Why should I choose sunscreen with both SPF and PA?

A sunscreen with both SPF and PA provides comprehensive protection. SPF (Sun Protection Factor) shields against UVB rays, preventing sunburn, while PA (Protection Grade of UVA) protects against UVA rays, which contribute to aging and skin cancer. Look for a sunscreen SPF PA combination for broad-spectrum defense. This ensures you're safeguarding your skin from both types of harmful UV radiation, promoting healthier, more youthful skin in the long run.
