Why Skincare Safety Is So Confusing | Dr. Danny Guo

📖 Full written guide with sources: https://drdannyguo.com/library/skincare-myths Most people think “toxic” means dangerous. But that is not how ingredient safety actually works. A lot of skincare fear comes from confusing hazard with risk. Hazard means something could cause harm under some condition. Risk means how likely that harm is to happen in real life, based on dose, exposure, route, frequency, and who is using it. This is where EWG and regulatory agencies like the FDA or Health Canada often feel like they are saying completely different things. EWG tends to focus more on hazard. Regulators focus more on real-world risk. That difference changes everything. In this video, I break down why skincare safety ratings are so confusing, why “toxic” is often used in a misleading way, and how to think about ingredient safety more clearly. ✅ Hazard Can this ingredient cause harm under any condition? ✅ Exposure How much are you actually exposed to? ✅ Route Are you eating it, inhaling it, injecting it, or applying it to skin? ✅ Vulnerability Is this a healthy adult, a child, pregnancy, damaged skin, or another higher-risk situation? Good skincare safety conversations should not be based on fear. They should be based on context. ABOUT DR.
