you seem to have developed excessive dryness of skin over the stomach region. Well in case you dont have any associated itching or redness
over the same area, then you need not worry...But if there is any redness or itching ,then it can be a sign of a fungal infection
or any eczematous condition. In that case you will have to consult a skin specialist for proper assessment and diagnosis....But if there is no associated complaint, then you need not worry. Just keep your skin adequately moisturised.. apply plenty of moisturising lotions and preferably use some oil also once a day ( something like olve oil or almond oil )...
hope it helps
