Heat gun. ONLY apply heat from the INSIDE. I did it on my rear bumper cladding a while back and it was not much of an issue, but takes a bit longer to get it just right since this material is thicker than your average bumper cover.
Yours might take some extra attention since it is right on the lens crease. Look for breaks/tears in that crease line on the inside. A heat gun and some resin should be able to treat it so it doesn't worsen anyways.
