India receives some of the highest UV radiation levels in the world, particularly in the summer months and at higher altitudes. Baby skin has significantly less melanin than adult skin and burns far more easily. Building sun protection habits from early life also reduces the long-term risk of skin cancer — and India's skin cancer rates are rising with urbanisation and changing outdoor habits.
Babies Under 6 Months: Shade Over Sunscreen
For babies under 6 months, paediatric dermatology guidelines from both the American Academy of Pediatrics and Indian paediatric bodies recommend avoiding sunscreen and relying instead on shade, protective clothing, and timing. Baby skin under 6 months is more permeable than older skin, meaning chemicals in sunscreen are absorbed more readily. The best protection for very young babies is physical: full-coverage light cotton clothing, wide-brimmed hats, buggy hoods, and staying out of direct sun between 10am and 4pm.
Babies Over 6 Months: Which Sunscreen to Choose
For babies over 6 months, mineral sunscreens — those containing zinc oxide or titanium dioxide as the active ingredient — are strongly preferred over chemical sunscreens for several reasons. Mineral sunscreens sit on top of the skin and reflect UV radiation rather than absorbing it. They are not absorbed into the bloodstream in meaningful amounts. They are photostable (effective immediately on application). They rarely cause skin reactions. And zinc oxide specifically has anti-inflammatory properties that are beneficial for sensitive baby skin.
Chemical sunscreens (containing oxybenzone, octinoxate, or similar) are absorbed into the skin and bloodstream. Studies have raised questions about the hormonal effects of some chemical UV filters, particularly in developing infants. Until more research clarifies the safety profile, mineral sunscreens are the conservative, evidence-aligned choice for babies and toddlers.
How to Apply Sunscreen to a Baby
Apply 30 minutes before sun exposure to allow adequate adherence to the skin. Use generously — most people apply only 25 to 50 percent of the amount needed for full SPF protection. Reapply every 2 hours and immediately after water play or heavy sweating. Common miss spots: ears, the back of the neck, the tops of feet, and the backs of hands. Avoid applying to the area around the eyes where there is a risk of product getting into the eyes.
Sun-Safe Clothing for Indian Conditions
UPF (Ultraviolet Protection Factor) clothing provides physical UV protection. Light-coloured, tightly woven cotton has moderate UPF. Specially made UPF 50+ children's swimwear and outdoor clothing provides excellent protection and is worth the investment for children who spend significant time outdoors. Wide-brimmed hats that shade the face, ears, and neck are essential. A hat with a 7cm brim all the way around provides the most complete protection for a baby in a pram or being carried.
