Скачать или смотреть SPF vs Amount: Does The Label Even Matter? Why You Shouldn't Throw Out Your Sunscreen Just Yet

Point blank: there's a lot going on in the skincare game right now around #sunscreen, and there's a lot of things in limbo as we try to figure out what actually does what it advertises to do, and what is tea and what isn't. As the dust settles around this, I wanted to bring up a point of interest that came up recently in research that I thought would be worth sharing.
