Heatwave India: Decode SPF, PA Ratings for Ultimate Sun Protection

• SPF (Sun Protection Factor) measures protection against UVB rays, responsible for sunburn and long-term skin damage.
• Dermatologists recommend SPF 50 as the baseline for outdoor use in Indian conditions, with reapplication every two hours.
• PA ratings (PA+ to PA++++) measure protection against UVA rays, which cause pigmentation, melasma, and premature aging.
• The PA rating, not just SPF, is crucial for preventing tanning; PA++++ offers the highest level of UVA protection.
• Apply about a quarter teaspoon for the face, 15-20 minutes before stepping out, and reapply every two hours when outdoors.
