Melanogensisis, A Complex Mechanism

Skin disorders such as brown spots, sun spots, and melasma strongly affect peoples equality of life and may impact their self-confidence. The skin produces pigments to protect the body from radiation from solar ultraviolet, infrared and visible light, blue light, environmental pollution, and mechanical injury. Dermatologists use the Fitzpatrick scale to determine skin pigmentation in six phototypes (I‐VI) by grading swelling and acquired pigmentation after exposure to UV radiation (skin's ability to tan). Hyperpigmentation on those with Fitzpatrick skin type III and above are trickier to treat as the skin naturally produces more melanin as a form of protection. Therefore, aggressive treatments using laser and hyrdroquinone may result in adverse reactions, including post inflamatory hyperpigmentaion (PIH), leaving many in worst conditions than before. Understanding the complex mechanism of melanin production and the various critical triggers so that we can focus on prevention and more effective treatment.
