I was highly skeptical of this serum when I first saw it but I thought I’d give it a try anyway. I have to say, I’ve noticed quite a difference with my lashes since I started using this serum. I had a medical condition in my eyes years ago that resulted in my lashes falling off and becoming very brittle. Thankfully that condition is gone thanks to treatment but my lashes suffered greatly because of it. This serum has helped my lashes become stronger (I rarely lose a lash now), they’re getting a little longer too, and I’m not sure if it’s the serum but I feel like it’s bringing some of the natural curl I had back to my lashes. I bought two and use one on my eyebrows and the other on my lashes. I would highly recommend this to anyone and everyone!
