Why did my scar turn brown?

    Your scar likely changed color because it was exposed to the sun. This sensitive skin is more likely to burn or change in color if exposed to the sun before fully healed.

    Ultraviolet light from the sun will cause a scar to darken and make cause hyperpigmentation. Always wear sunblock of at least spf 25 if possible for one year after the scar develops.

    Your scar was probably exposed to the sun. The skin from a wound is sensitive as it is healing and burns easily when exposed to the sun. Before you go out in the sun, you should apply sunscreen to your scars and cover them with clothing or a bandage.

    Scars typically turn brown in response to sunlight and the UV radiation found in the sunlight.  Often lasers can be used to treat the hyperpigmentation in scars and reduce it.
