on face /neck/back and front are all due to infection to pilosebaceous glands blocking the pores and preventing the secretion of sebum leading to inflammation,redness/pain/enlargement.We call it Acne
Due to high temperature in the new country it will get aggravated.
(1)A course of Antibiotics-Broad spectrum-Ex-Doxycycline(2) Cindamycin local application in gel form (3) Astringent/peroxide based cleansers(4)Pealing agents such as Isotritinoin Cream(5)anti inflammatory if pain is intolerable.
the above course along with removal of blocking comedones will help you to get over the present problem.
