Why Babies Need Sunscreen Even More in Winter
Parents assume winter means less UV risk. But your baby's already-thin skin (20-30% thinner than yours) faces hidden dangers:
Snow acts like a mirror
Fresh snow reflects up to 80% of UV rays back onto your baby's face—compared to just 15% from sand. That means double the UV exposure.
Higher altitude = stronger UV
For every 1,000 feet in elevation, UV exposure increases by approximately 10%. Winter mountain trips can be especially risky.
UVA rays don't take winter off
UVA penetrates through clouds and windows year-round. These are the rays responsible for long-term skin damage and skin cancer risk.
Your baby's developing skin can't defend itself the way yours can. That's why pediatricians recommend daily mineral sunscreen—even when it's cold outside.
