"If you think the FDA has been slow at approving new coronavirus tests just look at their process for approving sunscreen products.
EWG: The FDA first began working to update sunscreen regulations more than 40 years ago. In February 2019, the agency at long last issued a proposed set of final rules, but they were never adopted.
According to EWG, the Environmental Working Group, the FDA has been too slow to test old ingredients for safety and too slow to allow new ingredients on the market thus leaving us with sunscreen products which are neither as safe nor as effective as they should be. In particular, Europe has better sunscreen protection than the United States."
