Acne is usually categorized into two main groups: Non-inflammatory acne, also known as comedones, includes blackheads and whiteheads. Inflammatory acne, which includes papules, pustules, nodules and cysts, results from the body's fight to contain an infection. By this information, you can classify what group does your acne belong. I'm not sure but yours seems to fall in non- inflammatory since I can only see blackheads and whiteheads. Oily face causes acne. So, prevent skin from producing oil, wash your face twice a day to remove excess oil so it does not clog your pores. Use a deep cleaning facial mask as needed to remove excess oil from skin. Or you can use natural treatments to remove oil and acne.
