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 makes their lashes noticeably longer, thicker, and fuller. Many report receiving compliments on their lashes, with some friends asking if they're wearing mascara or extensions. Users typically see results after 3-8 weeks of consistent daily application, though patience is required. The serum helps restore damaged lashes from extensions and works well for older users experiencing age-related thinning. Most find it gentle and non-irritating, though a few experience eye stinging. Some note lashes return to normal when stopping use. A small number report no improvement or lash breakage after extended use.

    It works!

    One photo is after the other before. I’ve been using this serum for over 4 years now I think. It works straight away and lasts a few months per tube so it’s worth it especially if they do a sale or a discount.

    AMAZING

    Cannot believe the difference from Feb to May, my lashes have got SO much fuller and longer. I used it every night when doing my skincare before bed. I would recommend this to anyone wanting to grow their lashes. I was getting lash extensions constantly before and now I get a lash lift/tiny and can actually see them.

    It does work!

    I was dubious, but I wanted to stop getting lash extensions as they just look so unnatural and in the summer I get hay-fever and well, itching eyes and extensions dont work! I have been using the serum since February and I am pleased, my lashes definitely look thicker and darker! I will continue to use this serum as I think its worth it over extensions!
