I use it and it works really well. My derm frequently runs a special of buy 2, get one free so it works out to about $70 a bottle. I used it every day for 3 to 4 months and now I use it about every other day. My lashes are blonde so I also have them tinted. It's a big investment but I'm old and it makes me feel good and I love that I don't have to wear mascara.
