Application is simple: the serum should be applied once nightly along the base of the upper lashes using its precision brush, ensuring the eye area is clean and free from any makeup or skincare products before use.

For those seeking a more affordable option, The Ordinary Multi-Peptide Lash and Brow Serum, priced at £11.36 at Cult Beauty, offers a lightweight formula that works on both lashes and brows using four peptide technologies to boost hair thickness.
Another alternative is UKLash’s Lash Growth Serum, which costs £32.50. This award-winning product enhances natural keratin production, promising longer, fuller lashes in as little as 25 days.
Customer Experiences and Reviews of RapidLash
RapidLash has received positive feedback from users who praise its efficiency and value. One satisfied customer stated,
I had longer lashes within two weeks. I really like how quickly you get results from it, making your lashes a little thicker and a lot longer.
Another user added,
This really does work! Been using it for a couple of years, and my lashes are so strong and long. It’s a great value buy in comparison to other brands.
Some users also highlighted the gentleness of the serum, with one noting,
This makes my eyelashes feel nice and moisturised and is gentle around my sensitive eye area. I do wish it were on a brush a bit more like a mascara brush, as it takes too long to apply with the tiny pointy brush provided.
Meanwhile, another enthusiast shared rapid success, saying,
I have great results with this product, it says around a month or two for real results, but I literally get results from this serum in a week or so, it’s brilliant stuff.
