My son is using this at the moment and he's not really a fan. He's entered into those wonderful 'teenage years' where your skin becomes super fussy.
He likes the fact that it has a roller ball applicator as it makes it quick and easy to use.
He does have sensitive skin (just like his Mum, poor kid) so fragrance has to be minimal which this product is so thats a positive.
Does it zap spots like it promises? He doesn't think it does so will be on the hunt for another product for him.
I don't think it gives results in just 4 hours. I can only see the difference after it's applied more often on my troublesome spot. More of a slow burning kind of treatment than an instant zapper.
It doesn't work on cystic acnes but works wonderfully on those smaller hormonal ones that turn up before period. It's amazing when used on pimples that have been popped, seemed to speed healing time.
