We have waited so long for the English sun that we can often overdo it when it finally appears!
Although we are aware of the dangers associated with too much sun, how many of us actually know what happens to our skin when it burns?
The redness, swelling, and pain of sunburn are actually the symptoms of a response to the sun's UV rays.
The intense energy of UV radiation damages molecules on the skin surface and triggers the synthesis of proteins such as prostaglandins and cytokines .
These proteins in turn cause the blood vessels to expand and inflammatory cells to accumulate in the affected area – then you will feel the burning sensation!
Usually, it takes 4-6 hours for these proteins to appear after the initial UV overexposure. Therefore, sunburn can occur long after exposure.
Although the strange sunburn can be treated, the real danger is prolonged or regular overexposure to UV radiation.
In these cases, skin cells become so damaged that the body can no longer repair them, and they irreversibly mutate into potentially cancerous cells.
The other, less serious, but unfortunately more effective deterrent to sunbathing is the very real aging effect of UV radiation.
Amazingly, sun damage accounts for 90% of premature skin aging !
Although scientists are not entirely sure how this process works, some believe that this is due to the ability of UV rays to break down collagen.
Collagen naturally decreases with age and is the substance that is responsible for maintaining skin firmness, firmness and elasticity. The less collagen, the more relaxed, lined and dull skin appears.
Regular readers of the blog will know that Pai has not yet found a fully effective natural sun protection factor (and in particular stays away from those that contain methyl paraben).
As always, our best advice for protecting the skin is to stay away from the sun during peak hours from 11:00 p.m. to 3:00 p.m. or when you are out to hide. A wide brimmed hat is a girl's best friend!
It is also important to ensure that your diet and skin care are high in antioxidants, as this promotes long-term skin health.
