Pigmentation Treatment in Cambridge.

What is Pigmentation?

Pigmentation in the skin results from cells (melanocytes) at the base of the top layer of skin, releasing granules of pigment (melanosomes) into this upper layer.  The colour of our skin is determined by how much melanin is contained in the melanosomes.

Normally this is well controlled by our body.  Exposure to UV light can excite the melanocytes and cause them to release more melanin to produce a sun tan.  Once the exposure is stopped the tanning process ceases and over the following weeks the tan fades as these outer layers of skin cells are shed.

We tend to see changes in pigmentation as a problem when it appears uneven, indicates ageing or signifies a lower social status.

The causes of pigmentation change...

Sun Damage

Pigmentation changes can either be a darkening of the skin – hyperpigmentation or a lightening of the skin hypopigmentation. By far the most common cause of pigmentation change is exposure to UV light in sunlight. every time we get a sun tan we are causing long term damage to our skin. Healthy young looking skin can cover the damage done but as we age the underlying damage becomes more apparent.

The adjacent images compare the visible light image of a young woman with an ultraviolet light image of what is under the surface.

note: The green colour is computer generated and this level of underlying damage is very common.

When this damage accumulates it will typically produce age spots, skin laxity and damage to the skin’s DNA. The melanocytes can also be damaged if there has been extreme exposure.  This will appear as light spots of hypopigmentation.

Probably the worst outcome is a malignant skin tumor. These tend to appear as moles that change in shape and or colour. If there is any doubt regardiing the status of a mole you need to urgently have it checked. Ignoring it could prove fatal.


Clinical trials conducted in Germany and China have shown that pollution, especially that consisting of particles less than 2.5um in size does not rest on the surface of the skin. Instead it is able to penetrate the skin to the level of the melanocytes where it can agitate them to release more melanin resulting in premature age spots and damage the DNA of the skin cells resulting in a loss of collagen and premature ageing of the skin. One of the main conclusions was that people living in cities typically appear to age 10% faster than their country cousins.

Post Inflammatory Hyperpigmentation

Any event that causes inflammation of the skin can result in hyperpigmentation. The potential causes include but are not limited to, acne scarring, other forms of injury, skin treatments, especially strong acid peels and energy based treatments. Darker skins tend to more easily pigment and special care needs to be taken when treating darker skin types.


A condition that primarily affects women It appears as a darkened patch of skin that is persistent and even after treatment will have a tendency to return. It is also different from other types of pigmentation such as age spots in that it can exist in both the superficial epidermal and deeper dermal layers of the skin. The causes of melasma are not fully understood but factors which tend to promote melasma include exposure to ultraviolet light, hormonal changes especially during and post pregnancy, genetic predisposition and inflammation. The result of these “triggers” is an increase in melanin production in localised areas of the skin resulting in dark patches. Women with darker skin types are far more prone to developing melasma.
