Hi,
It seems that you may be having either irritant or
allergic dermatitis.
There may be some irritant or allergen which might be responsible.
It may be dust,house dust,house dustmite,pollens insects,perfume,cosmetics, wool,grass,soap..and so on.
In your case,sun exposure is is aggravating factor...So, be protected from sun exposure.
You
consult dermatologist for perfect diagnosis and treatment...
Anti histaminics and
steroids in tappering dose might be helpful in alleviating your disease.
Local application of steroid cream may improve the disease.
Avoid soap bath.
Keep away yourself from suspected culprit.
You might be improved.
I hope you got my answer.
Thanks.
