Hi Steve,
Dermovate is a very potent corticosteroid and should only be used on small patches of affected skin and not for long periods. Certainly not for more that 4 weeks, and should be applied very thinly. Otherwise, it can cause permanent damage to the skin (as many on this site may attest to).
The most important thing is that if you use it, you have to wean yourself off it very slowly. Do not just stop. So if you are applying it twice a day, which I think is the recommended maximum dose, then you should reduce to once a day, then once every other day, then once every three days etc. Until you stop. I hope that you have got my drift
When most of us have used these topical treatments, we think "well it is only a cream, what harm can that do"? Well the answer to that question is LOTS.
Read the instructions and take care. And if you have any questions then get back to me.
Regards,
Daryl
