We have briefly explained about hyper pigmentation in our previous post. Hyper pigmentation is a skin condition which can cause mental distress as it affects the most visible parts of the body. Therefore, we thought of giving a detailed insight on hyperpigmentation and the causes behind it.
Hyper pigmentation is nothing but a change in skin color. It is mainly caused by over production of melanin on a particular area which changes the skin color and makes it darker compared to the remaining parts of the body. The reason for over production of melanin can be many and a few main causes are mentioned below.
Age spots, also called as dark spots appear on the frequently exposed parts of the body such as face, arms and feet. They generally appear after certain age because of the over exposure of body parts to sunlight.
Post Inflammation Hyperpigmentation
When a part of skin heals after an injury, skin trauma or acne, it causes post inflammation hyper pigmentation. This is mainly because of the stress undergone by the skin during the healing process. Certain skin treatments which includes extreme abrasion can also cause this skin condition
Melasma is a type of skin pigmentation caused by UV radiation. If a person’s sun sensitivity is high, they are prone to Melasma. The change in hormones during pregnancy is also one of the reasons behind Melasma. Sometimes intake of birth control pills can also cause this pigmentation.
Acanthosis Nigricans is caused by imbalanced hormones which are supposed to regulate the blood sugar levels. The pigmentation is caused around neck, underarms, knuckles and in some cases around the groin area. As the blood sugar regulating hormones are disturbed, acanthosis nigricans is also considered as a warning sign for diabetes.
Certain topical creams, especially the ones meant for skin lightening/fairness can also be the reason for hyper pigmentation. Even though they may show some results initially, the ingredients can react with the skin and with exposure to external factors such as sunlight can cause hyper pigmentation.
