SUMMER – The sun hasn't quite set yet, but some are eagerly talking about their future tan. Exposing yourself to the sun to look “good” is a practice that is highly regarded by today's beauty standards. But unfortunately, the sun is much more dangerous than it seems to our skin.
As we explain to you in the video at the top of the articleTo fully understand why the sun is harmful to your health, you must first look at the effect of its rays on the skin.
Among those that reach us, there are three groups of aggressive rays. Infrared rays, which penetrate deep into the skin and are responsible for the sensation of heat. UVA (ultraviolet A), which reaches the dermis and accelerates skin aging. And ultraviolet B rays, which penetrate the skin and cause tanning and sunburn.
All of these rays damage the DNA in skin cells, which can cause burns, dark spots, and skin cancer. More than 80% of them are caused by excessive exposure to sunlight Public health France.
Sunscreen is not enough
The consequences of the sun on our skin can happen to all skin types, even with the use of sunscreen. Although its use is necessary, it is not applied in sufficient quantity and not frequently enough to properly protect the skin, even with a high index.
” In “real life”, you never add the required amount, so you have to divide your solar index by two for lower indices, or even by four for higher indices. “, explains dermatologist Christophe Bidani Health magazine. Therefore, a sunscreen with an index of 50 will have the effect of a sunscreen with an index of 25 when applied.
78% of French people believe that the sun is good for their health, according to A Study BVA According to the National Cancer Institute, which was implemented in 2022. The sun does have many benefits, but nothing justifies prolonged exposure.
It is said, for example, to help manufacture vitamin D, a vitamin that improves our immune system. It is true but there is no need to tan for hours, just a few minutes of exposure. In addition, it is possible to compensate by eating some foods rich in vitamin D, such as sardines, salmon, or eggs.
Prefer self-tanner
The only solution to get tanned skin this summer without harming your skin is self-tanning, according to dermatologists. These products contain dihydroxyacetone (DHA) or erythrulose, which are harmless substances that react with the top layer of skin to give it a temporary tanned appearance.
” Using a self-tanner is safer than lying in the sun or in a tanning booth “, explains Anjali Mahto, consultant dermatologist at the Cadogan Clinic in London, in an interview with worldwide.
If you really insist on sunbathing, cover up as much as possible, wear SPF 50 sunscreen, and take breaks in the shade very regularly. Your skin will thank you later.
