Here in the US there are creams called Amlactin and Aqua Glycolic. There's also one called Lac-Hydrin that has been out for years and is available in generic. It is 12% lactic acid in cream. Your pharmacy should be able to compound acid cream for you as well, so if you can't find a commercial product, perhaps try having the pharmacist mix up a 12% lactic or 6% salicylic or 30% urea type cream. They can put it in whatever creams you already use, or a base like Velvachol.
