I've moved to NZ and the brand I'm using currently is Osmosis. Its an american brand created by a doctor and by far the best I've come across!! (trust me, I've worked with a lot of brands)
they're results based thanks to the knowledge of the doctor who started it, holistic in the sense that they no longer want to damage the skin in order to make it look good and natural, no SLS, parabens, artificial fragrances or colours!!
I'm sure you can get it in the UK but it's not very big... but it needs to be! Honestly has changed my life!
