What It Does

Our Let It Grow Lash Duo pairs the UK's #1 Lash Serum** with our bestselling Black Tubing Mascara for a fuss-free routine that achieves all day definition without compromising lash health.

Why It's Special

This is the perfect lash duo for anyone wanting fuller-looking, defined lashes without the high-maintenance routine. Our Original Lash Serum helps support healthier-looking lashes over time, while our Black Tubing Mascara wraps each lash in lightweight tubing technology for lifted, smudge-resistant definition that removes easily with warm water. The result is lashes that look good now and feel cared for long after removal.

Benefits

- Long Term Lash Care - Join the 84% who saw longer-looking lashes and 80% who saw fuller-looking lashes in as little as four weeks* with the UK’s #1 Lash Serum**, paired with a nourishing tubing mascara that removes gently with no tugging.

- Everyday Wear - Apply lash serum once a day for real results in as little as four weeks, then swipe on the perfect everyday mascara for lightweight, comfortable definition that never feels heavy on lashes.

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, when used consistently, a quality eyelash serum, such as the UKLASH Eyelash Serum, can help improve the appearance of lash length, fullness and strength. UKLASH Eyelash Serum conditions the lash line with a lightweight formula that supports healthier-looking lashes in as little as four to six weeks. It is a simple step that helps your lashes look bolder and fuller over time.

Yes, although we always recommend patch testing first, as with any new skincare product, sensitivity may occur. Apply a small amount behind the ear or on the inner arm and wait 24 hours before full application. If you do experience irritation, our UKLASH Complex Peptide Eyelash Serum and UKLASH Sensitive Eyelash Serum may be good alternatives. They are both formulated without a prostaglandin analogue, which can sometimes cause sensitivity for some people. These gentler options still support the look of healthier, fuller lashes while keeping your routine comfortable. If you're still unsure about which UKLASH Lash Serum might work for you, take our Lash Serum quiz here to find out.

Tubing mascara is a type of mascara that wraps each lash in tiny, flexible polymer 'tubes', rather than coating them with traditional pigment. These tubes lengthen and define lashes without smudging or flaking, and they remove easily with warm water and gentle pressure, making them perfect to pair with a lash serum and continue your natural lash journey without unnecessary damage. To learn more about what tubing mascara is, head to our article here.

To remove tubing mascara, use warm water only. Gently soak your lashes, then apply light pressure with clean fingers or a cotton pad and slide the tubes off to break down the formula. There’s no need for makeup remover or rubbing, making it a simple, lash-friendly way to cleanse at the end of the day without unnecessary damage.

Reviews Summary
Customers say this mascara delivers lengthening and volume with no smudging or clumping, staying put all day. The tubing formula removes easily with warm water. Many appreciate the brown shade option and note it makes lashes look fuller and more defined. The accompanying lash serum shows visible results within 4-6 weeks of consistent use, with customers reporting noticeably longer and thicker lashes. Users find both products easy to apply and comfortable. Some mention minor concerns: occasional flaking, the brush being large, or the serum requiring patience and daily application for best results.

    I’ve recently started using the serum so it’s a bit early to say if it’s working. I’ve given it 4 stars as I’ve read the reviews and I’m hoping it works for me.
