How the claim framework works ->Strongest version
Tanning beds are not a safer substitute for perineum sunning or sunlight; UV-emitting tanning devices increase dermatologic risk and are classified as carcinogenic exposures.
Weakest version
The evidence does not support turning this into a universal claim for every person or context.
What would change our mind
Larger, better-controlled, independently replicated evidence in the relevant population and outcome lane.
What supports this claim
Strong human evidence
Canonical sources and linked study records currently support this claim framing.
What weakens or limits this claim
Limitation
