Daily sunscreen

High-SPF sunscreen on exposed skin every day, not only at the beach

Applying a broad-spectrum, high-SPF sunscreen to exposed skin every day, whatever the weather, rather than only on beach days. Dermatology bodies frame it as the habit with the best evidence for lowering skin cancer risk and slowing visible aging. Cumulative exposure decades earlier is what shows up later, which is why people who grew up outdoors without it now talk about it so insistently. A tube costs a few dollars and lasts weeks.
