Should you use sunscreen indoors?

Usage sunscreen has changed a lot in recent years. Previously, it was only used in the summer to go to the beach. It didn’t matter whether the person spent hours outdoors in the bright sun. They forgot that our star can burn far from sea level. Over time we become more aware of this aspect. We later realized the importance of using it on the face to prevent more than just cancer. Also from signs of aging. They even started using it all year round and reapplying it every two hours. Now, as if all this wasn’t enough, we’re seeing some influencers claim that they also use it when they’re indoors. Is this getting out of hand or is it really necessary?

Well, although it may seem strange, it is true. More and more research confirms the need to use sunscreen when we don’t meet outdoors. Usually there are three reasons, although one of them does not have sufficient scientific evidence.

The first reason is that usually We don’t spend 24 hours indoors. We usually go in and out, so if we apply sunscreen while we’re still at home, we won’t forget about it when we go outside. It’s about creating a routine that allows you to automatically protect yourself. The second reason is that some of the harmful radiation may pass through window glass. We better be protected. Finally, the last reason is blue screens of electronic devices. There is practically no scientific evidence for the latter, but the other two must be taken into account.

Anti-aging sunscreen

There are three types of ultraviolet radiation: UVA, UVB and UVC. Type C is the most energetic and can cause the most damage to our skin. Fortunately, they are completely absorbed by the ozone layer, so unless the famous hole in the ozone layer gets very large, we will be safe from them.

The following types are classified as type B. Some of them absorbed by the ozone layer but the other part reaches us. They are primarily responsible for burns and skin cancer because they can cause mutations in cells that cannot always be eliminated with treatment. natural recovery mechanisms.

Finally, the ozone layer does not absorb UVA. The upside is that they are the least harmful, but they interfere with skin aging. Therefore, the ideal solution when using a sunscreen is that it is effective against both UVA and UVB radiation.

The problem of interiors.

Window glass completely blocks UVB radiation. This way we are protected from skin cancer. However, UVA can pass through them. This is why it is recommended to use sunscreen on the face mainly when we are indoors.

For example, if we work in front of a window that gets a lot of sun, it can gradually contribute to skin aging. Ideally, it would be used all over the body, but it is especially recommended on the face to prevent the appearance of wrinkles.

In short, sunscreen isn’t as necessary indoors as it is outdoors, and that makes sense. But just in case, it doesn’t hurt to wear a face covering with an SPF of at least 30.
