This is very interesting. While I do not claim to know everything the skin rejuvenation cannot be a standalone way of reversing aging and lasting longer, Renal failure, heart attacks, cancer, Alzheimers. these are things we cannot treat simply by "yes we made your skin look young so now your kidneys can synthesize electrolytes and you wont die" to me, this seems like human ego and vanity yes modern medicine can make you look younger than you are (William Shatner) but I have been in the medical field for 5 years and through ICU, VA Hospitals and cancer wards I have found absolutely no evidence that would say rejuvinate the skin, fix the organ failure that no matter how hard we try will still happen with old age, your immune system will eventually quit your body will eventually just stop. regardless of how young you look.
