Broad-spectrum sunscreen

Broad-spectrum sunscreen protects skin against both UVB and UVA rays, the two types of UV light that reach the ground.

What it means

UVB causes most sunburn. UVA penetrates deeper and drives much of photoaging. Look for “broad spectrum” on the label and an SPF of at least 30 for daily use.

Apply generously and reapply after swimming or sweating. In Canada and the United States, sunscreens are regulated and their labels are checked.
