How long should you keep your scar out of the sun?

The fresher the scar the more you should avoid sunshine on it. But even when the scar is older it is good to keep it out of the sun. The solar radiation will do damage to the scar tissue. I kept my scars out of the sun for at least the first 1,5 years. I used patches or sometimes a very thick layer of cream to cover the scars. I preferred patches because this was a more secure method.

When scars are in their final state. This means they are not so red anymore and less raised. Then sunshine can help with the scar color blending into the surrounding skin.
