Answer
We do not have a pass and ready answer to this question. It is clear that more research is needed by making some creams with different combinations of the raw materials. Then determine if a gray colouring occurs. I think the cortisones can be ruled out.
the basis of the problem is of course poly-medication, of which this regulation is a typical example. Many will react with the remark that such composition is no longer at home in modern medicine. I see a combination of metallic salts with Cortico & #039; s. And then another cocktail of Cortico & #039; s of which I do not know whether they are all ideal for dermatological practice.
your suggestion is not negligible!
