Hello! My name is Kigawa, and I work for Bi Natural and Milobina.

Last time, I wrote about how I was told that my bone density was comparable to that of a teenage boy, and the person who had my bone density measured at that time was a Morinaga Milk home delivery campaign.

In the end, the discussion changed from calcium to bifidobacteria, and I learned a lot, and he also mentioned that there is a close relationship between the condition of the large intestine and the degree of dryness of the skin. Yeah, I understood that too.

I briefly mentioned this in a recent blog post, but hearing stories like this makes me realize how a healthy body has a beautiful skin, and even has a positive effect on the moisture of the skin. , I hope you can understand it somehow.

Today, I would like to write about what I have noticed so far about dry skin, and what I think is true.

There is so much information out there about skin, but it is often the case that the information written is the exact opposite depending on the writer's personality, position, company, etc.

I'm the type of person who first questions what's written. That's what I'm saying, but if you do it that way, it won't turn out that way. What about that? Like...

Especially when it comes to what cosmetic manufacturers are saying, whoa! There are times when I think that makes sense, but there are also times when I feel like, "Huh?".

Therefore, I will only write about what I have understood through my experiences so far.

When it comes to dry skin, there are several causes. But before we look into the cause, I would like to explain what dry skin is causing us.

I would be happy if there was even one thing that made you think, "Huh? Is this also an effect of dryness?"

Well, stains are a problem for most people of yellow color.

By the way, melanin acts as a shade that protects the body from irritation. In other words, when the skin receives strong stimulation from ultraviolet rays, it is protected by covering it with a black curtain so that the ultraviolet rays do not reach any deeper. (There are other functions as well, but I will return to them somewhere)

Stimulation is not just ultraviolet rays; all types of stimulation promote the secretion of melanin.

* Towel to wipe your face after washing your face
* Temperature of hot water and irritation of cotton when washing your face
* Strong flapping putting, rubbing stimulation, etc.

It is very important to be careful on a regular basis.

Melanin is produced by cells called melanocytes, which normally hide in the basal layer (skin cell production factory), but when they sense a stimulus, they extend many tentacles into the spaces between cells and release melanin from their tips. Spit it out and inject the melanin into each cell one by one.

I mentioned earlier that yellow people have the same number of melanocytes in both black and white people.

So the difference is the ability to produce melanin.

Yellow people and black people have an excellent ability to produce melanin, so they can produce more melanin even with the slightest stimulus, which protects their skin, but on the other hand, they are more likely to get dark spots.

Black people don't stand out because they are all black, but this is not the case with yellow people.

And speaking of white people...Milobina's vice president is a white Australian. Even when I'm in Japan or Australia, I walk around without much sunscreen, so my face and neck often get red from around May, and I think to myself, ``Wow, this is the season where UV rays are strong.''

Despite being almost the same age as me (50 years old), he doesn't have any spots on his face...unfortunately, I do!

This is because white people produce less melanin. Older Caucasians come from colder regions, so they don't need as much melanin production ability. On the other hand, it is also said that this is because the skin does not produce melanin in order to absorb sunlight so that its health is not affected by lack of sunlight.

As usual, the topic has gone off topic again, but there are things other than sunscreen that protect us from UV rays and external stimuli.

That's what moisturizes your skin.

Moisture in the skin refers to the moisture in the stratum corneum, and if the stratum corneum has sufficient moisture, compared to dry skin, our skin will be more susceptible to damage even when exposed to the same ultraviolet rays. It's difficult.

When people with dry skin and those with well-hydrated skin walk during the day in the Australian summer, not only the amount of melanin produced, but also the damage to their skin, are completely different.

Ultraviolet rays are highly irritating, but one thing that is surprisingly little known is that they have the power to cause intense drying.

For example, when you dry your laundry in the shade with good ventilation, there is a huge difference in the drying speed when you dry it in the sun, right? When I end up doing laundry too late, I try my best to hang it out in the sun (lol).

However, with this, the dryness has completely changed, so I'm really desperate!

This means that when exposed to UV rays, your skin becomes extremely dry, making it easier for UV rays to penetrate deep into your skin.

And that can cause stains and sagging...

Suppose you have dry skin. If I were to spend the Australian summer in that state... just thinking about it would be terrifying...(*´Д｀)

Australian sunscreens are all sticky compared to Japanese ones, but I think that's probably because they are aware of this fact.

Oh, and Milobina too.Sunscreen with a moisturizing effectThere is, so please try using it if you like. It's also great that you can wash it off with soap.

Moisturizing your skin is even more important than sunscreen when it comes to UV protection.

In addition to water, please try to keep your skin moisturized by using oils and creams instead of just getting a little sticky.

So, even though it's winter now, I ended up talking about how dry skin actually causes damage from ultraviolet rays, causing age spots and sagging skin.

As you may have heard, sagging occurs when the part of the skin below the basal layer called the dermis is damaged.

The layer above the basal layer is called the epidermis, and is reborn every 28 days (though the older you get, the slower this cycle becomes), so it's a bit safe, but once the dermis layer is damaged, it is difficult to regenerate.

You may have heard of collagen fibers, and they play the role of springs. Sagging occurs when the spring is no longer effective...

Well, it looks like it's going to be long, so I'll continue next time!

I would like to talk about dry skin.

Thank you for reading to the end today!

see you.
