The chief cause of skin reddening and sunburn
We have all been guilty of soaking up the sun’s rays.
And most of us, can put our hand up to being sunburnt at some point in our lives.
But what exactly is sunburn?
Well the reason your skin gets burnt is due to UVB rays.
Why? Because they literally cook your cells from the inside out.
It alters the molecular structure of your once healthy cells, turning them into big pink mutations, predisposing them to cancerous cells.
Sorry to be quite so explicit.
But in reality this is sunburn and just like the damaging effects of UVA, to much exposure is frightening.
DAMAGING UVB RAYS
UVB is the middle range of ultra violet light, its wave lengths are 200-290nm in length.
It is not dubbed the burning ray for nothing.
When you lay in the sun and watch your skin become inflamed, what is happening is that rogue molecules referred to as free radicals are being created.
The sun is stressful on the skin, causing it to produce more and more free radicals.
As UVB penetrates it directly attacks your DNA, injuring healthy cells and fibroblasts, which produce the skins collagen and elastin, our internal scaffolding.
Defense cells rush in to try to undo any harm; unfortunately the result is never quite like new.
When elastin decreases, our skin starts to lose its flexibility and becomes loose and less resilient, when collagen breaks down, our skin cells becomes disorganised and abnormal.
This article does a great job, of describing what happens to the aging face.
DOES AFTER SUN LOTION OFFER RELIEF
Have you ever stayed in the sun way to long, and as soon as you get home literally poured on after sun lotion, in a bid to diffuse inflammation?
Well in reality what is happening, is that as long as you skin is red and hot, those excitable rogue molecules I was talking about earlier, the free radicals, are continuing with their cycle of destruction on the skin.
That’s right, the skin’s stress response system signals are still on red alert, so you’re AFTER SUN LOTION is only offering only TEMPORARY RELIEF and WON’T REVERSE DAMAGE done by those BURNING rays.
Sorry to be the bearer of bad news, but the skin just keeps on burning.
UVB AND DARK PATCHES ON THE SKIN
Now if that is not enough, when the body is exposed to ultra violet light in the form of UVB rays, the production of melanin pigment is increased.
In this article I discuss melanin and how it acts like our skin’s tiny umbrella, your very own inbuilt UV filter.
But when the UVB rays attack the melanocyte cells, this makes them unable to spread pigment evenly, which is why sunburnt skin, is often characterised by dark uneven patches, known as hyperpigmentation.
