Tomorrow, I will have been using Future Length for 13 weeks, and I'm very pleased.I'd been using the much more expensive Revitalash right up until I began the Future Length, and my lashes look really good, and I've experienced absolutely no irritation or discoloration.I'm down to one coat of mascara (MAC Optimum Black), over a light coat of primer, for added volume, and while nobody's asked if I'm wearing false lashes, my lashes haven't looked this good since I was in my teens (I'm now 47).I've officially kicked Revitalash to the curb, which was my goal, so I'm happy, and my budget is happy, too!I'm glad Future Length is permanent, because I plan to keep buying it.
