Acne is a very common skin condition that happens when hair follicles under the skin become clogged. It is generally caused by the same factors: oil, dirt, dead skin cells trapped in pores. Some types of acne can cause redness and irritation during the growth stage. Once the acne is gone and the dead cells of the scab dissolve there is a chance it will leave a scar behind. There are certain ways of reducing redness and swelling while we still have acne and also mitigating the risk of getting scars as a result of healing.
