Nowadays millions of people suffer from different skin diseases. These may be dermatitis, eczema, psoriasis and of course acne. Acne is one of the most widespread disease on Earth. Most people think that acne is a temporary condition that passes with age. But actually it is a serious skin disease that needs to be treated. If acne is not treated it can lead to many unpleasant complications. Acne is an illness of oil glands. Skin contains pores (narrow holes) that connect to oily glands through specific canals called follicles. Sometimes these follicles are clogged up with dead cells and sebum(oily substance produced by oily glands) then skin inflammation occurs.
