What's Al Pacino's Anti-Aging Secret?

Al Pacino is one of those Hollywood men who seems to have aged well. Does he just naturally have a tendency to look young or has he engaged in treatments that have kept his relatively youthful appearance (and kept him in the spotlight of leading roles)? Any sign that he's gotten cosmetic work done is just speculation but some people hypothesize that he's been getting treatments of various kinds for years. Make Me Heal recently suggested that he's had a series of procedures done over the course of the past 10+ years. They believe that he's recently had some intensive plastic surgery done. But they also think that he's been getting non-invasive or minimally-invasive anti-aging work done since the early '90's. Their suspicions lean in favor of laser resurfacing and dermal fillers. They say that refreshed eyes, tight skin and an absence of wrinkles are the indicators that lead them to believe that this is true. Perhaps. Pacino isn't saying anything about it.
