Pigmentation is caused due to genetics, sun exposure, stress,insulin resistance, damage to the skin due to injury or overly aggressive skin care treatment, or even the frequent use of hair dyes.Tattoos may also cause it.

Some people also suffer from post-inflammatory hyperpigmentation, usually noticed after an acne breakout. Since the face is exposed to most of the harmful factors, especially over-exposure of the sun, hyperpigmentation doesn’t only affect the face but can occur on almost any part of the body.
