Decoding SPF: Meaning, Difference Between SPF 30, SPF 50 — Pnk Beauty
SPF, or Sun Protection Factor, indicates a sunscreen’s effectiveness against UVB rays, which cause sunburn and skin damage. SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks around 98%, offering slightly more protection. Although the difference seems minor, SPF 50 is ideal for prolonged sun exposure or sensitive skin. However, no sunscreen provides 100% protection, so reapplication every two hours is essential. Always opt for a broad-spectrum sunscreen to guard against both UVA and UVB rays. Pnk Beauty recommends incorporating SPF into your daily skincare routine for healthy, protected skin.
