Exposing a fresh scar to the sun can often result in an irritating itching sensation. But it can also damage the scar in more lasting ways, too, affecting its color and appearance. For this reason, it's wise to protect recent scars with clothing or a layer of sunblock.
Scars
Scars are part of the body's natural response to injury. The way in which scars develop and change varies, depending on the individual and the extent of the injury. It can take 12 to 18 months for a scar to “mature,” shrinking and eventually becoming paler and less noticeable. It's during these early months that a scar is particularly susceptible to sun damage.
Reaction to Sunlight
It's common for fresh scars to itch when exposed to sunlight. This is usually a sign that the scar has not yet fully healed and that the nerve endings are still in the process of reforming and recalibrating. Once a scar has successfully matured, the nerve endings should settle and the scar will be less likely to itch. Direct sunlight also can affect your scar in more serious ways. Scar tissue may sunburn faster than healthy skin and a sunburned scar can become permanently discolored.
Protection
Take sensible precautions to protect any recent scars from strong, direct sunlight. Wear garments that provide coverage and don't spare the sunblock. Use lotions with a sun protection factor, or SPF, of at least 15. If you've had cosmetic surgery on your face, wear a broad-brimmed hat and big sunglasses.
Treatment
A daily massage regimen can help alleviate sun-related itching or other forms of discomfort. Using a neutral moisturizer, massage the scar several times a day for five to 10 minutes. To do this, gently work the skin around the damaged tissue. This keeps the scar flexible and prevents it from locking on any subcutaneous matter. Your health care provider can advise you as to when your scar is strong enough for you to begin daily massages.
