Everything you need to know about UV rays and premature skin aging!

What are UV rays? Why do you have to protect yourself against both UVA and UVB rays? And gives SPF protection against?
Most people know that one should protect themselves from the sun’s UV rays and that UV rays are harmful because it causes mole and other skin cancers. Some also know that UV rays along with air pollution are the two main causes of premature aging of the skin.
But what exactly are UV rays? How do they affect the skin? Why are they harmful to us? And what is the solar factor? And where which solar factor should you use?We have gathered all the information you need in two articles, one about UVA and UVB rays (including) and one about solar factor and SPF .

UV rays are energy

UV rays are energy that moves like waves from the sun to the earth. It can in many ways be compared to waves moving on the sea. There is also energy that moves as waves. We call these energy waves electromagnetic rays. There are many types of electromagnetic radiation, and the difference between them is the wavelength. That is, the distance between each wave peak. Directly linked to the wavelength is also the energy level.

Radio waves, microwaves, infrared radiation, visible light, UV rays, X-rays and gamma rays are thus the same types of energy waves, but with different wavelength and energy content. The human eye can only see the visible light, which has all the colors of the rainbow. Red has the longest wavelength. The violet has the shortest wavelength (but the highest energy).

UV rays stand for ultraviolet radiation. It is because it resembles the color violet, but it has just slightly shorter wavelength than violet, and is just outside the wavelength the human eye can see. We cannot therefore see UV rays. But even if we do not see the energy, it can certainly affect us. On the other side of the visible light we have infrared radiation. Infrared radiation has just a little longer wavelength than the color red, so we just can’t see it.

How can UV rays be so dangerous when it has so many similarities with visible light?

This is because there are some structures in the skin that have such a shape, size and location in the skin layer that fits with the wavelength of the UV rays. These structures are therefore hit by the UV rays and absorb the energy from them. Unfortunately, several of the structures are very vulnerable and change when hit by UV rays.

UVB rays have shorter wavelength and more energy than UVA rays. The UVB rays mainly penetrate the epidermis only and are absorbed into structures there. While UVA rays to some extent affect the epidermis, but largely go through this and down into the dermis (dermis).

How does UVB rays affect the epidermis?

I am the epidermis man has pigment cells that produce pigment (melanin) that gives color to moles and the tan one gets from sun exposure. That is why I develop mucosal mumps and other skin cancers. It is also her husband being sunburned, which in itself is the pigment cells about the signal to produce more pigment. Pigment is one of the structures that absorb UV rays without it causing significant damage to the skin. Pigment is therefore the skin’s own protection against UV rays. The protection does not come completely free because it causes oxidative stress that eats away from the skin’s antioxidant layer. The most problematic of UVB rays on the unfortunately is to a large extent hit the DNA I cells. DNA is the cell’s genetic material and recipe for how to behave. The energy from the radiation can cause DNA mutations damage and make the cell behave differently. Some of the DNA damage can be repaired in whole or in part, while other times the damage is so great on the cell rather I choose to go programmed cell death. When the damage is not repaired, the cells surviving this can give cells that can eventually develop into cancer cells.

Niacinamide, which is my high concentration, I am anchor star SUPERMAT and I URBAN PROTECTION, is among the active substances known with good documentation on improving the repair of DNA damage caused by UV radiation. I additionally counteract Niacinamide on the UV radiation weakens the immune system I skin. Some research suggests that impaired immune system skin increases skin cancer risk.

In summary: UVB rays mainly affect the epidermis and cause sunburn, hyperpigmentation, pigmentation and skin cancer.

Did you know?

  • UVA rays cause premature skin aging.

  • UVB rays cause sunburn, skin cancer, and pigment damage, but are less important than UVA rays compared to premature skin aging.

  • SPF only says something about protection against UVB rays.

  • SPF30 filters 97% of the UVB rays while SPF50 filters 98%. Other factors such as uneven application and sweating usually have more to say than using SPF30 or SPF50.

  • The side windows in cars filter out almost 100% of the UVB rays, but only approx. 20% of the UVA rays. It is therefore important to protect yourself from UVA rays in the car too, to avoid premature aging of the skin!

How does UVA affect the leather skin?

UVA rays affect the epidermis to some extent, but go deep into the dermis and affect it. UVA rays have a wavelength that does not hit DNA directly as UVB does. Instead, it strikes structures that cause oxidative stress. Oxidative stress is a chemical chain reaction that changes and affects skin structures. Oxidative stress can cause DNA damage and cancer. In addition, oxidative stress is what most causes premature aging of the skin.

This is because oxidative stress starts processes in the skin where the collagen fiber structure and the elastic fibers in the skin break down. The collagen fiber network and the elastic fibers are what gives the skin strength and elasticity. Oxidative stress also causes micro-inflammation of the skin through activation of inflammatory signaling pathways. The body’s defense against oxidative stress is antioxidants. Unfortunately, UV rays quickly use up the skin’s own antioxidant layer. Dr. Ankerstärn has high antioxidant products. In URBAN PROTECTION we have several potent antioxidants to counteract oxidative stress and premature aging of the skin.

In summary: UVB rays mainly affect the epidermis and cause sunburn, hyperpigmentation, pigmentation and skin cancer.

UV protection in day cream is very important

UV protection consists of UV filters which can be divided into physical and chemical filters. Physical filters act as mirrors and reflect UV rays away from the skin. As mentioned earlier, visible light and UV rays are similar. Therefore, visible light will also be reflected away by physical filters. This is why these are often very shiny and shiny on the skin. Physical filters are like a film on the skin. Chemical filters penetrate the skin slightly and absorb the UV rays so that they do not damage the skin. Some people think chemical filters sound dangerous because of the word chemical. Both physical and chemical filters are chemical structures. Chemical filters are called chemical because the chemical reaction takes place in the filter instead of in the skin by UV exposure.

URBAN PROTECTION daycream has both high solar factor (SPF30) and UVA protection – broad spectrum UV protection ! This means good protection against both UVB and UVA rays. Are you wondering what the difference between SPF30 and SPF50 is? Read more here!

Did you know that UVA filters in day cream are also important when driving a car?

Few people know that many side views in cars filter out only 20% of UVA rays, while almost all UVB radiation is stopped. Therefore, you do not get sunburned in the car, but you can certainly get UV damage and premature aging of the skin in the car. Some professional drivers have more UV damage to the skin on the left side of the face and arm than the right. UVA protection in day cream is therefore very important!
