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.

Kind to your hair

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.

    I had no lashes and now look!

    Six years ago when I was 7 years old, I started picking out my eyelashes and they wouldn’t grow back even when I stopped picking. My mum bought me many other serums and conditioners, some were really expensive but they still wouldn’t grow. I was devastated and truly thought I would never have eyelashes ever again. I started using UKLASH on the 1st of December 2025 and I’ve used it every single day for 8 weeks. I cannot believe how much they’ve grown using this serum. My confidence and self esteem has improved so much in the last month or so. And they are still growing! The photos are from before using the serum, after 4 weeks the after 8 weeks.

    Genuinely works!

    I read all the reviews but was still sceptical. The menopause has really effected my hair and I noticed my eyelashes were getting really thin and stumpy 😩 started using this serum on January 5th 2026 and I’m blown away by how much difference it’s made, this product is genuinely fantastic - it really does work 👏🏻👏🏻👏🏻👏🏻👏🏻

    THE BEST!

    I was really sceptical about buying this product as it seemed too good to be true.. thought I would give it a go and so glad I did! I wish I had a before photo but my lashes are so much longer and a bit more fuller. The key is to be consistent I put it on every night after my night cream. It took about 4 weeks before I started to notice a difference and I’m now 6 months in. Fantastic product so easy to apply! I did try the brow version but didn’t notice much difference.. I think a better applicator on the brown gel would help.

    Amazing Product

    I was sceptical about whether this product would work. However after reading all the great reviews I thought I would give it a try. I’m absolutely thrilled with the result. My lashes were short and fine but this serum has transformed them. I don’t normally write reviews but I felt this had to be done. I’m a 63 year old lady who still likes to look after herself and I felt my lashes were a let down .. but not the case anymore. I have been using since beginning of October but did see a difference after about 8 weeks. They look even better with mascara!!

    Excellent!

    I was really sceptical about this, but it’s brilliant stuff. I’ve been using about 4/5 weeks and can see a noticeable difference in length and fullness already.
