We need the sun to live, vitamin D is more than important for our body to function properly (I'm sure you've heard this more than once at this time of year, COVID), we must sunbathe but always with caution. The skin suffers with prolonged exposure, and that is why we must be aware of the importance of protecting ourselves from the sun every day.
Not only in summer.
The skin is continuously exposed, whether on cloudy days or sunny days, UVA rays act on our skin, so it is important to protect yourself from the sun at any time of the year.
What happens to our skin when we don't use sun protection? If you don't wear the correct sun protection, ultraviolet radiation can have terrible consequences on your skin. One of them can be photo-ageing, which causes wrinkles, expression lines on the forehead, eyes and mouth, dark spots and lack of tone and texture. In addition to sunburn, sun allergy, pigmentation disorders, acne... .....
In the long term, the sun can cause premature skin ageing and the two main types of skin cancer: basal cell carcinoma and melanoma. Hence the importance of protecting yourself from the sun all year round.
THE SHORT-TERM EFFECTS
UV/UVA rays have a series of harmful effects on the skin in the short term - yes, as you are reading, IN THE SHORT TERM! In the case of sunburn due to incorrect exposure, the sun's rays disrupt the chemical bonds in our DNA which leads to a break in the chain. When the cell detects DNA damage, "apoptosis" may occur or it may self-destruct.
This leads to an inflammatory process within the skin: blood vessels dilate, causing the skin to redden. They also become "leaky", which can cause fluid to leak into the skin, leading to swelling and blistering. Sunburn is classified as a first-degree burn and the main cause is UVB rays.
Sunburn is more than a source of intense discomfort: Just 5 blistering sunburns before the age of 20 can increase the risk of melanoma (skin cancer) by 80%.
Fortunately, the right sunscreen can significantly reduce the risk of sunburn and future skin cancer for you and your family.
Sunscreen contains sunscreens that absorb the energy of UV rays to prevent them from penetrating the skin and causing damage. Make sure your sunscreen contains high or very high UVB protection (check the SPF). At Clínica Dra. Paloma Ojale, we work with Heliocare sun protection, a range of medical cosmetics for skin care.
