What happens if my facelift scar is exposed to sun?

Scars darken. Scars may darken in uv light. Also any bruises may cause a darkening of the skin. It is beat to keep scars out of the sun till they mature and lose their red color.

Get worse. Most scars will not heal as well as possible unless you protect them from the sun. Your skin type will determine how well your scar will ultimately heal. Fair-skinned redheads will have scars that stay red for a long time and darker-skinned individuals may lay down darker pigments in their scars. Use a sunscreen with titanium or zinc oxide and cover it from the sun. Massage will also help. Be well.
How long ago? Fresh scars can turn brown if exposed to the sun. I teach my patients to use sunscreen on their scars for the first sun season after the surgery. Of course, you should really be using sunscreen on any parts of your body that you don't want to get wrinkled and have skin cancer cut off of later, anyway! good luck and use your sunscreen!
Facelift scar. If this was an incidental event, it should not be a problem. However, going forward, you should do everything you can to prevent a "fresh" facelift scar from sun exposure with out protection.
Darkening. Any fresh scar that is exposed to the sun can become hyperpigmented or darker.
Facelift scar. Avoid excessive sun exposure as your scar is healing to prevent pigmentation in the scar.
UV light and scars. Uv light is not good for scars. It tends to make them darker. If you get surgery, make sure you take steps to avoid uv exposure. Talk to your experienced facelift surgeon as they may have particular guidelines and modalities to help.
Uneven coloration. The skin right at the location of the facelift incision is not "normal" for several months. If it is exposed to sun or any ultraviolet light (uv) it will not "tan" evenly with the surrounding skin. It may tan darker than the surrounding skin, but in some cases, it may be lighter than the surrounding skin. Best to use a physical uv sunblock (zinc oxide) for the first 6 months after facelift.
Darkening. Sun will cause significant hyper pigmentation and darkening of your scar which will make them more pronounced.
Sun Exposure. Exposing your facelift scar to the sun is not a good idea, as it will delay healing and cause increased redness. For more information on post-surgery instructions, visit: http://www.Facialplastics.Info/facelift.Html.
Increased scarring. Be very careful following surgery to keep the incisions protected from the sun for even the first few months. Sun exposure can result in more visible scarring compared to well protected incisions.
Depends. If the scars are fresh and the redness has not fully resolved then strictly avoid sun exposure, or pigment abnormalities may ensue. After that they should be ok. Yet, understand sun exposure contributes to skin aging, so sunscreen on the face is always a great idea!
Discoloration. Any time a recent scar is exposed to the sun it may discolor. Most commonly, the scar will darken due to an increase pigment. Darker complextions are at greater risk of pigment formation. You can avoid this problem by wearing protective clothing and by frequently applying a broad-spectrum sunscreen that blocks both uva and uvb rays.
They may look worse. Early wounds exposed to uv radiation may become hyperpigmentation or more red making them more noticeable. In older scars, lack of pigments may make the scars relatively fair or faded in comparison to the normal surrounding tanned skin.
