Review (3/5): Good for brittle lashes
I have used this a few times now so I don't expect to see any changes yet. It's clear oil so it doesn't have any coloring. After application very small oil droplets form on the lashes that can smear. I just wait for them to dry. I believe the best way of using this is in the night before going to bed using on clean lashes. I have not used them under mascara but from what I have seen so far I would expect it to smear the mascara along with the oil all over my eyes. I don't believe this is a miracle product as far as "enhancing" the lashes but I do believe that the oil helps nourishing brittle lashes.
