Folks often forget that in the United States the active ingredient in sun screen is a drug and needs to meet appropriate quality system requirements. This Warning Letter to Kari Gran, Inc is a case in point.
The whole warning letter is a result of a company not realizing (or thinking they can get away with not having) the need for GMP compliance.
I’m not sure I would draw broader trends around data integrity or anything else from it.
