexapeptide-8 (Acetyl Hexapeptide-8) and Copper Tripeptide-1 amongst many more - all of which combine to moisturise, strengthen and stimulate brow growth from the root.

As leaders in the Eyebrow Growth Serum category, we want to make sure we’re catering to all customers in helping achieve longer and fuller-looking brows. Our original Eyebrow Serum was our first innovation and our new Complex Peptide Eyebrow Serum pushes the boundaries by being an industry-first, packed with more peptides than any other serum on the market.

    Amazing Eyebrow serum

    I never write reviews but l feel l have too .

    I am in my late 50’s and plucked my eyebrows for many years ( l am dark and they were bushy )

    But l think over the years l plucked too much .

    Had eyebrow Tattoo which faded also as they were short .

    I used the eyelash serum which had fantastic results so thought l would try the eyebrow serum .

    So glad l did as after l month new hair us growing and for the first time in years they are starting to resemble how they used to look many years ago.

    Believe me this stuff is truly amazing and about to order more .

    It does what it says on the tin and it works .

    Best eyelash serum on the market!

    My brows grow so thick and it keeps them that way. I’ve gone back to others but this is worth the price.

    Fan of the Lash serum, just started with the Brow serum!

    I've been using the Lash serum and have seen great results, so I've started using the Brow serum and I'm very curious what this does to my brows!
