WHAT CAUSES PIGMENTATION?
When it comes to hyperpigmentation, there is an excess production of melanin that causes patches of skin to darken. This results in those pesky brown sunspots and post acne dark marks that remain even after the skin has healed. And then there’s melasma, a hormonal form of pigmentation that is a consequence of pregnancy, contraception and fertility treatment. Melasma usually surfaces on the forehead and upper lip.
If you notice your freckles become darker after being outdoors, that’s a result of melanin production stimulated by UV rays. The sun is not always our friend – especially when it comes to pigmentation. To further complicate, pigmentation is not always instant. On a rather shocking note, sun damage can take ten years to reveal itself! While sun exposure is the main cause of skin discolouration, we cannot exclude pollution, genetics and hormones.
