The solar filter inside the house?


We responds

A few days ago we talked about the possible vitamin D deficiency that your body can suffer while you are out of the sun and we recommended taking it with the window open for a few minutes each day.

We did not say at the time that, although to fix the vitamin D it is necessary to open the window, that does not mean that the glass does not filter rays.

In fact, it lets them pass. At least, if not all, a high percentage of them. Specifically, ultraviolet rays A.

Work glued to a window

Unlike UVB, which is responsible for sunburn, the sun’s UVA rays tan, reach deep levels in the dermis, and can deteriorate collagen and elastin. They are the big culprits of pigment spots on the skin. In general, from photoaging. Ultimately, if there is cell damage, from skin cancer.

When you put on cream with sun protection, even if you are not going to go out, make sure it is broad-spectrum, that is, it protects from UVB and UVA rays. It is known because on the bottle there is a stamp in the shape of a circle with the word UVA inside.

Reapply the filter

“For everyday use, when we go to the office, it is advisable to apply sunscreen after facial care treatment and before makeup. In this case – and as long as we are not a particularly sensitive phototype and we are not going to be in direct exposure to the sun throughout the day – reapplication would not be necessary ”, says Ana Gallego, pharmacist, and creator of Sileä.

The problem comes if you are all day in front of a window through which the sun enters (lucky you).

Sunscreens lose effectiveness after three hours or after sweating or bathing, so if you’re going to be in front of a window all day, don’t forget to reapply the cream. If you want, there are some products that can be used on top of makeup and are perfect for these reapplications.

Blue light

Although there is no consensus in the scientific community on how to protect against it, many dermatologists are already talking about the need to protect against visible light (blue light) that screens emit.

Given the number of hours we spend exposed to them, it should be taken into account.

In confinement, even if we do not go out on the street and, therefore, we do not expose ourselves so much to the ultraviolet and infrared light than the sun emits, we spend more hours at home, many times in front of a screen: working, consulting the news in networks social, watching television, even exercising following a table on YouTube, or watching our friends or family through Zoom or Teams.

Heliocare warns us: If on average we spent almost 11 hours a day in front of screens that emit blue light, with the quarantine this figure has increased. Records have been broken in television consumption and also in Internet use.

Blue light affects eye health and causes mental exhaustion.

“In addition, this artificial blue light, emitted by digital devices, penetrates to the deepest layers of the skin, causing skin cell damage and accelerating photoaging of the skin. The only way to combat these harmful effects is to deal with this radiation using a broad-spectrum sunscreen daily ”, the Spanish firm recommends.

Those who do not agree with the theory of protecting with sunscreens for use, recommend, of course, giving the skin antioxidants in serums and creams for daily use. Vitamin C, resveratrol, and ferulic acid are the gold standard for antioxidant ingredients.
