3ml / 0.10fl oz
Weeks 1–4: Nourishment Begins
The lashes begin to feel nourished and conditioned as the serum strengthens the lash roots, stimulating growth and making them less prone to breakage.
Weeks 4–6: Visible Changes
The lashes start to look longer, healthier and fuller whilst the serum continues to nourish and condition the lashes at the root.
Weeks 6–8: Noticeable Growth
The lashes appear longer and stronger, showing a clear improvement in both volume and length, while the serum continues to nourish and support the lashes entering the growth phase.
Weeks 8–12: Full Results
Full results are achieved with lashes that are healthier, thicker, longer looking, and nourished, as the serum worked to stimulate growth. To maintain these results, use 3–4 times per week.

Eyebrow Serums deliver active ingredients to the roots and lengths of brow hairs to create the perfect environment for growth and to nourish and condition the hairs that are already there, prolonging the amount of time they stay attached, and in turn creating the appearance of thicker and fuller brows. Head to our article ‘How Do Eyebrow Serums Work’ to learn more.
1. Remove your makeup with an oil-free makeup remover or cleanser, such as our Lash & Brow Wash
2. Apply one stroke of the serum to your entire brow. One dip is sufficient for both brows
3. For best results, apply in the PM and allow the serum to work overnight. If applying in the AM - make sure the serum has fully dried before following with your makeup routine
Apply a small amount of the serum to a small area, such as the corner of your forehead, behind your ear, or the side of your neck. There should be no other products on the skin so that you can properly test this product. Wait around 24 hours to see if you have skin sensitivity.
In short, eyelash serums are safe to use and are typically backed by rigorous testing and stringent quality control measures. As with all beauty products, different serums can affect people differently, which is why we always encourage patch-testing prior to using the product and ask that you consult your doctor before use if you suffer from any preexisting conditions.
This will depend on what point your lashes are in their cycle when you start to use the product. Some see longer lashes in as little as 25 days, but 12 weeks is when you should expect to see full results. Read more about lash cycles.

The first photo was taken on the 5th October and the second photo just now.
I know I have make up on but the difference and the length in my lashes is unbelievable! I had very obvious bald patches in my lash line and my lower lash line most of my eyebrows had fallen out post partum. My eyebrows are slowly growing back too.
I honestly would recommend this to anyone!
Thank you UKLASH!

My eyebrows lacked a lot of definition. But after 3 months of using this eyebrow serum they are so full I'm so pleased with them. My eyelashes are so much thicker and longer too thanks to the eyelash serum.

Before buying this product I searched the reviews because honestly I thought it was just another fad product that probably wouldn’t work.
I tried out the serum in early December 24. By mid January 25 I was getting compliments on my lashes and people asking if they’re my real lashes or fake. They’ve grown so much and seem thicker and almost darker. I’ve stopped wearing mascara for the first time in about 15 years (I’m 30) and I’m absolutely blown away with these results! I’ve recommended it to everyone!! My eye lashes are so much longer that I’ve now started only using it only a few times a week! I bought the eyebrow serum too and my eye brows are growing which is a saviour considering I plucked them to non existence in my teens!! Being able to wake up and go out with no mascara on and still feel completely confident is something I never thought I’d have. Honestly this product has changed my make up routine and I couldn’t rave about it more! If you’re unsure like I was, take the leap and buy it. I honestly cannot recommend it more!
