As far as acne is concerned, taking oral azithromycin
would help. If the lesions are less in number, it can also be managed with topical medicines like adapalene
gel. Use a salicylic acid
based face wash and a water based moisturiser to keep skin well hydrated. As far as diet and acne is concerned, the association is debatable. Dairy products and food with high glycemic index
seem to have some link with acne. However if you feel that you develop acne after having eggs or chicken, you might be allergic to them. So try stopping them for few days. Take care.
