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 eyes

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

How often?

  • Growth phase (first 12 weeks): every day
  • Maintenance phase: 3-4 times per week (every other day)

Important

  • Avoid direct contact with the eyes
  • Do not use if you are pregnant, nursing or under 18
  • Keep out of reach of children
  • Patch testing is recommended and if redness or irritation occurs, discontinue use
  • If you have any preexisting conditions, consult your doctor before use

FAQs

UKLASH Eyelash 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 Eyelash 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 the chance of sensitivity where possible 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 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.

Reviews Summary
Customers say this lash serum makes their eyelashes longer, thicker, and fuller. Many report visible results within 2-6 weeks of nightly use, with some seeing changes as early as 2 weeks. Users frequently mention their lashes becoming healthier and stronger, particularly after damage from extensions. The serum appears easy to apply and dries quickly. Several customers note they can now skip mascara or receive compliments on their natural lashes. Some experience eye irritation or stinging, leading them to consider the sensitive formula. A few users report no results after consistent use for several months.

    Best Product EVER!!

    Well, what can I say, I will never look back! I hit my forties, my eyelashes became nonexistent and I was sick of piling on the lash primer followed by mascara then getting it all off on a night time was major task! I decided to have lash extensions, then my beautician told me about UKlash and how amazing it is…she was not wrong! Three months in and I’m saving a fortune; my lashes are healthier, I never have to wear mascara and it’s just so much cleaner, quicker and simplier! Thank you so much, UKlash!

    It really works!

    I was sceptical as no lash serums have worked for me before, but I’m really impressed with this one - quite expensive but worth the money. My picture is first day using it and then 10 days after use every night. No mascara on both pics.
