선크림만 바르면 피부 안좋아졌던 이유. 화장품 연구원의 선크림 총정리

Hello, Cookies! Actually, I filmed this video at 11 PM after returning home from an outing all day... So looking at it now, my hair is greasy and my makeup is all worn off haha. Since I filmed it when I was so exhausted, I guess I was a bit out of it, so there are some parts in the video that lack context and explanation 🥹. To avoid any misunderstanding, I’ll explain a little more here! 📌 All organic materials are bad : ❌ Most cosmetic ingredients are organic (oils, moisturizers, etc.). I want to clarify because it might sound like I'm saying organic materials are unconditionally bad! The reason the presence of organic materials is important in sunscreens is because they have the role of blocking UV rays. They need to receive and process the very strong energy known as UV rays. During this process, the molecular structure of first-generation organic sunscreens can break. If these broken fragments combine with skin proteins, it can lead to an allergy triggered by the immune system attacking. On the other hand, the molecular structure of inorganic sunscreens does not change. In other words, there is no mechanism to trigger an immune response. This is why mineral sunscreens are the mildest. So, to be precise, it is not that they "react because they are organic matter," but rather that "since they are organic molecules tasked with absorbing UV rays, there is a possibility of structural change"—a more accurate description! 📌Timeline 00:00 Sunscreen Summary 00:20 Why Asians Look Younger Than Westerners 01:09 The Effects of UV Rays on Our Skin 02:07 How to Read the SPF 2:22 Types of UV Rays (UVA, UVB, UVC) 03:52 Why You Should Apply Sunscreen Even on Cloudy and Rainy Days 4:07 What Is SPF 50? 5:14 What Is PA++++? 5:52 How Much Sunscreen Should You Apply?
