Grüum’s dual-ended grö Eyelash and Brow Serum is winning over beauty fans who want fuller, healthier-looking lashes and brows without the premium price tag – and some shoppers say they noticed a difference in less than a month.
Maintaining full and healthy-looking brows and lashes can require a bit of extra care, and the right serum can make a world of difference. While there are numerous expensive options available, shoppers say they have discovered a wallet-friendly favourite that genuinely delivers results.
grüum’s grö Eyelash and Brow Serum is formulated to work on both lashes and brows, enabling shoppers to simplify their routine while saving money compared with purchasing separate products. Early reviews have commended the serum for making lashes look fuller and healthier, without the hefty price tag attached to many comparable treatments.
Normally retailing for £12, at the time of writing, the product has been cut to £8 on sale. Once the discount ends, beauty lovers can save on the £12 price tag with code LINK15.

The dual-ended serum is loaded with ingredients formulated to nourish and strengthen hair, including caffeine to help energise follicles and boost micro-circulation, which can assist in awakening dormant hairs. It also features hyaluronic acid to hydrate and condition lashes and brows, helping them appear healthier over time.
Unlike certain lash serums, grüum’s oil-free formula is suitable for contact lens wearers and those with eyelash extensions, making it a straightforward addition to most beauty regimens. To use, shoppers should cleanse and dry the targeted area before applying a thin layer of serum.

The product can then be brushed through lashes or brows using the integrated bristle brush to ensure every strand is covered. For optimal results, the Manchester-based brand advises applying the serum twice daily, morning and evening, for the initial 12 weeks. Shoppers should be aware that standard delivery costs £4.95, reports the Mirror.
Apart from grüum, another well-regarded eyelash serum is Uklash’s Lash Growth Serum (£38). The formula is designed to deliver 85% longer, 80% fuller-looking lashes, featuring ingredients that have been approved by dermatologists and ophthalmologists.
Alternatively, RapidBrow’s Eyebrow Enhancing Serum (£27, Lookfantastic) offers an option for achieving fuller brows. The deeply nourishing formula, which is said to produce visible results within 60 days, contains keratin, sweet almond extract and polypeptides.
As previously mentioned, the grö Eyelash and Brow Serum has received numerous positive reviews from satisfied shoppers. This customer shared: “I was sceptical about this product, but I must say it’s really helped my eyelashes look so much fuller and for a really reasonable price! No complaints from me.”
Meanwhile, another said: “I’ve been using this lash serum for six weeks, and I didn’t expect THIS much of a difference. My lashes look way longer, fuller and more lifted even without mascara.
“When I do wear mascara, they look insane! My lashes are touching my eyebrows. I’m so happy.”
However, as with all beauty products, not everyone has been equally impressed. This person encountered an issue with the applicator, stating: “Product is great, eyebrows and lashes felt in really good condition….but mascara wand for the brows and the brush for your lashes was way too hard for me.”
On a more positive note, one devoted fan of the grö Eyelash and Brow Serum commented: “I am so disappointed that I didn’t start to use this sooner. I am so pleased with my results and can’t recommend this product more.”
While another remarked: “I have been using this lash serum more or less for two months now and my lashes are definitely fuller.”
Alongside the Eyelash and Brow Serum, grüum has recently expanded its range with the addition of the Melting Cleansing Balm (£18) and Clear Complexion Gel Serum (£13). The cleansing balm harnesses the power of shea butter and coconut oil to deeply nourish the skin and stimulate collagen production, with one customer noting: “It lasts for ages and is really good value.”
The Clear Complexion Gel Serum, meanwhile, combines a powerful blend of natural actives to tackle acne-prone skin without the use of harsh chemicals or stripping agents. One satisfied customer enthused: “My skin is the clearest it’s ever been. I get many compliments on my skin, too.”
