Sunscreens: how to use them

Korean sunscreens are known for light, serum-like textures that don't leave a white cast. Apply generously as the last step of your morning routine and reapply during long days outdoors. Look for broad-spectrum protection; Korean labels show UVB as SPF and UVA as PA (PA++++ is the highest).
