Skin allergy on body. Please suggest!

Hi, I am 29 male from delhi. Since, many years i am suffering from skin problem. I have small acne mostly on my face and back. I wash my face regularly and i keep myself clean. But, still i have lots of them which are itchy. I request you to please suggest me a remedy or do i need to consult a dermatologist. One of my other problem is allergy due to fabric dust. As, i have a business in which i am required to go through lots of checking work of fabric. But when ever i do my work i get itchy nose and sneeze. Then i take critzine medicine for allergy and next day i am all back to normal. I am fed up of taking this medicine. Can i get a permanent relief from it or is there a homeopathic medicine for it. Please suggest Thanks
