Sunscreen works by minimizing the appearance of a scar and preventing hyperpigmentation, according to WebMD. A sunscreen that blocks UVA and UVB rays is the recommended choice. Silicone gel sheeting is also placed on a scar to help fade a scar or prevent it from worsening. These sheets are available through a pharmacy or a dermatologist's office. Bleaching creams are also effective in helping to treat darkened scars and lighten their appearance. Concealer is used to minimize the appearance of a scar. There are also many over-the-counter medicines and products that purport the ability to minimize the appearance of scars. However, these are not recommended.
