FAQs

Yes, when used consistently, a quality eyebrow serum, such as the UKLASH Eyebrow Serum, can help improve the appearance of brow health, fullness and strength. UKLASH Eyebrow Serum conditions the hairs with a lightweight formula that supports healthier-looking brows in as little as four to six weeks. It is a simple step that helps your brows look bolder and fuller over time. To learn more about what brow serum does for your eyebrows, head to our article here.

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

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 Eyebrow Serum may be a good alternative. It's 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.

Yes, when they are well formulated and thoroughly tested, eyebrow 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 brow 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.

Yes, a good quality eyebrow serum, such as the UKBROW Eyebrow Serum, can help with overplucked brows, but it depends on the hair follicle.

If the follicle is still active, consistent use of an eyebrow serum can help support the natural growth cycle, encouraging brows to look fuller and healthier over time. However, if an area has been overplucked repeatedly for many years and the follicle is no longer active, regrowth may be limited. In these cases, a serum can still help improve the condition and appearance of existing brow hairs, even if complete regrowth isn’t possible.

Reviews Summary
Customers say this eyebrow serum helps their brows become thicker, fuller, and more visible. Many notice new hair growth in sparse areas and patches that hadn't grown in years. Users report seeing results within 3-6 weeks of daily use, with some describing dramatic transformations from barely visible brows to well-defined ones. The serum is praised for being easy to apply with a simple daily stroke. Several customers mention it helped restore brows after over-plucking, menopause, or medical treatments. Consistency appears important for maintaining results. A few users experienced no noticeable change, and one mentioned slight skin tinting.

    Incredible product for those with Triccotillomania

    This is a godsend. I suffer with triccotillomania (of the eyebrows) and needed a product that could fill in my permanent gaps which were caused from constant pulling over a span of 10 years. In just 5 weeks this product did just that, I now feel less insecure about my powdery eyebrows. Although on the pricey side, I highly recommend this product, you will notice a difference in just 5-7 days of applying (twice a day). Definitely a staple to my beauty bag!

    Brow Serum Review

    I bought the brow serum in March 2025 to try help grow my eyebrows as I had over plucked them and they were extremely thin at the ends. I was very skeptical at first as I didn’t believe something like this would work. I was pleasantly surprised even after 4 weeks, I could see the growth coming back. I used it every single night and this is my results after 14 weeks. I am honestly so so happy and still in shock how good this has worked. I would definitely recommend this to anyone wanting to try!!
