There are a few basic causes for hyperpigmentation:
- Excess production of melanin, the pigment that gives skin the colour can cause hyperpigmentation- remove from here
- Excessive exposure to the sun can cause an increase in melanin production
- Certain medications, especially certain chemotherapy drugs can lead to hyperpigmentation
- When there is a change in the hormonal levels due to pregnancy or any other condition, there can be an increase in the melanin production
- Underlying medical conditions such as Addison’s disease tends to affect the adrenal glands, which in turn will affect the hormonal and melanin production
Methods of diagnosis
The main methods of diagnosis include:
- Wood’s Lamp: This is a device that emits UV light and is one of the most preferred methods of diagnosing hyperpigmentation. The procedure is performed in a dark room. This helps in the determination of the type and extent of the pigmentation.
- Magnifying lamp: When the skin is looked at, under the magnifying lamp, the extent of the hyperpigmentation will be easy to determine. In addition, the same tool will also allow for the diagnosis of other associated skin conditions too
- Skin biopsy: In situations, where the lamps are not proving to be effective enough to gauge the extent of the pigmentation, the dermatologist might have to resort to a skin biopsy. This method might be especially useful for diagnosing the associated skin disorder
Advantage of Pigmentation Treatment
After a few sessions, you will start to notice that the pigments have started to fade away and the natural colouring of your skin is starting to return. In addition, the treatment can reduce the spread of the pigmentation. The treatment will also include treating the root cause of the condition, which will deter further appearance of the pigment.
