Gives an initial cooling sensation, but other than that, pointless and overpriced 

I fell for the hype! This product did literally nothing, it didn't even moisturise my lips like other reviews claimed. I'm a 50 year old woman who doesn't want actual fillers and stupidly believed the ridiculous claims that this product could achieve....I couldn't afford this and should have listened to my brain, this product is useless. Sorry! Quite like the wee roller applicator but you buy that on a Boots No.7 product and apply a cheap lip oil. Don't bother wasting your money or hopes.
