Sunscreen, because you have to use it always and in any case


We still make the mistake of being careless with applying sunscreen when we are away from the beach. Often, with the excuse of “today it is cloudy, the sun does not beat strongly”, or “I have to stay outside a little and for most of the time in the shade”, we do not give weight to the use of this product, which in reality should be chosen all year round to avoid the appearance of wrinkles, but above all skin diseases. Let’s see why you have to love this cream, not only when you are at the sea or the lake!

Sunscreen is often mistakenly seen as a product limited to the environment of beaches and possibly mountains. In fact, its use is always fundamental for the health of the skin, wherever you are (and in any season).

Ultraviolet rays hit the epidermis all year round (obviously, with more or less high intensity) and can cause hyper-pigmentation, wrinkles, or as is known, in the worst case even a tumor. We cannot therefore let our guard down and forget about good protection when we leave the house. Indeed, this product should be a must have of any self-respecting skincare routine. Just think that UV and UVB rays are at least reduced by the presence of clouds, while UVA rays are present and powerful all year round.

Sun protection: do you know the difference between UVA and UVB rays?

Because you must always apply sunscreen for UVA rays

THE UVA rays represent about 95% of UV rays, therefore their ray plays a constant action at all times of the day e both in summer and in winter. Their power means that they are able to pass the epidermis reaching the dermis.

These characteristics determine primarily an important factor in the incidence of skin cancers. But it also results in premature aging of the skin and the appearance of wrinkles.

UVB rays, lighter but not for this to be ignored

THE UVB rays instead constitute the 5% of UV rays and are present especially between April and October. Their intensity is strongly linked to factors such as the season, the time, the altitude and, as previously mentioned, the presence of clouds in the sky, which tend to shield the action of these rays.

UVB rays do not go beyond our dermis layer, stopping at the epidermis. However, they are responsible for activating the tan and can therefore determine the appearance of spots, rashes and burns. Very light and reflective surfaces, such as ice, water, snow, metals, sand or polystyrene, can double the intensity of UV radiation.
Precisely for this reason, sunscreen is not a habit, but a real necessity that makes us protected in every situation.

What is the SPF

SPF stands for “Solar Protection Factor”And indicates the level of protection of a sunscreen.

The numerical value of the SPF expresses the ratio between the MED (ie the number of necessary radiations that cause an erythema on skin protected by the sun filter) and the MED on unprotected skin.

A practical example: If it takes 20 minutes to determine redness without sunscreen, a sunscreen that has an SPF of 15 could prevent redness for 15 times longer. However, it is always advisable not to go below the 30 SPF protection, which is able to counteract irritation and redness. It is also advisable to choose a product with the wording “broad spectrum”, which means that it protects against both UVA and UVB rays.

Because you must always love sunscreen

Our skin is exposed to consequences of the sun’s rays all year round, not just when you choose to make sea lizards.

As we have seen before, the rays can be of two types, both of which are harmful to our body. UVBs cause sunburn and burns and are concentrated in the spring-summer period, although their intensity also depends on the presence of clouds and in general on the climate.

UVA rays are a year-round powerhouse and cause wrinkles, sun spots and skin diseases to appear.

THE damage not only concern sun burns, which are very annoying especially in some delicate points such as the mouth, but also the formation of premature wrinkles. Even more serious consequences can be actinic kerosia, that is, precancerous growths, or skin tumors.

Skin diseases resulting from incorrect sun exposure

Although it seems that melanoma affects areas of the body usually not exposed to sunlight, it must also be emphasized that the phototype is among the risk factors (for example light eyes, blond hair, very light skin). The tan is the only modifiable factor among those of risk mentioned, besides annoyances such as sun burns (especially in children), affect more on their skin because it “stores” the damage.

It should be noted that frequent exposure to UV rays in solarium increases the risk of skin cancer.

Photoaging, when the skin gets old prematurely

Prolonged and unprotected exposure to sunlight irreversibly causes premature aging of the skin, also known as photoaging. The sun causes the formation of wrinkles rather thick which represent an irregularity of the pigmentation. But not only that: it also results in the onset of large spots, similar to freckles, but with a yellowish color and rough consistency.

You must take into account that, although people with fair complexions are much more prone to the appearance of such discolorations, every type of epidermis is likely to be affected.
