What Studied

Not a study. This is a regulatory Q&A from the FDA detailing the current U.S. OTC sunscreen labeling rules. It covers what counts as broad-spectrum, how water-resistance must be expressed, and the SPF threshold tied to the appearance-of-aging claim.

Main Findings

The page establishes that products meeting the FDA's broad-spectrum test at SPF 15 or higher may carry the cosmetic-appearance claim of helping reduce the appearance of skin aging caused by the sun. Products that are not broad-spectrum, or that fall below SPF 15, may not. It also defines water-resistance labeling (40 or 80 minutes) and prohibits unqualified terms like "sunblock," "waterproof," or "sweatproof."

Why It Matters

For a daily-SPF Question, this regulation is the reason "broad-spectrum" matters more than any single SPF number. It is also the regulatory anchor for the cosmetic-appearance scope — appearance of premature wrinkles, dark spots, and photoaging — that this Question stays inside per Cross-batch Rule 4.
