“I lost eyelashes on chemotherapy and was recommended the lash serum by a friend who had also had chemo. My eyelashes have genuinely grown back even longer than they were before they fell out and everyone has been complimenting me on them. They are noticeably long and thick looking. Really highly recommend to anyone who has lost lashes.”

I had chemotherapy last year and have been using the OptiLaboratories Lash Growth Treatment ever since. I can honestly say it’s one of the most incredible products I’ve ever used.
I’ll admit, my expectations were low—we’ve all tried products that promise everything and deliver very little. But this completely exceeded anything I imagined.
My lashes had been significantly affected by chemo and ongoing medication, but since using this treatment, they’ve grown stronger and healthier over time. I now have noticeably longer, fuller lashes, and it’s made such a difference to how I feel.
For the first time in a long time, I feel genuinely confident again”
