Yes, when used consistently, a quality eyelash serum, such as the UKLASH Complex Peptide Eyelash Serum, can help improve the appearance of lash length, fullness and strength. UKLASH Complex Peptide 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.
Most people start to see noticeable results with our Complex Peptide Lash Serum in around six to eight weeks of consistent daily use, with fuller-looking lashes continuing to develop up to 12 weeks. The serum works alongside your natural lash cycle, so it depends at what point in the cycle you began to apply the serum as to how quickly you'll see results. To learn more about the lash growth cycle, head to our article here.
Peptides are short chains of amino acids, which are the building blocks of proteins like Keratin, which makes up around 80-85% of your natural lashes. In lash serums, peptides help support your natural lashes by conditioning them and reinforcing the lash structure over time, working in harmony with the natural growth cycle to achieve longer, fuller and healthier-looking lashes. To read more about what peptides do for lashes, head to our article here.
Hair Growth Serums aim to stimulate hair growth at the root by supplying a range of active ingredients to the scalp and invigorating hair follicles, reducing hair loss and resulting in a thicker and fuller head of hair. To learn more about how hair growth serums work head to our article here.
We recommend allowing around 12 to 18 weeks to see results from a hair growth serum, as scalp hair grows more slowly than eyelashes and eyebrows. The hair growth cycle takes time, so consistent daily use is key, giving your scalp and hair follicles the chance to absorb the active ingredients and support the appearance of longer, stronger and healthier-looking hair over time.

I have been using the hair growth serum from UK lash every morning for 5 months following a diagnosis of alopecia areata. I'm undergoing medical treatment with a trichologist too but I think this serum has helped with my hair growth journey. I now have no shedding and my new hair seems to have grown back more healthier than ever. I use a derma roller on my scalp before applying a few drops of the serum and gently massage this on with a scalp massager brush. My first photo was taken 31.1.25 and the latest one 7.4.26, a dramatic improvement.
