¿Sabes la diferencia que hay entre los protectores solares?

Do you know the difference between sunscreens?

The first thing you should know is what you want to protect yourself from when you buy a sunscreen. Isn't it obvious? The sun, so I don't get sunburned! ... yeah, but it's better to dig a little deeper. The sun's energy reaches the earth in the form of visible light rays that we see, and in the form of infrared and ultraviolet (UV) rays that we don't see.

These UV rays can be divided into three categories: UVA, UVB and UVC, which vary in length.

UVA: Also known as ultraviolet rays, they have the least energy and represent 95% of ultraviolet radiation, reaching the dermis. When it reaches the deepest layers of the skin, it promotes aging.

UVB: although it is only 5% of the ultraviolet radiation that reaches the earth, it has considerably more energy than UVA rays. Compared to UVA rays, it reaches the most superficial layer of the skin, the epidermis, and is the one that activates your melanin and makes you burn.

UVC: These sun rays are the most harmless because they are stopped when they reach the ozone layer.

Within sunscreens there are different categories, but not all of them protect against all types of UV rays.

Here we leave you a guide with the differences, look carefully before buying a sunscreen in its category:

Broad spectrum sunscreen

Provides protection against both type A (UVA) and type B (UVB) ultraviolet rays. In general, most sunscreens protect us from UVB rays, preventing us from burning during the day, but not from UVA rays, and these are just as fearsome, although they do not have such a strong energy and also contribute to skin cancer and premature aging of the skin.

Only sunscreens that pass certain tests can be labeled as "broad spectrum". Therefore, if your current sunscreen is not labeled "broad spectrum", it is probably only protecting you from sunburn caused by UVB rays.

Sunscreen (not broad spectrum)

As we have already explained above, it only protects against UVB rays, but what SPF is recommended for it to be effective?

What many people don't know is that the higher the SPF score, the smaller the difference. This means that SPF 15 filters out about 93% of UVB rays while SPF 30 filters out about 97% and SPF 50 filters out about 98%.

Therefore, the WHO recommends at least SPF 30 sunscreen if you are going to be exposed to sunlight.

Protecting your skin from the sun is vital to be healthy, it is your armor, so try to get into the habit of using sunscreen daily, it is 5 minutes of your morning that can do more than any anti-wrinkle or treatment.
