The ingredient people complain about the most is the single one that'll make the biggest difference in your skin — and no, it's not a retinoid or a fancy peptide. It's your sunscreen.
This week we're getting into why SPF is the highest-leverage thing you can do for your skin (prevention is cheaper and easier than reversal), the difference between UVB and the UVA rays nobody talks about, chemical vs. mineral without the fear-mongering, what those "sunscreen in your bloodstream" studies actually found, and the new filter the FDA finally approved in June — what it is, and when you'll actually see it on shelves.
No demonizing, no overclaiming. Just the nuance, from a friend who did the research so you don't have to.
