Did you know that there are “UVA” and “UVB” in the ultraviolet rays that cause skin troubles? In particular, UVA occupies most of the ultraviolet rays that fall on the ground, so intensive care is required. Here, we will introduce in detail the difference between UVA and UVB, the effect on the skin, and the method of UV protection.
What is the difference between UVA and UVB?
Ultraviolet rays include UVA, UVB, and UVC. Of these, UVA and UVB have an adverse effect on the skin when they fall on the ground. Let’s take a closer look at the characteristics of UVA and UVB and their effects on the skin.
What is UVA
UVA is ultraviolet light that has a long wavelength and reaches deep into the skin. Although it does not cause sudden damage to the skin, it affects elasticity and firmness by reaching deep into the skin. In addition, it stimulates the production of melanin pigments, causing a type of “sunburn” that darkens the skin.
What is UVB
UVB is an ultraviolet ray that has a short wavelength and causes rapid damage to shallow areas of the skin. It causes inflammation due to sunburn (sunburn) and deposition of melanin pigment (suntan). It also causes spots and freckles by increasing the production of melanin pigments.
UVA needs special attention! ??
Both UVA and UVB measures are required to maintain healthy skin. Without proper measures, the effects of UV rays on the skin cannot be suppressed. Since UVA has the following characteristics, it is necessary to devise countermeasures.
Go through the window glass
UVA passes through the window glass and falls indoors and into the office. Therefore, I am not relieved because I am in my house or car. If you neglect to take measures against UV rays just because you can’t get out of your house or car, you will be damaged by UV rays.
Accumulated daily
UVA has the property of accumulating on the skin. Therefore, the more days you do not take measures against UV rays, the less elastic your skin will be. For example, even if you take measures against UV rays from spring to summer when the amount of UV rays is high, if you neglect to take measures from autumn to winter, UVA damage will accumulate on your skin and your skin will sag at an early stage. If you want to reduce the effects of UV rays as much as possible, it is important to take measures against UV rays every day.
What happens if I continue to be exposed to UVA? Watch out for photoaging
If you continue to be exposed to UVA, the following troubles will occur due to a phenomenon called photoaging.
Lose elasticity
The skin consists of “epidermis”, “dermis”, and “subcutaneous tissue” in order from the outside. UVA destroys collagen and elastin, which are present in the dermis and maintain the elasticity of the skin. As a result, the elasticity of the skin is lost and it becomes easier to give the impression of aging.
Spots become noticeable
When UVA falls on the skin, melanocytes produce melanin pigments. If you continue to be exposed to a large amount of UVA, that much melanin pigment will be produced and eventually deposited on your skin. As the melanin pigment continues to accumulate on the skin for many years, it turns into dark spots.
Sagging occurs
When UVA destroys collagen and elastin in the dermis, the skin loses its elasticity. As a result, the skin sags due to gravity. In addition, the sagging skin causes the skin to wrinkle. If you have a lot of sagging and wrinkles with respect to your age, you will look older than you really are.
What are the seasons and weather when there are many UVAs?
Many people think that ultraviolet rays are only shining on sunny days in summer. Let’s take a closer look at the seasons and weather when UVA is heavy.
May peaks
UVA begins to increase around March and is said to be the highest in May. UV rays will start to increase in early spring, so be careful not to make a mistake when you start taking measures against UV rays.
Be careful on cloudy days
UVA also falls on the ground even on cloudy days. Although it is relatively small, about 60% compared to a sunny day, it is sufficient to affect the skin. To prevent UVA damage from accumulating on your skin, take thorough measures against UV rays on cloudy or rainy days.
What should I do for UVA measures?
Then, what kind of measures can UVA be prevented? It is important to protect the skin while reducing the amount of UVA that falls on the skin. Prevent damage to your skin caused by UVA with the following measures.
Apply sunscreen even when you’re at home
UVA passes through the windows and enters the house, so it’s important to apply sunscreen even on days when you’re not out. If you don’t want to apply sunscreen when you’re at home, use a UV-blocking foundation or makeup base.
In addition, UVA also falls inside the car, so it is recommended to attach an arm cover to the arm that is easily exposed to UV rays.
Use UV-cut basic cosmetics
When you go out, don’t just apply sunscreen, but use foundations and basic cosmetics that have a UV-blocking effect. It is important to thoroughly prevent UVA from entering the skin.
Put a UV cut sticker on the window
By reducing the amount of UVA that falls on the skin, the effects on the skin can be further reduced. Put a sticker that has a UV blocking effect on the window. However, please note that the UV cut rate differs depending on the product. Choose a type of UV cut sticker that has a UV cut rate of 99% or more and does not change the color of the window.
Install UV-cut curtains
It is also effective to attach a curtain that has a UV blocking effect. Most of them have a UV cut rate of about 80 to 90%, and they block UVA sufficiently. If you want to block UVA more thoroughly, put a UV cut sticker on the window and attach a UV curtain.
However, depending on the type of UV curtain, the light blocking effect is very high, and the inside of the room becomes a dark atmosphere. If you want to avoid darkening the room, choose a curtain that has a high UV protection rate and is easy to take in light.
summary
UVA causes sagging skin by destroying collagen and elastin in the dermis. In addition, the risk of melanin pigments depositing on the skin and causing blemishes increases, so it is important to start countermeasures today. Thoroughly prevent UVA by using basic cosmetics that have a UV blocking effect, sunscreen cream, UV blocking stickers, and UV blocking curtains.
