Skin darkening and pigmentation happens due to the mal function of the melanin cells on the skin surface. These cells are responsible in maintaining the skin tone and color. They also are responsible in ensuring an even skin tone, across the entire surface area of the skin. Melanin pigments need nutrients and vitamins for their functioning. People will have to ensure that these nutrients are available in adequate quantities. These nutrients can be provided through the dietary food intake of the people. The nutrients present in food items are absorbed by blood and are supplied to the skin cells. If the nutrient supply is insufficient, melanin pigments become inefficient and this can result in overall skin darkening and skin pigmentation. Supplementary nutrients can be provided to the melanin pigments via ingested compounds and also by external application of skin maintenance creams and lotions. Nutrients are also essential for the rejuvenation ability of melanin cells, especially vitamins. If these vitamins are not provided to the cells they become dormant and lie in isolated concentrations on damaged parts of the skin. These are visible in the forms of skin pigmentation and ski darkening. Nutrient supply is vital for prevention of skin darkening and skin
Skin coloration and tone is maintained for a larger part of the life cycle in people. When people approach their old age, all parts of their bodies show signs of slowing down and effects of constant wear and tear. Skin is no exception to this phenomenon. In fact, skin is one of the most over worked parts of the body. The function of skin cells is to protect the body against external damage, while maintaining an even skin tone at the same time. Due to wear and tear skin changes take place as the skin cells display decreased efficiency. They no longer are capable of functioning to their fullest ability. This can also be visibly seen as the skin becomes dry and parched. There are any wrinkles on the skin and wounds take a longer time to heal. Skin pigmentation occurs in isolated parts and gradually spreads to other parts of the skin also. This type of natural degeneration in the functioning of the skin is unavoidable and inevitable. Apart from old age and wear and tear, skin changes can also be caused by various other reasons.

Skin spots and skin pigmentation is the same and they appear on the damaged parts of the skin. Skin is constantly bombarded by pollutants, impurities and external attacks. The skin layer offers protection to the body against theses external attacks and impurities. The skin cells are able to withstand a lot of wear and tear; they also have the ability to repel some of these attacks; absorb the impact of these attacks on their own without affecting the internal parts, along with the ability to rejuvenate itself and heal some of the wounds. There are many specialized cells in the skin that aid in the healing process and melanin pigments are one such group of cells.
