Pigmentation or hyper pigmentation is a term that is used to describe the appearance of dark spots, patches or even general darkening of the skin. The upper layers of the skin contains cells call melanocytes which produce pigment called melanin. Human beings come in a spectacular spectrum of colours light, dark , freckled, auburn, blonde, brunette, grey or black hair. It’s amazing to think that this is due to a single type of pigment called melanin. The melanin is evenly distributed in our skin and gives us our skin colour . Other than to colour the skin (plus hair and eyes), the role of melanin is to protect the skin – it absorbs UVB radiation from the sun. A sun tan (melonogenesis) is the result of higher melanin production, the body’s own defences against that damaging UVB. Excessive skin pigmentation is a result of abnormal producti Hyperpigmentation, areas that are darker than the rest of the skin, result from excess melanin production and deposition. This discussion will only encompass pigmentation that is in the skin, and will not involve discussion of raised pigmented lesions, moles, or skin cancers. Hypopigmentation is the loss of skin pigmentation. This will not be discussed here. Excess skin pigmentation or hyper-pigmentation is usually caused by an overwhelming of the melanin-protective system. This leads to excess production and clumping of melanin, and the appearance of brown or darker spots of pigmentation in the skin. There are various causes of hyper-pigmentation both external and internal factors. The commonest external cause of is exposure to ultra violet radiation from the sun whereas the commonest internal cause is hormonal changes. The skin’s natural protection mechanism is to inject melanin or pigment like an umbrella over the cell nucleus, to try to prevent DNA damage. Unfortunately, too much UV oxidises the melanin, creating the freckles or dark spots, and will still damage skin cell DNA. Once the DNA has mutated, it will keep repeating this cell mutation. Pigmentation problems can be broken down as follows Treatment varies depending on the type of pigmentation problem and the individual’s skin. A full clinical assessment is performed at your initial consultation including an examination under the Woods Lamp ( UV light) which helps determine the severity and depth of pigmentation The more superficial the pigmentation the easier it responds to treatment: there is no perfect one treatment fixes all option ! Although pigmentation is a natural and unavoidable part of ageing, you can take steps to minimise its effects.
on and deposition of melanin by the melanocytes. Production of melanin is dependent on UV or sun exposure, and is a natural protective mechanism of the skin.
The first step towards clear skin, is simply contacting us for your initial consultation with one of our doctors, where we will discuss assess and discuss your needs and plan your pigmentation treatment.
