Ectoin

I have finally found a cream that works wonders.. Boots Dermacare Psoriasis treatment cream. It is steroid free, available without prescription and it contains an ingredient called Ectoin. I say it works wonders, my inverse psoriasis is about 90% reduced. What are other peoples experience of this and are their any other creams containing Ectoin available in the UK? I wondered if a cream with higher concentration may just shift it 100%.
