Beef tallow
Rubbing rendered beef fat on your face is having a moment. When researchers analyzed the social posts promoting it, the claims 'largely lacked cited evidence,' most posters had something to sell, and almost none were clinicians. There are no good clinical trials behind it, and heavy fats can clog pores on breakout-prone skin. Your moisturizer does not need to have been a cow.
