I've used multiple products line this and this one really works . I've been using it for over a week and can already see a difference in the length of my eyelashes and eyebrows .It didn'td cause any irritation like other products . Also, my eye color hasn't changed either . I love that it doesn't contain parabens, etc . i feel confident in this product that isit made in Germany verse China . It's so easy to apply.. I keep it on my dresser and apply right before bed .
