【名推理】化粧品にまつわる検定があるらしいので、例題に挑戦してもらったら…

Hello everyone, I'm Motawari Hojo, a dermatologist. I've been learning about skin care on my channel for a long time. I'm a man, and I've been learning how to rebuild my skin. I've learned a lot about how to rebuild your skin and how to treat it. I've been commenting a lot about cosmetics. I found this website today. It's a website called Japan Cosmetic Certification Association. It's called Cosmetic Certification. We're in the middle of a cosmetic project. I thought I'd give it a try. There are six questions in total. I see. Let's go. I'd like you to answer the questions. Let's start with the second question. What is the state of the surface of the earth with the highest reflectivity of UV rays? 1. Asphalt 2. Sand 3. Surface 4. Kindness I think it's kindness. Asphalt is very reflective. The sand is dirty. The surface of the water is bright. But I think it's kindness. You think it's kindness? Yes. Number four is correct. That's great. The reflectivity of UV rays in kindness is 80%. The surface of the water is 10% to 20%. Asphalt is 10%. The sand is 10% to 20%. The reflectivity of UV rays depends on the state of the earth's surface. Skiing makes your skin black. That's right. Skiing burns your skin. It does. It comes from all directions. It comes from the top and the bottom. That's right. Thank you. The first question is correct. Let's move on to the second question. What is the component that acts like a lid so that it does not evaporate the water in the skin? 1. Collagen 2. Amino acid 3. Purified water 4. Vaseline The component that acts like a lid is vaseline. So, number four is vaseline? Yes. Collagen. Yes. Number four is vaseline. That's correct. It's like a box. That's right. This was too easy. Yes. Vaseline covers the skin. The water from the skin is purified. That's right. Collagen and amino acids keep the moisture in the skin. Let's move on to the third question. What color concealer do you use to cover blemishes? I don't know this one. Blue. It's blue. Blue is yellowish. 1. Orange 2. Purple 3. Gray 4. Beige This is a professional question. I don't know. There are red and purple. Red and green. Blue and yellow. What color is closest to yellow? Orange? Beige is different. Purple is... I don't know. Orange. That's correct. This is... I have no idea. I give up. Orange is correct. That's amazing. I see. I was wondering what was closest to yellow. I thought it was blue. I thought it wasn't gray. I think this is closest to yellow. In the case of dark-colored blemishes, if you use a concealer that is the same color as your skin, your skin will turn gray. In the case of blue blemishes, use an orange concealer to cover the blemishes. I talked about this in another video. The color of the skin is uneven. What does this mean? The three primary colors of light are red, green, blue, and yellow. When you look at the distribution of standard deviation, the standard deviation is large. If you reduce the standard deviation, the color unevenness will be reduced. The color of blue blemishes is yellow. If you want to cover blue blemishes, I think it's better to use the color of the blemishes to reduce the standard deviation. I'm talking nonsense because I happened to be right. No, no, no. It's a reasonable answer. That's right. It's not a guess. Thank you very much. The second place is 3-3. Yes. That's amazing. I'd like to move on to the first place. I don't know if the container was dyed with henna. I don't know either. I don't know if the body part was dyed with a suitable color. I don't know. I don't know if this is a cosmetic test. What is henna? Yes. One. Two. Three. Four. I don't know what henna is, but it was dyed. I think it's either a nail or a tooth. Nail or tooth is keratin, so it's either a lip or a cheek. I'll just guess. Yes. Tooth. The second place is tooth. Yes. I'll move on to the next place. Yes. The correct answer is 3-3. It was a nail. That's unexpected. If I had known, I might have used it as a manicure. I'm not sure about that. I've only taken it up to level 3. You can take it for free on the Internet. I see. It's interesting. Yes, it is. I see. The second question. Yes. Which of the following ingredients has the strongest antibacterial effect? If you were to compare the same ingredients and concentration, 1. Methylparaben 2. Ethylparaben 3. Propylparaben 4. Butylparaben Paraben is often used as an antibiotic. Methyl, ethyl, propyl, and butyl. I forgot which one is butyl and which one is propyl. I don't think it's methyl or ethyl. I think it's either propyl or butyl. It's either one of the two. Yes. I think it's butyl. Judging from the order, I think it's butyl. Let's go with butyl. The correct answer is 4. Oh, it's 4. Yes. I knew it was 4. Yes. Paraben is the strongest antibiotic. Yes, you mentioned it earlier. It's a strong antibiotic. It's a single-use, anti-inflammatory, anti-inflammatory, and anti-inflammatory. It's the strongest of the three. Methylparaben is the strongest. I was wondering. The fact that it's a big molecule means that it's scientifically unstable. It's the same as HITER. Yes, yes, yes. HITER is a high-energy substance. It produces free radicals, attacks the opponent, and takes away the opponent's electrons. It takes away the biological stability. H2O is a very simple substance, so it's very stable. I didn't know. I read it every day, and it was 4. Yes. But I think it's almost correct. Yes. Let's look at the last one. You don't have to show the expiration date on the product. It is appropriate if the product is manufactured or imported in an unopened state and the quality is guaranteed for at least several years. Other than the product, it is assumed to be done under appropriate conditions. 1. Half a year. 2. One year. 3. Three years. 4. Five years. I think it should be about five years. It's supposed to be an acceleration test. It's the same for medicine. It's the same for both medicine and cosmetics. You don't leave it for five years and open the lid to see what happens. There is an acceleration test. For example, if you leave it at this temperature and this humidity, it will last for several years. There is an acceleration test. I think it was about five years for medicine. Yes. Of course, it's the one you get with the medicine. It says the expiration date on the drugstore. I think it's valid for three years or more. I think it's more than five years. You don't have to show it, do you? I don't have to show it. I think it's five years. No? Can I go to number four? Yes. Number four. Five years. The correct answer is three years. Oh my gosh. Yes. The expiration date for cosmetics is from the beginning of this year to the beginning of the next year. It indicates that cosmetics must be expired in 1980. It is valid for more than three years in an unopened state. It's more than three years. You don't have to show it. Of course, you don't have to show it even if the expiration date is five years. But it's valid for three or four years. That's right. That was the last question of the first question. I see. It's quite interesting. It's interesting. Yes. But when we talk about this, we can't be responsible for manufacturing without scientific knowledge. In the case of methyl, ethyl, and butyl, we need to know how radical it is. And we need to know the quality of the product. We need to have a lot of scientific knowledge. I think it's a normal test. Yes, it is. I didn't get the expiration date, though. That's true. Everyone, why don't you try it when you have time? Today, I found an interesting website. It's a website for a general public test. It's not a public test. Why don't you try it as a game? As long as you look at the problem, it's not a tricky problem. I think it's good for a general public test. Thank you for watching this video until the end. See you next time. You can take the test for free, so I'd like to take it today. I think this is a very bad problem. In a sense, it's a shock. That's right. My explanation is correct, so you can trust me.
