He just keeps getting better with age!

"It doesn't look like he has had much [plastic surgery]. You can see that his eyelids are [now] heavier, which goes against eyelid surgery and you can see some banding in his neck which goes against a facelift or neck lift," Dr. Miller said.
"If anything, he may have had some Botox and fillers injected to help maintain a little more youthful appearance and keep some of the wrinkles and facial folds away," Dr. Miller continued. "The face is a little thinner, which is what happens with age, and his eyebrows are darker — possibly dyed as needed for a role."
Dr. Mardirossian similarly suggested John may have gotten a hair transplant, Botox or fillers, and a neck lift.
