La Roche Posay Anthelios Age Correct SPF50 Trends

SPF 50 is a level of protection offered by sunscreen that reflects both UVA and UVB rays to help prevent sunburn and skin cancer. Properly applied SPF 50 sunscreen blocks 98% of UVB rays, making it preferable for those with a history of skin cancer or fair skin. Sunscreens with SPF values between 30 and 50 offer adequate sunburn protection, even for the most sensitive skin. However, experts recommend using sunscreen with SPF 50 or higher for daily use to even out skin tone and achieve a good texture. Choosing a broad-spectrum SPF 50+ sunscreen filters 98% of UV radiation, providing slightly more protection than an SPF 30+ sunscreen. Nonetheless, it is necessary to reapply sunscreen every two hours, particularly if swimming or sweating, for maximum effectiveness.
