It works!

I wish I did a before and after. One week using the serum and conditioner twice a day - my lashes are impressive. I was going to wait yet noticed a difference. I applied a coat of mascara and was blown away. I cannot wait to see them in two and three weeks.

Best out there

I have never written a review for a product before but I feel like Osmo deserves it. I started using this product on January 12th and was able to see results within 1 month. After 3 months my eyelashes are thicker, longer, and darker.

Long lashes

I love this product. I have very sensitives eyes. When I first used it I had to slow down to every few days and then build up to daily as it was causing my eyelids to hurt. Once I was used to it, i started daily use for a few months then went back to every other day. I now have long lashes that just need a little mascara to look like I have a light sent of falsies on. Highly recommend.
