I've used Korean sunscreens for four years mainly because the textures beat anything I can buy locally, and I'm now unsure what to trust after the run of testing stories. I'm not trying to relitigate the whole thing. I want to know what people are actually still buying and whether you changed how much you apply. Budget is about $20 a bottle and I go through one every six weeks.
I didn't change brands, I changed the quantity. I was applying maybe half of what the lab test uses. The testing standard is 2 mg per square centimetre, which for a face and neck is a genuinely uncomfortable amount of product. Applying properly almost certainly did more for my actual protection than any brand swap would have.
I moved to the bigger Japanese houses instead, mostly because their testing chain hasn't had the same run of stories attached to it. Textures are close enough for me and it removed the decision entirely, which was worth something on its own.
Japanese ones also carry the PA rating for UVA, so you get a second number to compare rather than trusting the SPF figure alone.
Blunt: no consumer can verify SPF. What you can do is buy from a company large enough to have something to lose, apply enough of it, reapply when you're actually outside, and wear a hat. Everything past that is vibes and packaging design.
New to this area. Is there any published list of which specific products got retested and passed? Every article I find names the failures and never the survivors.
For the Australian round there is a named list of the four that met or beat their label. For Korea it's messier and much of it is still in progress. I'd be careful with any blog claiming a definitive safe list.

Short version of what happened: a run of products came under question, several Korean brands pulled products or issued refunds, and then this July there was a fresh round of noise about Daiso's line after an independent tester published his own results. Daiso disputed those results and said it is going back through a state-accredited lab. So "Korean sunscreen is fake" is too strong, but "the testing pipeline had real problems" is fair.

Clearest summary I've read and it matches what I half-remembered. Appreciate you not overclaiming in either direction.

Worth noting the same category of failure showed up in Australia through a completely separate testing chain, so this isn't a Korea problem so much as an SPF-testing-is-hard problem.
