Are you taking care of your kidneys? Are you staying properly hydrated? Dehydration alone will cause the skin to wrinkle prematurely. Iodine supplementation puts the kidneys through a workout and if your kidneys are not up to the task that will definitely show in the skin. Generally this will manifest as severe "detox", "brominacne"... but I would imagine that increased wrinkling could very well be brought on by the increased workload on the kidneys...
