Skin biology (the website I got the information from) produces its own range of skincare products. I have some scarring and have heard very good reports about using some of their copper peptide products.
I know they're not 'natural' and not inkeeping with part of my philosophy of removing as many artificial chemicals as possible, but they dont have any of the really bad ingredients like glycerin or SLS and its only for the short term!
They produce a 'Gentle Cleansing' bar and gel which is pH 7.8, considerably lower than all other bars/soaps, but alkaline enough to cleanse without damage. You could look at some of their products.
I will look in to finding natural and herbal preparations, its very hard to get anything like that in the UK!
