I have had some issues with losing eyelashes in the last few months so I decided instead of wearing fake eyelashes I'd try something like this. I absolutely love this serum. It glides on smooth. I have really sensitive eyes and it didn't bother my eyes in the least bit. I'm really excited to see how this works after a month or even longer. It doesn't smell, so nothing to worry about with a strong smell. It's not sticky and didn't make my eyes feel heavy or anything. I highly recommend this.
