Incision/Scar Line from Upper Blepharoplasty and the Sun?

Any scar that is still red in color, will pigment abnormally if exposed to sunlight so that should be an easy way for you to know how long to avoid direct sunlight.

Having said that, a blepharoplasty incision is very well hidden and the risk of abnormal pigmentation is low, except for possibly the outside and inside corners of the eyelid where the skin fold is absent.

I certainly would not recommend suntanning during this time and it would be best if you wore protective sunglasses when outside.

I recommend being diligent about sun protection with sunscreens and limitation of sun exposure for any exposed incisional scar for 6 to 12 months.  A good indicator that the scar has matured is when the color is no longer pink and matches the color of the surrounding skin.

I recommend that my patients avoid sun exposure to any surgical incision until the scar has faded.

As long as the incsion is red minimize your sun exposure.you will just keep it red longer.

Scars continue to mature over the course of 6 months to a year.  During this time period, it is helpful to limit direct sun exposure, by wearing sun block.  Sun exposure could cause a change in the scars coloring, such as darkening and making its appearance more obvious.  Blepharoplasty scars typically heal very well, but sun block is always a good idea as well as sun glasses for protection of the scar, but also for the your skin and eyes.
