Hi, thanks for your query.
which appears mostly in winter and related to dry skin
seems to be atopic eczema
.A dry climate and the low humidity of winter can cause the condition to flare up.
The outer layer of our skin normally acts as a barrier, protecting inner layers from irritants and infection. People with atopic dermatitis
have very dry skin that isn't as protective.
Use mild cleansers like syndets for washing face as they maintain slightly acidic Ph of skin and apply a moisturizing cream or ointment after washing, throughout the year.
Hope this solves your query.
