The SPF Number Is Lying to You | Sunscreen Science for Black & Brown Skin

Most people choose sunscreen by one number: SPF. But SPF is essentially a sunburn stopwatch — it measures how long until your skin shows a visible reaction to UV, and that test was calibrated around a signal that is much quieter on darker skin. So the biggest number on the bottle tells you almost nothing about the damage that actually matters for melanin-rich skin.In this episode we read the back of the bottle instead of the front. We get into why UV is only about 5% of sunlight, what the other 95% — visible light and infrared heat — is doing to your collagen and firmness, and why "Black don't crack" is only half the story.We cover the SPF stopwatch and who the test was built for, the anti-aging and free radical claims sunscreen brands lean on, UVA vs UVB and the damage you accumulate without burning, the PA rating and UVA mark hiding in the small print, broad spectrum, iron oxides and tinted sunscreen for visible light protection, why Korean and Asian formulations often sit better on deep skin, and a simple back-of-bottle checklist for choosing sunscreen for Black skin.Free guides at blackskinscience.com.This content is for educational purposes only and does not replace professional medical advice.
