There are several instances of skin getting darker as a result of increased melanin. Hyper pigmentation is caused by excess supply of melanin, a pigment responsible for producing color in skin areas like eyes, hands, face and hair. The intensity of the factor increases as one starts aging. This is, probably due to reduction in control over distribution and regulation of melanocyte that produces melanin.
It may be caused due to overexposure to sun rays. In few cases, skin injuries and acne may be the main reason for stimulating melanocyte. Skin inflammation is also attributed to this ailment.
When patches of skin darken due to such reasons, there are a number of treatments that can either restore the skin tone or remove the patches. The most commonly adopted treatment is laser procedure. The q-switched ruby and other pigmented lesion lasers are opted to remove the dark areas on the skin.
Bleaches are often put into application to reduce the production of melanin. An active ingredient called hydroquinone is present in bleach to lighten the patches and bring it back to normal skin tone. The results can be obtained at a faster pace. Bleach containing tretinoin and cortisone can take few months to show improvement.
At home, a paste of turmeric powder and yellow gram flour can be prepared and used on the affected areas. The solution can be used twice a day. It is advisable not to move outdoors or expose yourself to sun immediately after using the home remedy.
Hyper pigmentation is a harmless ailment that can be cured by visiting a dermatologist. Prescription bleaches and laser procedures can remove the dark patches. However, it is important to adopt a healthy diet with lots of green leafy vegetables, nuts and fruits to retain the natural tone of skin.
