You've known this for twenty years — it's why the bottle says BPA-free, and why somebody told you not to microwave food in the takeaway tub. So go and look at what in your kitchen gets hot and is made of plastic. The pod the coffee brews through. The tank in the kettle. The tub in the microwave. The lid on the cup you carry to work.
Once those chemicals are in you they generate oxidative stress. Not in bursts — steadily, at low level, everywhere the blood goes, including the layer under your face where collagen is made and unmade.
And you already know what that does, because it's the reason there's an antioxidant in every serum you own. UV hits skin, UV makes free radicals, free radicals switch on the enzymes that cut collagen apart. That isn't a fringe theory — it's the standard account of how the sun ages skin, and it's been recited at you across a counter since you were twenty-five.
Same fire. Different source. This one doesn't care about a hat, it doesn't stop when summer ends, and it's still burning at three in the morning with the blinds shut.
And before you decide this is something they've escaped: Korea and Japan wrap more of their food in plastic than we do, not less. They're carrying the same load you are. They're just getting rid of it faster.
