yeah seems like it kind of removes alot of oils and lubrication in the body and that is good if you have too much oil in the skin/pores but then it can also remove the fluids in your joints, so not good for performance and you can develop athritis if on it for too long
The way the skin can look initially can be absolutely brutal, like keep this person away from me LOL.
Maybe not interesting to most but I had to look up the proposed mechanisms. As I'm getting older I'd like to get ahold of some Retin-A cream but it's Rx and haven't bothered to source it. Collagen production, thicker skin, less sagging and wrinkles.
