First off, the price of $100.00 that this site forced me to put down is wrong. I only paid $91.50 at Costco Pharmacy. It was not discounted but this site won't let me list anything less than $100.00. How odd.
Anyway, I love this product! I have been using Latisse for 33 days and already notice a difference! My lashes are definitely longer and thicker.
I agree with most of the other people who have posted here; lose the brushes that come with the product and get yourself a high quality eyeliner brush. I only use one drop in the cap for both of my eyes and my eyebrows. With the results I am seeing, this seems to be sufficient. Up to this point I have not experienced any side effects. I would certainly recommend Latisse!
