Hyperpigmentation scars can be the result of many things. For instance, they tend to occur after a breakout of acne lesions or chicken pox. Once the initial lesion has healed, it can leave behind a dark spot on the skin, which may look like a scar. Thankfully, it's not a scar, but it can take up to a year to fade away on its own, which is why many people wish to remove hyperpigmentation scars using other means to speed up the process.
Use a SPF 30 sunscreen whenever you plan on going outside. This will protect your skin from the sun, but it also protects your hyperpigmentation scars. Hyperpigmentation marks will darken even more when exposed to the sun, so protecting yourself will speed up the treatment process. It will also protect you from any sun damage that could result from using lightening creams to get rid of these scars.
Apply lemon juice to your hyperpigmentation scars a few times a week. With clean hands, apply lemon juice directly to your hyperpigmentation scars. Let the juice soak in and completely dry before rinsing your skin well.
Apply an over-the-counter cream to your hyperpigmentation scars. The main ingredient in these creams is usually hydroquinone, which is a bleaching ingredient. When applied to your hyperpigmentation scars regularly, it will slowly remove the pigment and help them match the surrounding skin.
Apply prescription creams to your hyperpigmentation scars. Your dermatologist will likely prescribe a retinoid cream like tretinoin to treat your scars. Apply this cream after cleansing your face once per day. Use a small amount to cover your entire face. When applied diligently for several weeks, you should notice your hyperpigmentation scars start to fade.
