The strongest SPF available in consumer sunscreen products is typically SPF 100. However, SPF values above 50 offer only marginally more protection than SPF 50. It's more important to apply sunscreen liberally and reapply every two hours or after swimming or sweating for optimal protection. Look for 'broad-spectrum' labels to ensure protection against both UVA and UVB rays.
