My step-mother swears by this product, also. She has regrown her eyelashes and they are stronger and thicker than ever.
For those of you who suffer with stubby eye lashes like me, this is a miracle formula. I heard (but haven't personally experienced) that fake eyelashes are a pain - expensive, itchy, painful, etc. My beautician recommended this product and I noticed results within about 10 days! My eyelashes were much MUCH longer and slightly fuller. Results vary from dramatic to subtle. I would apply the product before bed every night but as time passed, I reduced the frequency to every 2 or 3 nights with same results so the bottle lasted me about 6 months!
