I have used individual eyelash extensions and it has left my lashes damaged, so someone recommended using a product such as this. Made sense. Some of the prices around start at aout £30 so I thought this was a bargain. Delivery was very prompt, no complaints there. The applicator is quite stiff, it isn't a brush, it's similar to cheaper liquid eyeliner applicators which I have always found slightly difficult to use. I applied the product as suggested, it was like applying menthol to the eyes. It began to burn and blinking made it worse. Even trying to stare straight ahead without blinking was impossible. I had to wash it off quickly. This product is not ronseal. It doesn't do what it says on the tin. I wouldn't advise others to avoid it, maybe I just have sensitive eyes or something. But I would say be wary and keep the packaging pristine, you may have to return it.
