The best positive thing that I noticed was that I did not experience any lash loss ! anymore, because from time to time I saw single lash under my eye or after using eye make-up remover. I think it was because my roots got nourished.
you can apply it before putting your mascara or just by itself ( I used the second option most of the time) because of it has kind of glossy effect it will make your lashed shiny a little. it is very light and kind of refreshing ! , however when I applied it it kind of stick my lashed together ( which I don't like ) so I usually use a clean brush to separate my lashes ( no big deal, I know for some people that won't be an issue at all).
so here are my overall points:
very light materials, non-irritable, with glossy affect
you feel a slight (tiny) difference in the length
I noticed less lash fall out (specially when I am cleaning my eye make up)
If you look for huge lash growth you will be disappointed
Combine lashes together
After a few weeks of application, it is kind of stop affecting your lashes
If you apply too much of it , it will leave white dry clumps on you lashes which I cleaned every time after application If I wanted to go out.
Price :15.99 CAN$ at Pharmaprix ( our drugstore here in Quebec); I got it for 9.99 CAN$
I will recommend trying it if you are looking for something simple and easy to condition your lashes ( but don't expect miracles, specially recommend to buy it on sale). I will finish the package that I have now , but probably won't buy anymore.
