Friday, 30 March 2012 | Beautifully Gorgeous
An uneven complexion, or hyperpigmentation, often is the response to an over-production of melanin. Melanin is what gives skin and hair it's colouring, will help protect skin against harmful Ultra-violet light and soaks up warmth from the sun. Unfortunately, an overproduction of melanin stimulated by excessive sun exposure, hormones, or scarring, leads to a mottled, irregular skin tone.
1) Sun exposure: When skin is frequentlysubjected toUltra-violet light, sun damage occurs. Brown spots show upresulting froman excessive amount of melanin being produced to help protect skin from Ultra-violet light.
2) Hormones: Melasma is hormone-related hyperpigmentation caused by increased hormone stimulation. It'smost commonly experienced by women who are expecting a baby (which is why it’s also known as the “mask of pregnancy”) or taking contraceptives, but could also be a reaction tomakeup or medications.
3) Post-Inflammatory Hyperpigmentation: This is the darkening of skin that’sthe outcome of scarring, which is oftenthe result of acne lesions as well as skin injuries.
