I have been using Careprost (same stuff as Lumigan) lash enhancer for 4 weeks now. I can definitely tell my lashes are longer. Not a lot longer, but my lashes reaches further up on the lash curler than they did before (easy way of measuring). The full effect doesn't come until you've used this for at least 8 weeks, so I'm waiting on the big results!
There's a difference, right? I think you can tell more on the first picture with my eyes open.
Besides seeing a difference in length, my lashes seems fuller - as if I have grown more lashes.
Four weeks ago it really didn't matter if I used YSL Faux Cils mascara or any of the other wonder mascaras that lengthens your lashes. They were just too short! Now I can really build some length! Yey!
So far I'm not experiencing any discoloration on the eyelid and no red, irritated eyes.
I will keep you posted in another 3-4 weeks :) I hope you will be able to see huge difference by then!
