After acne clears, many people can be left with red spots, or what we can post inflammatory hyperpigmentation. Fortunately, these spots will usually clear between three to six months. However, people with more severe acne may experience scarring. There are very effective treatments for scarring nowadays, these include skin needling or fractionated laser. It's really important to talk to your doctor about these treatments. For people with mild to moderate acne I would recommend an over the counter preparation such as Papulex. For people with more severe acne I recommend talking to your doctor about specific treatments which they may require. For people with more severe acne, it's great to know that Papulex can be used in conjunction with other acne treatments, which may have been prescribed by a doctor.
