Unfortunately the 1970 version I got is just too harsh for me. I emailed the company to let them know, and one representative simply sent me a link to the return policy and said only “this is our return policy” (which of course says if I’ve opened I can’t return). Honestly I really want to try the non 1970 version, but that interaction really put me off. It’s a reasonably expensive product so just buying another bottle, while I still have the entire old, doesn’t feel like the smartest thing to do. Additionally having a representative send me a dismissive link is making me reconsider p50 altogether.
