FAQ

An eyelash serum is a specially formulated treatment designed to lengthen, thicken and nourish your natural eyelashes. Providing a kinder alternative to eyelash extensions, they typically contain a blend of ingredients to stimulate lash growth.

Eyelash Serums deliver active ingredients to the roots and lengths of the lashes to create the perfect environment for growth and to nourish and condition the lashes that are already there, prolonging the amount of time they stay attached and in turn creating the appearance of longer and fuller lashes. Head to our article ‘How Do Eyelash Serums Work’ to learn more.

Apply a small amount of the serum to a small area, such as the corner of your forehead, behind your ear, or the side of your neck. There should be no other products on the skin so that you can properly test this product.  Wait around 24 hours to see if you have skin sensitivity.

In short, eyelash serums are safe to use and are typically backed by rigorous testing and stringent quality control measures. As with all beauty products, different serums can affect people differently, which is why we always encourage patch-testing prior to using the product and ask that you consult your doctor before use if you suffer from any preexisting conditions.

This will depend on what point your lashes are in their cycle when you start to use the product. Some see longer lashes in as little as 25 days, but 12 weeks is when you should expect to see full results. Read more about lash cycles.

    UKLash eyelash serum

    Absolutely fantastic. I lost my eyelashes during chemo last year and they had grown back very sparse after nine months. Two months of using the serum and the number of lashes has increased amazingly and they are also longer. Highly recommended 🤩🤩🤩🤩🤩

    It really works

    I have always been fortunate to have long, full lashes but due to hormone changes in menopause my lashes had really depleted and become more sparse.

    I was rather sceptical that a product good help, but felt that I hadn't got anything to loose.

    I've been using the product every night for a couple of months and I'm really delighted with the results. My lashes are feeling far healthier, and fuller, a really great result.

    A product that actually works

    This product works. I’ve literally seen my lashes blossom because of this product. And after trying both, I actually think it’s still better than the peptide version.
