Hyperpigmentation is caused by an increase in melanin production by the melanocyte cells in the skin.
This occurs following injury (such as hair removal), but sun damage, hormonal changes, and genetics also play a role.
Treatments for hyperpigmentation
To treat hyperpigmentation, the melanocytes need to be stabilised.
Most treatments available in the market focus on the superficial layers of the skin and this often results in more hyperpigmentation later on.
Effective treatment involves stabilisation of melanocytes in conjunction with restoring the barrier function of skin and eliminating sebum which irritates the melanocytes.
Using hydroquinone to bleach and blend the melanin production is controlled.
This is used temporarily before switching to a non-hydroquinone approach to maintain the results.
In some cases, further treatment acceleration is achieved with a chemical peel or topical exfoliant.
