Acne scars are typically permanent, thus it is important to consult a dermatologist if you are experiencing them. Acne therapy can help to avoid scarring by preventing new spots from growing. It is also important to take care of existing scars by applying sunscreen daily and getting a skin check-up every 1-2 years with your doctor. Pimples are blackheads without the presence of pus. They usually appear on the face near the nose as small bumps that may be open or closed. There may be irritation around the spot but not enough to cause a rash. A cold oil or dry powder spray can be used to treat pimples. Do not use alcohol based products as they will make the problem worse. Pimple holes are gaps between your skin and some of your hairs. Hair goes through your skin when you shave or wax, causing little cuts that grow over time. These holes can lead to bacteria getting into your skin, which can cause acne breakouts in nearby areas. Bacteria feeds on dead skin cells, and when it finds an opening, such as a pimple hole, it grows large enough to be seen by others. Bacteria can also enter your body through open pimple holes so it is important to keep hair off of healthy skin. Wearing makeup may cover up open pimple holes but it cannot heal them up overnight!
