What is pigmentation?
Pigmentation refers to skin colouring caused by melanin, a natural pigment melanocytes produce. Melanin gives skin its colour and helps protect it from the harsh UV radiation.
However, when melanocytes become damaged or overactive, they can produce excess melanin, leading to pigmentation issues such as dark spots, freckles, and uneven skin tone.
Pigmentation comes in several forms, with the most stubborn one being melasma. Read more about melasma here.
