Think of them like this.
Magnetic lashes are much like a regular faux strip lash except with teeny magnets dotted along the lash line. Then, a matching faux lash that you place underneath so that it connects to the first lash. Makes sense yes?
In theory, the magnets would snap together and hey presto - perfect faux lashes.
But in my experience this NEVER happens.
What does happen, (to me anyway - and like I say, maybe other people have ace experiences), is the magnets find one another long before you want them to and OMG they're on, but also hanging off at a mad, crazy angle and wow I look very, very odd. Like capital letters ODD.
So, as per above, perhaps I am just very, very hopeless. But I have tried and tried and tried and never managed to make them work.
So what can I say - in theory they work beautifully - a full, lush lash that has magnets attached and a second lash that connects to it. But in reality? Not so much.
Of course, I also need to say I'd be delighted to hear from anyone who can make these babies work and also, teach me how.
In the meantime, I recommend you opt instead for a lash curler (for beautiful, open, sexy lashes) and one very high quality mascara in the blackest black you can find.
