And the lashes get color, but they are probably too thin for it to be noticeable. I used their Sensitive series before (discontinued?) and nothing happened with the eyelashes other than that I always managed to get it in my eyes.
I have the liquid now and think that the application is very smooth and I manage to avoid getting it in my eyes, and if I do get it in my eyes, I find that it doesn't burn, but I can just leave it.
A little frustrating that it was a bit complex to get hold of the instructions that couldn't be on the lid or paper in the lid.
