I'm not going to tell you what's safe for your body, because that's a conversation with a doctor who knows your history. What I can tell you is that in ten years of reading this stuff the pattern is identical every time: preliminary paper, alarming headline, much duller follow-up that nobody shares.

Worth adding that most cheap ones do nothing against iron specifically. You want a KDF-55 medium rather than plain carbon.
Japanese ones also carry the PA rating for UVA, so you get a second number to compare rather than trusting the SPF figure alone.
Terse: buy the six-cup, grind finer than french press but coarser than espresso, take it off the heat early. Three years in, no regrets, no upgrade path needed.
Noticeably heavier than a plain nylon 30L, and it's the structure and hardware doing it, not the fabric. Pick one up in person if you get the chance, or be prepared to eat return shipping on a bag this size.
Blotting paper first, then reapply. Putting sunscreen on top of an existing oil layer is exactly why it rolls off in those little pills. Twenty seconds with a blotting sheet and mine sits properly for the rest of the afternoon.
Chelating fixed it for about four days and then it came back. So, minerals?
I labelled things in my kitchen with sticky notes like a cliche and it worked embarrassingly well.
Careful with that analogy past the first month. Types tell you when you are wrong immediately, whereas a wrong proof looks exactly like a right one until somebody reads it. That delay is the actual difficulty and it is why people need a marker or a study partner early.
True for a finish that is still there. On a three year old commuting jacket the finish is usually worn off the shoulders and forearms rather than just flattened, and heat cannot bring back what has abraded away.
One practical thing: check the expiry date. If you're finishing bottles late, buy smaller ones. Mine used to go off before I got any value out of them and the texture changes noticeably before the date does.
The honest version: UVB barely gets through standard window glass, UVA gets through considerably more. So the indoor argument isn't zero risk, it's much less risk than the bottle's marketing implies. I wear it on days I'm outside at lunch and skip it on genuine dark-commute winter days, and my dermatologist shrugged at that plan.
It works, and it works better on chisels and plane irons than on knives, for a structural reason. A chisel has a wide flat bevel that sits on the abrasive and registers itself, so the paper cannot do much wrong. A knife bevel is narrow and you are holding the angle freehand while pushing along the edge, and any give in the paper lets the abrasive wrap slightly over the apex and round it. Two fixes: stick the paper down properly with spray adhesive or a wet film of water so it cannot lift, and pull the edge rather than push it into the paper so you are not digging in. Do that and you will get a genuinely sharp kitchen knife off 2000 grit.
Reaching forward is exactly when it feels wrong and I have never once photographed that.
Whatever you land on, keep a second bottle at the office. The reapplication you'll actually do is the one where the bottle is already sitting on your desk.
Approvals are all there with dates. The scope discussion that led to the last milestone is unfortunately in email.
The one paragraph summary after every call is going in immediately, whatever happens with this one.
Bring proof from outside the platform, because the platform is not the only place trust comes from. A simple page with three worked examples, before and after, plus two former colleagues willing to be named as references, closed more work for me than my review count ever did.
Consistency beats dose more than people expect. I was taking mine 'daily' and when I actually counted the blister packs at the end of winter I'd taken it about 60% of days. A pill box left on the dinner table fixed my numbers without changing anything else about the product.
This solved a problem I had chased for a year in the wrong place. I had been widening shoulders that were already the right width.
The sneaky one is the drive home. A west-facing windscreen in summer puts more UVA on one side of your face than the entire office day did, and nobody reapplies for a commute.
Five weeks and expecting it to be permanent was probably the mistake then.
