You are saying that, even if you wear sunscreen and avoid sun burn, the UV exposure will still potentially lead to skin cancer?

I'd like to see the primary research backing that up. Or be told how I misinterpreted your statement.

Yes, 100%. It's the same reason that my kids are able to tan through the same sunscreen application regimen that leaves me pale.

there is also that anything that blocks UV (sunscreen, windows, etc) by definition blocks UVB first and then UVA, and UVA is the one that penetrates most deeply and has few benefits
