Pigmentation is the colouring of your skin. It is a skin condition where patches of the skin turn into a darker shade of colour due to excessive presence of melanin, found on skin surface. Melanin is produced by melanocytes and functions as miniature umbrellas to skin cells to protect the skin from sun and UV damages.
Types of hyperpigmentation
Epidermal (surface layer): Tends to be tan, brown, or dark brown in colour and it may take months to years to get rid of post-inflammatory hyperpigmentation without treatment.
Dermis (inner layer of skin): Tends to be bluish-grey in colour and may be permanent if it is left untreated.
