Hyperpigmentation is the increase in melanin which causes the skin and nail to darken in colour. It occurs when excess melanin is deposited within the tissues. It is a very common and harmless skin disorder which leads to skin patches becoming darker than the normal surrounding area, resulting in uneven and abnormal skin tone. It can affect people of any race or colour. It is more of a cosmetic problem and may look unsightly causing a dent in your self-esteem and making you self conscious about your body image.
Causes of Hyperpigmentation:
- Inflammation of the Skin: Melanocytes are formed in the skin and is activated if there is long term exposure to the sun. Inflammation is commonly caused when the sunlight hits the skin cells. Melanocytes are permanently activated if the skin cells are continually exposed to solar rays over many years. It leads to the constant production of specialized melanocyte cells thus darkening certain areas of the skin.
- Other factors responsible for hyper-pigmentation: Other examples of external factors that may cause hyperpigmentation are:
- Inflammation of the skin caused by oral antibiotics and topical medicines to treat other skin diseases.
- poison ivy
- fabric dyes and
- chemotherapy drugs
- hormonal changes such as during pregnancy
