Placeholder. American sunscreen is widely considered inferior to European, Japanese, and Korean sunscreen by dermatologists themselves — not because the US lacks the technology, but because the FDA has left next-generation UV filters like Tinosorb and Mexoryl awaiting approval for years while other countries approved them long ago.
What we've found so far: Tinosorb S/M and Mexoryl SX/XL have been standard across EU, Japan, and Korea for years-to-decades but remain FDA-unapproved; UAE-based retailers now build entire business models around importing Korean/Japanese sunscreen specifically because of this gap.
Open research: FOIA the FDA's sunscreen-filter approval backlog and timeline; interview a dermatologist and an FDA official (or former official) on the regulatory bottleneck specifically.
