Hello..Thanks for the query
Common causes of periorbital dermatitis
1)allergic /irritant contact dermatitis
2) atopic eczema
3) airborne contact dermatitis
You may apply steroid
preparation like Desonide
of improvement in the dermatitis.Use it 5-7 days only.
Continue the moisturizer and oral antiallergic
If you are using any eye drops/hair dyes, you need to stop them.
You should visit a dermatologist
ad undergo a patch testing to determine the allergens you are sensitive to .
Hope this is helpful,Take care!
