What does PA rating mean?
PA is a short term for ‘Protection grade of UVA rays.’ It is a significant distinction because SPF protects your skin only against UVB rays whereas PA protects only against UVA rays. These two rays are equally harmful but in different ways. This is what PA rating means:
• PA+ : Some UVA protection
• PA++ : Moderate UVA protection
• PA+++: High UVA protection
