Sure, this is the most extreme of the recommendations here, but if you are serious about helping your skin cells function at their peak, platelet-rich plasma injections are the most sophisticated (and natural) integrative treatment available. You might hear facial injections and immediately think of filler or botox, but these injections are entirely naturalbecause it comes from your own blood.

A vial of your own blood is drawn, put in a machine called a centrifuge, which separates the platelets from the rest of the blood cells (white and red). Platelets, which contain growth-factors, are in charge of recovery and inflammation in the body. When an area of the body is damaged (i.e.: premature aging from oxidative stress or environmental aggressors, like pollution), that area needs more repair cells, but sometimes it's hard for the body to get those cells to said location. So that's why you inject (or use acupuncture or via microneedling) a concentrated amount, so the platelets can hyper focus on damaged and aging skin cells. The result is skin that is better able to heal itselfresulting it smoother lines, more even texture, and improved tone.
