肌の老化、原因の8割は紫外線？

Trivia #3: 'The causes of acne are different for children and adults'

You might have a strong image that 'acne = something that happens during middleschool and high school.' However, many people still struggle with acne even after becoming adults. Moreover, adult acne can sometimes hide unexpected health issues. During puberty, increased sebum production clogs pores, causing whitish acne. This can become inflamed, redness and swelling appear around the pores, and in more severe cases, it can become pus-filled. After the age of 20, the influence of female hormones often causes acne around the mouth and chin, especially before menstruation. During the COVID-19 pandemic with prolonged mask-wearing, acne has been harder to heal, causing trouble for many people. Acne can also be caused by internal organ issues, irregular periods, constipation, or diarrhea. If the liver is not functioning well, or organs like the thyroid or adrenal glands are not working properly, red and inflamed acne can suddenly appear. Therefore, if the underlying condition is not improved, acne may not go away. People with atopic tendencies are also said to have a hard time healing acne. In such cases, acne may improve with treatment for atopy, so if your acne doesn’t clear up even after puberty, it’s a good idea to see a dermatologist.

Trivia #4: 'Don’t disinfect a wound, just wash it daily until it heals'

Many of us have memories of having a wound disinfected as a child when we scraped ourselves. However, since around 2000, it has become clear that leaving disinfectants on wounds can cause allergies and impair the body’s natural healing ability. So, how should you treat wounds? First, wash the wound thoroughly with soap and rinse it well with water to remove dirt like mud. After that, cover it with a bandage made of a material called hydrocolloid to prevent the wound from drying out. Using a hydrocolloid bandage helps prevent dryness by using the fluids that seep from the wound.

Trivia #5: "Even if you eat meals full of collagen, it doesn't mean your skin will become plump"

When you go to restaurants, you might see menus that say things like "Packed with collagen!" Eating it can make you feel like your skin will be plump by the next day, so it's easy to end up ordering it. But unfortunately, eating collagen doesn't instantly make your skin plump.

Collagen is a type of protein and is a component that makes up not only your skin but also blood vessels, ligaments, and cartilage. When you eat collagen, it gets broken down in the stomach and intestines, absorbed in the small intestine, and then transported to various parts of the body through the bloodstream. So even if you consume foods or supplements rich in collagen, it doesn't all get absorbed by your skin as-is.

If you're getting enough protein from your regular meals, you won't be lacking in collagen. Aim for around 65g of protein per day for adult men and 50g for adult women.

To prevent skin aging, basic care like sun protection and moisturizing is key. Also, although it's easy to get interested in cosmetics recommended by celebrities, everyone's skin is different. Observe your own skin carefully, do the care that feels good for you, and aim for healthy, beautiful skin.
