In March, the amount of ultraviolet rays gradually increases. It is said that the number will increase rapidly in April, and by May it will reach the same level as midsummer. There is a strong impression that "UV rays are the enemy of beauty," but in recent years, the importance of being exposed to UV rays has been pointed out.
We once again spoke to doctor Tomoko Hashimoto about the effects of ultraviolet rays on us and what we can do about them. Let's take another look at how we deal with UV rays.

Let's review it again! What effect does ultraviolet rays have on the skin?

``There are two types of ultraviolet rays that reach the ground: UV-A waves and UV-B waves, and each has a different effect on the skin,'' says Dr. Hashimoto.

"UV-A reaches the dermis and gradually damages the skin, causing the skin to lose its elasticity and firmness, causing wrinkles and sagging. This is what is called 'photoaging.'"
UV-A accounts for approximately 90% of the ultraviolet light that reaches the earth's surface. Since the wavelength is long and can pass through clouds and glass, it can be affected even on cloudy days or inside the house.

"On the other hand, UV-B is what makes your skin red. It is also called leisure ultraviolet rays, and when exposed to it rapidly, it can cause inflammation on the skin, causing it to become red like a burn (sunburn) or turn black due to sunburn (suntan). Not only that, but it can also cause age spots and freckles.”

Dryness further accelerates aging.
"Repeated exposure to UV rays causes the skin to collect dead skin cells in an attempt to protect itself, causing it to become rough and dry. This reduces the effectiveness of skin care products by half, and the dryness progresses further, weakening the barrier function. This results in even more dryness. This is a vicious cycle that continues...”

Sunscreen is a must to protect your skin from these problems. The degree of UV-A prevention effect is "PA", and the more "+" there is, the higher the prevention effect. On the other hand, "SPF" indicates the effectiveness of UV-B protection, and the higher the numerical value, the higher the protection effect.
``It is said that the amount of ultraviolet rays has been increasing in recent years due to global warming.It is important to wear sunscreen not only in summer, but from early spring onwards, and even throughout the year if possible, even when you are indoors. It is important"

Vitamin D is produced by exposure to UV rays.

On the other hand, Professor Hashimoto says, ``Exposing yourself to ultraviolet rays is necessary for building a healthy body.''
"Vitamin D is produced when exposed to ultraviolet rays. Although it can be obtained through food, it is said that 60 to 70% of it is produced in the skin, and depending on the region and season, it is said that vitamin D is produced in the skin. It is necessary to sunbathe for about 30 minutes.

Vitamin D is a nutrient that works in various parts of the body.
"It is a component that helps calcium function and is very important for maintaining health. However, many people today tend to be deficient in vitamin D."
The reason for this is that many people avoid UV rays for beauty reasons, but it also seems to be due to lifestyle factors. Dr. Hashimoto points out that people who have many of the following items may be deficient in vitamin D.

I have few opportunities to go out and tend to stay indoors.
Spending a lot of time working and living indoors
Exercise indoors, such as at a gym
Opportunities to shop online have increased
Life centered on night owls, such as night shifts
Work location is directly connected to the station
When going out in the summer, cover your entire body with a parasol, hat, sunglasses, mask, long sleeves, gloves, etc.

People who don't spend much time in sunlight on a daily basis should be careful.

Learn how to deal with UV rays effectively

It's better not to be exposed to UV rays for your skin, but you need to be exposed to UV rays to maintain your health.
So how should we deal with UV rays?

``Recently, sunscreens that do not inhibit the production of vitamin D have begun to be released.It would be a good idea to try using such products.Even if you can't get them, you definitely want to avoid UV damage to your facial skin. , be sure to apply sunscreen to your face, and don't forget to take plenty of vitamins A and C, which have antioxidant effects, after exposure to UV rays.
Also, UV-B is the type of ultraviolet light involved in the production of vitamin D. In other words, one of the guidelines is to choose a sunscreen with a low SPF value and a high PA value.

"There must be some people who are really worried about skin damage or who work night shifts and can't get out during the day. For those people, supplement with vitamin D. We recommend taking 2,000 to 3,000 IU a day. To do"
With "Lypo-C Vitamin C+D", you can take in 1,000mg of vitamin C and 2,000IU of vitamin D in one package. Please use it for your daily health.

summary

It is important for beauty and health to know the bad and good points of ultraviolet rays and to deal with them effectively. However, as Dr. Hashimoto mentioned, many people tend to be deficient in vitamin D.
If you don't get much exposure to the sun or are concerned about your health, it is recommended that you check your blood vitamin D concentration at a clinic. Would you like to understand your current physical condition and think about future care?
