Should we beware of the sun?
Did you know?
We need the sun to be in a good mood! We also need the sun to stimulate our production of vitamin D, which is essential to stabilise bone mass. However, some of the sun’s rays can be too aggressive for the skin, particularly ultraviolet rays (UVA and UVB). Ultraviolet rays are believed to be the main cause of premature skin ageing.
- UVB rays allow us to tan, but they also cause sunburn.
- UVA rays penetrate the skin more deeply and are responsible for premature ageing of the skin.
The sun’s rays also cause the oxidation of the elastin and collagen fibres found in the dermis which ensure the skin’s youthful appearance.
Studies have shown that women who regularly wear a sunscreen to protect from UV rays have skin that appears to be on average 4 years younger than the skin of other women (Source: Ipsos Centres Santé de la peau Vichy). UVB and UVA rays can also cause allergies and pigmentary disorders.
Excessive exposure to sunlight is responsible for the appearance of wrinkles and also increases the risk of developing skin cancer even dozens of years later.
What to do on a daily basis:
You must protect your skin from UV rays all year long. UVB rays are stronger during the summer, but UVA rays are present all year round and are just as strong when the weather is cooler.
Beware of sun exposure when you’re in the mountains (skiing, hiking, etc.), because snow reflects UV rays three times more than sand and 6 to 8 times more than water.
A sunscreen that protects against ultraviolet radiation is essential to defend your skin from exposure to the sun. Choose a product that is appropriate for your phototype and for the climate where you live. Consult your pharmacist if you are unsure. Don’t forget to wear a hat and sunglasses since eyes are also exposed to the sun’s rays, which can damage the crystalline lens (opacity in the crystalline lens is known as a cataract).
