I've noticed from photos I'm looking noticeably older than a few months ago (poor diet and sleep maybe - I've improved on this). I'm in good health and exercise. I don't know anything about the mechanisms of facial aging, but I would really like to restore that youthful look. What do you think is causing me to appear older and what treatment would you recommend? The ones I've so far thought about are fillers (which one?), chemical peel, laser , RF.
