Beauty Tips For Body Care
I have never had a problem with my skin , it was normal, no zits or acne while I used to use cleansing foam , moisturiser a couple of times a week and scrub and a mask once a week. A couple of weeks ago I had a number of zits low on my cheek. So I started using cleansing foam twice a day and moisturiser every morning. The zits didn't go away but they were not really irritated , I also noticed that my skin was starting to get a little oily. After using the cleaner, my skin felt stiff and dry , while the moisturiser made my skin feel oily. I went to a dermatologist and she said I had acne because I had a problem with my period the last two months. She gave me a cleaning foam for oily and prone to acne skin and a cream to apply topically After using these for 4 to 5 days my skin broke out , became itsy and oily What went wrong?
