I had gone gym for first time previous year . From then , I have got some skin problem . In my back , shoulder , stomach and in face , there are spots like acne . Sometimes​ it gets too bad , sometimes it becomes normal . But acne spots always remain in above described body parts . I had already consulted doctors for it . They had suggested some gel like Nilac and anti bacterial powder like nycil . But my problem is not solved completely . I am unable to find out the reason behind it . Whether it is because of gym or there is some another reason . Please help . Thanks in advance .
