What is Pigmentation?
Pigmentation of the skin occurs due to the excessive production of melanin. Hyperpigmentation is not only cosmetic. It could also be a sign of an autoimmune condition, hormonal imbalance, cellular dysfunction, pre-diabetic stage, and altered cholesterol levels.
It can be patchy/spotted or diffuse and its severity depending upon the level and amount of melanin deposited at varied depth of skin layers. It is also a feature of aging. Sun exposure is one of the main causes and pigmentation needs treatment, unlike tanning which generally gets better with regular application of sunscreen.
