When buying sunscreen for Junior, choose one that shields his skin from harmful UVA and UVB rays. The former causes sunburn, while the latter can contribute to skin cancer. Also look out for the product’s sun protection factor (SPF) and PA ranking.
SPF measures how long skin is protected from UVB rays and sunburn, while the PA ranking measures protection against UVA rays. Dermatologist Low Chai Ling, medical director of The Sloane Clinic, suggests buying a sunscreen containing an SPF of at least 15.
