Size: 3ml / 0.10fl oz

Shelf Life: 36 Months (Unopened) / 6 Months PAO (Period After Opening).

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.

1. Remove makeup with an oil-free remover or cleanser.

2. Apply one stroke of the serum only to your upper lash line (like an eyeliner). One dip is sufficient for both eyes.

Using more than instructed will not give you better results and might increase sensitivity: Don't do multiple applications or double dips. Don’t apply it on the lower lash line (the serum will be transferred to your lower lashes when you blink).

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

FAQs

UKLASH Lash Growth Serum helps your natural lashes look longer, thicker, and fuller by nourishing the lashes from root to tip. Its powerful formula strengthens and conditions each lash, reduces breakage, and supports a healthier lash growth cycle. With consistent daily use, most users see visible results in 4–6 weeks, with fuller results by 12 weeks.

Yes, you can absolutely use an eyelash serum with lash extensions. In fact, UKLASH Eyelash Serum has become a favourite among lash techs because it helps support healthier, stronger natural lashes while maintaining your extensions. When your own lashes stay conditioned and resilient, extensions can sit better and last longer. If you want to learn why lash experts love pairing serums with extensions, you can read more in our blog here.

Yes, the original UKLASH Lash Growth Serum contains a low level of a prostaglandin analogue. This well-studied ingredient is known for effectively supporting the appearance of longer, fuller lashes. We have found the perfect balance in our formula, using a carefully measured amount that helps minimise sensitivity while still delivering visible lash-enhancing results.

We understand that some people prefer a prostaglandin analogue-free option. If that is your preference, both the UKLASH Complex Peptide Eyelash Serum and the UKLASH Sensitive Eyelash Serum are designed to support the look of healthier, fuller lashes without this ingredient.

You will start to see results from our Eyelash Growth Serum in four to six weeks, but consistency is key. With UKLASH Eyelash Serum, daily use allows the formula to condition the lash line and support fuller, longer and stronger looking lashes over time. Apply once a day to clean, dry skin and let it work with your natural lash cycle. Stay consistent and your lashes will thank you.

Yes, when they are well formulated and thoroughly tested, eyelash serums are safe to use. At UKLASH, safety is at the heart of everything we do. We work closely with experienced Biologists to develop each formula with high quality, carefully selected ingredients. Every product is designed to be suitable for daily use when applied as directed, and each one undergoes strict safety assessments before making it to the shelf.

Our lash serums are also loved and approved by Dermatologists and Ophthalmologists, who recognise the care, science and rigour behind our formulations. Their support reinforces our commitment to creating products that are effective, gentle and genuinely trusted by professionals.

Reviews Summary
Customers say this lash serum delivers noticeably longer and fuller lashes with consistent use. Many report visible results within 2-3 weeks to a few months, with lashes appearing thicker and stronger. Users appreciate the easy application and non-sticky formula. Some mention it works particularly well for recovering from lash extensions or addressing naturally sparse lashes. A few note it takes patience and regular daily use to see results. Most reviewers are repeat purchasers who've used it for months or years. Occasional feedback mentions eye sensitivity or slower-than-expected results.

    Excellent

    I’ve been using UKLash now consistently for about a year and I swear by it, I’ve noticed my lashes are longer, thicker and don’t fall out as much as they used to. I’ve recommended to so many of my friends and now using the UKHair shampoo and conditioner and love it!

    Eyelash Serum

    After losing half my eyelashes on one eye I tried lots of different remedies and products to try and grow them back. I was a bit skeptical that this serum would work but as it was a reasonable price I thought it was worth a try. The serum is easy to apply and I use it every night, it does sting slightly but I have sensitive skin. After 3 weeks I noticed a massive difference and after using it for a month my lashes have 90% grown back to how they were so I would definitely recommend this product. I bought the 3ml serum and as you only need to apply a small amount it will last for months. Photos are of the before and after 3 weeks of use and wearing mascara on both pics.

    It actually works!!

    Wasn't convinced but thought I'd give it a try...

    Consistency is definitely the key, that and patience!

    If you routinely give one swipe across both eyelashes it will work.

    Yes it takes time, yes you have to do it every night, but after a couple of months I can honestly say I've never had such long lashes in my 50 years - gone are the days of trying to stick on clusters. The serum and the tubing mascara give me lashes in more than happy with. personally my favourite of the two mascaras is the tubing one - however the other does give lovely natural length too.

    I do wish I'd taken before and then could show the difference it's made.

    Have now subscribed as it's definitely part of my nighttime routine.

    Have subscribed to the serum and mascara as really don't want to run out of either!

    Like I say, be consistent and patient and you really will see a difference.

    From someone who always had light coloured short and sparse lashes, I now get a lift and tint (perfect for not going out days lol!) and mascara for when I leave the house.

    I also had one spot on my right

    Just wish I'd have boughteyebrow that was really sparse, still using the serum from the first use, I put a tiny bit there and now have even brows!!

    They still nasty but be the best lashes in the world, but if you saw them before you'd be truly amazed...

    Just wish I'd have bought and tried it a long time ago, it may not be the cheapest, but 100% better than attempting clusters and the wasted money on those!!

    Holy Grail Lash Product!!!

    This is the only lash serum that has worked for me. I get compliments on my lashes all the time now. I do get some darkening above lash line occasionally but it's worth it for these lashes.
