I work for a physician and the Latisse rep gave those of us who wanted it a free bottle. I already have pretty long lashes...but went for it anyway! I used it as directed and saw results after about 2 weeks!! I actually had to go to using it every other day because my lashes got so long, I am now using it 1-2 times a week. My lashes are definitely longer, darker & fuller. I have not experienced any eye redness, itching or hyperpigmentation of my eyelids. I LOVE LOVE LOVE this prouct. I just wish the appicator brush was made of a more absorbant material....the brush is made of a plasticy type material & sometimes the product runs off.
