Headline: UNCAPTIONED: How to Choose the Right Sunscreen for Effective Skin Protection
Caption: How to Choose the Right Sunscreen for Effective Skin Protection. The most important number on sunscreen bottles is SPF (sun protection factor), indicating how much UVB radiation is blocked. SPF 15 blocks about 93% of UVB rays, while SPF 30 blocks 97%, offering greater protection for longer periods. The British Association of Dermatologists recommends sunscreen with SPF 30, along with shade and protective clothing, for satisfactory protection. Sunscreen should be reapplied at least every two hours, regardless of SPF, to maintain protection. Many sunscreens have a star rating from 1 to 5, which indicates how much UVA radiation is absorbed compared to UVB. UVA radiation causes skin aging and pigmentation, while UVB causes sunburn and is linked to skin cancers like basal cell carcinoma and melanoma. Ideally, choose a sunscreen with both a high SPF and a high star rating for comprehensive protection. Sunscreen effectiveness is reduced when not applied correctly or if it rubs off due to sweat or water exposure. Sunscreens should not be used past their expiration date as their effectiveness may diminish over time. ”Extended wear" sunscreens may claim up to eight hours of protection, but experts recommend reapplying every two hours to ensure full coverage.
