Pigmentation of skin is a problem which is usually triggered by overexposure to the sun. So when you go tanning your skin in the sun, you could end up with a blotchy looking skin due to skin pigmentation. Our skin has tiny pigment producing cells, which are responsible for the kind of skin complexion that we have, and when these cells are subjected to extreme sunlight, they panic and their basic nature changes. The outcome could be that they go on producing extra melanoma on a permanent basis, which will mean darkening of the skin on a permanent basis.
If you’ve been dying to get a permanent tan on your skin, this theory will definitely make you a bit excited; however there is a downside to it. The main problem which prevents you from enjoying a uniform tan across your skin is that not all of the pigment producing cells may react in the same manner to the sun exposure. So while some of the cells may produce a lot of extra melanin, there will be other cells which will not react in the same manner and obviously your skin will look blotchy.
Also with over exposure to sun rays, some of these pigmentation cells may shut down working permanently, being unable to bear the stress. And the result of this is that, the area surrounding the cell turns white on a permanent basis and can never be tanned. These white patches are quite sordid to look at and this particular skin condition is called hypo-pigmentation. And what makes this scenario even more solemn is that these white patches are overly predisposed to turning into skin cancer cells.
To prevent pigmentation problem, the obvious solution lies in protecting your body skin from the harsh rays of the sun. So when you’re stepping out in the sun, don’t forget to carry your sun umbrella, and wear clothes which cover the maximum of your body skin. And for all body areas which cannot be concealed in the clothing and are likely to suffer sun damage, make liberal use of a strong sunscreen lotion.
