Hi! kapil ,
Welcome to HelathcareMagic forum,
If the patches are slightly lighter than the original color ,then it must be PITIRYIASIS ALBA(P.ALBA).The other possibility is a
sunburn reaction ,but only if she gets more itching when exposed to sun .
P.ALBA is a condition due to
dry skin ,excess exposure to sun light & excess use of soap.
The best treatment in such a case is use of a good ,moisturizer along with a moisturizing soap.And regular use of a good spf sunscreen daily three times.
These patches may take long time to go,& for faster recovery one may use a mild
topical steroid over the patch for just few day.
If you have consulted a
dermatologist ,kindly let me know what has been prescribed and what was his diagnosis ,so that I can help you further.
regards,
Dr.chawda
