I'm using this serum from 1 moth and a half now and I've noticed some improvements but nothing special. The length is increased a bit but not the volume. 

I don't use mascara anymore! I use it once a day and I'm still on the first tube (I started in June)

Thia does the job just like the previous brand I used, but Sweed is more affordable. You need to keep using it for lasting results. 

More thick and definitely longer eyelashes in one month!

I’ve been trying this lash serum for over a week and I already love it. I’ve already seen some little improvements in my lashes. Highly recommended, it doesn’t have any smell, it does not irritate my eyes and it’s really easy to use, the applicator is very good.
