Beef tallow… as sunscreen? Absolutely not.⁠ ⁠ As a board-certified dermatologist, I have to shut this down real quick. Beef tallow has zero SPF. It doesn’t protect you from UVA or UVB rays—in fact, using it can make sun damage worse by intensifying UV penetration.⁠ ⁠ If you want a more “natural” option, go for a mineral sunscreen with zinc oxide or titanium dioxide. Just please don’t skip SPF. Science matters. #spftruth #skincaretips #dermtips #sunprotection #beeftallow #skincancerawareness
