I used lashboost for a total of 4 weeks. After about 1 1/2 weeks, I woke up to a stye on my eyelid.
I stopped using it until the stye went away (about 3 or 4 days) then I resumed use for the remaining 3 weeks until I got another stye, and then another, and then another. I stopped use after the first one appeared, and have been off of it for over 2 weeks, and I'm still getting breakouts on and around my eyelids. About three days ago, I had a stye develop on my right upper eye lid. It has since grown and taken over my entire eyelid, swelling to at least two times it's normal size.
I even went to the doctor today to get it checked out because it was so painful, red, and inflamed.
The doctor told me to never use it again, not that I would! I'll never purchase another Rodan and Fields product again, and will encourage others to follow suit.
