Your skin’s UV home solution is perfect! But is that all you need to do? Here are some UV damage by wavelength for your hair as well.
There are three types of UV rays and each wavelength causes different damage!
UV rays, which are usually represented as one group, are divided into three types according to their wavelengths: UV-A, UV-B, and UV-C.
First, UV-A affects deep into the skin, causing the skin to lose its elasticity due to the breakdown of collagen fibers, etc. This is what causes wrinkles and sagging. This causes wrinkles and sagging.
UV-A has a wavelength of 315 to 400 nanometers. It is not very toxic, but it slowly causes damage, so UV care is necessary not only for the skin but also for the scalp.
Note the highly toxic UV wavelengths, UV-B!
UV-B has a wavelength of 280-315 nanometers and produces UV damage on the surface of the skin. It is well known as a cause of blemishes.
Although it is nearly 1,000 times more toxic than UV-A, the amount of UV-B that reaches the ground is only about 10% of all UV rays. Because of its high toxicity, it is said to be a tricky wavelength to be aware of even in small amounts.
It is the UV-B that causes sunburn. Even the surface of the hair and scalp can produce UV damage, so the use of UV care products is recommended.
Three wavelengths you should be aware of to prevent UV damage
As we have introduced, ultraviolet radiation has different wavelengths, each of which has its own effects. Here are the three wavelengths of UV light in detail.
- UV-A has these characteristics at different wavelengths!
UV-A, which causes wrinkles and sagging, has a wavelength of 315-400 nanometers. Although it does not produce dramatic changes, skin damage can be serious if left unchecked over many years. The scalp is also exposed to UV-A and should be considered similarly damaged. In sunscreens, the number written as PA is for UV-A. - UV-B wavelengths have these characteristics!
UV-B, which causes spots and sunburn, has a wavelength of 280-315 nanometers. Although it reaches the ground only 10% of all UV rays, its toxicity is a concern. Proactive UV protection is necessary.
Since these wavelengths are also likely to affect hair and scalp, UV care should be taken carefully. In sunscreens, the number marked SPF is for UV-B protection.
- UV-C wavelengths have these characteristics!
UV-C has a wavelength of 100 to 280 nanometers. It is a very harmful UV wavelength and requires even more attention than UV-B. Until now, it was absorbed by the ozone layer, so it did not cause any physical harm. Today, the ozone layer is being depleted, so we must pay attention to future changes.
As I introduced, ultraviolet rays have different effects on different wavelengths. Let’s grasp the characteristics and implement measures to protect skin and hair from ultraviolet rays.
