FAQ

Our Complex Peptide Eyelash & Eyebrow Serums are the first of their kind - offering a record-breaking six peptides in its innovative formula. It’s best suited to those looking for longer, healthier and more nourished lashes and brows.

This will depend on what point your lashes and brows are in their cycle when you start to use the product. Some see longer lashes and fuller brows in as little as 25 days, but 12 weeks is when you should expect to see full results. Read more about lash cycles here.

If you have already achieved longer and fuller lashes and brows using our original serums, switching to our innovative Complex Peptide formula can be good as it focuses heavily on nourishing and maintaining length, resulting in healthier and fuller-looking lashes and 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 lash and brows growth from the root.

As leaders in the Eyelash Growth Serum category, we want to make sure we’re catering to all customers in helping achieve longer and fuller-looking lashes. Our original Eyelash Serum was our first innovation, our Sensitive Eyelash Serum caters to those who are looking for a gentler approach to growth, and our new Complex Peptide Eyelash Serum pushes the boundaries by being an industry-first, packed with more peptides than any other serum on the market.

Reviews Summary
Customers say this serum noticeably lengthens their lashes within a few weeks of consistent use. Many reviews mention improved strength and fullness, particularly among those with age-related thinning. While most see positive results after 2-3 months, some note slower progress or minimal changes. The application process is described as simple, though a few mention the formula can be runny. Some prefer the original version, while others find this formula more gentle.

    I feel like this is an upgrade from the OG UKLash serum, it doesn’t leave dark circles or dark lines on your eyelids so I’m obsessed. Works super well slightly thicker formula. 10/10

    Not working any more!

    I’ve used uk lash for years and have loved my spectacularly long lashes my pride and joy until it stopped working. I changed to the newer complex peptide to see if it would help and have been using it since it became available with a small improvement but my lashes are still struggling
