Alcohol Denat.: K-beauty ingredient guide 변성알코올
⏱ 1 min read
⚡ Quick answer: The single most argued-about line on a Korean sunscreen label. Denatured alcohol is why that sunscreen feels like nothing and vanishes under makeup — it flashes off and leaves the filters behind. It genuinely stings compromised or sensitised skin. The claim that it damages a healthy barrier at cosmetic levels is far shakier than the internet suggests.
