Causes of Skin Pigmentation
The sun emits UV rays that are invisible to the naked eye. There are three kinds of UV rays: UVA, UVB and UVC rays. UVC rays have very short wavelengths and are absorbed by the earth’s ozone layer, preventing them from reaching the earth’s surface. So that’s one kind of UV ray we needn’t worry about. UVA and UVB rays, however, penetrate the atmosphere and play an important role in premature skin ageing, eye damage and skin cancer. They also suppress the body’s immune system, reducing its ability to fight diseases.
UVB rays penetrate the skin’s surface, activating cells called melanocytes. These cells produce a pigment called melanin that rises to the skin’s surface and appears as a tan. UVB rays can cause sunburn and, in extreme cases, even skin cancer.
UVA rays are the most dangerous. They penetrate the skin’s deepest layers and cause deep-skin damage. While a tan will eventually fade away, UVA rays continue to damage your skin from deep within. This is what eventually causes age spots, pigmentation and fine lines to appear.
Pigmentation can also be the result of genetics, stress and fluctuating hormones. Birth control pills and menopause can cause unusual fluctuations in hormone levels, causing pigmentation of the skin. Insulin resistance, overly aggressive skin care treatment and even use of certain hair dyes can cause discoloration of the skin.
Exposure to an unhealthy environment with pollution and toxins also cause damage to the skin, impairing cell structure and making the skin look dull and dry. Another common cause could be your method of hair removal; creams, tweezers and waxing can inflame the skin, causing PIH, or post-inflammatory hyperpigmentation.
