Re: Melanin - Pigment
Melanin is created by Melanin cells deep within the Skin's Epidermis. What causes this discolouration (often referred to as sun spot or age spots) is Sun Damage. When you over-expose your skin to the Sun's rays, you damage your Melanin cells (one of the many forms of sun damage). The damaged Melanin cell then goes into over-time produce large amounts of Melanin, which in turn reaches the surface of the epidermis, which is the discolouration you are talking about. It gets worse in the Summer because the Melanin Cells are already damaged and super-sensitive, so any un-protected exposure to the sun is going to cause further damage, therefore, more large amounts of Melanin.
As for a cure, I know of none. But I do know that Clinique has a product called Advanced Stop Signs, which sends signals to the over-active Melanin cells and tells them to chill out, which with continued use, the discolourations WILL fade. There is a catch though, as I said b/4, this is not a cure. The minute you stop using the product, the cells will go back to being over-active, and you must wear a sunscreen with it. I hope I've helped you to at least understand.
