Hiya Sasha.. I looked into this treatment back in March this year. After researching on the net, I discoverred that apparently this treatment is like a 'milder' form of the original Amalan peel by Dr Krulig.
I contacted Dr Krulig who is based in teneriffe via his website, did consultation via emails pics and phonecalls. His treatment was really good and I was pleased with the results.
He told me this treatment was mainly to treat melasma but because I had lots and lots of dark acne scaring and dark patches on my face he recommended i try it.
It was quite pricey cost me 400 euros..
I'd say if yoiu want to try the cosmelan.. email Dr Krulig first to see what he says.
Anything else u wanna know, just ask.. this forum is fantastic... everyone will be pleased to help.
