Pigmentation

Pigment melanin gives our skin protection against harmful ultraviolet rays. Melanin production can increase or decrease beyond normal. This creates a change in the skin color. The overproduction of melanin, or hyperpigmentation (dark spots), is related to UV light, acne scarring, hormonal changes, nutritional deficiency or prescription drugs. The hypopigmentation (white spots) is often associated with the disease known as vitiligo but can also occur as a result of injury.

Hyperpigmentation results from the increased deposition of melanin.

It causes skin to become darker in patches. Melanin is part of skin’s barrier defence system. It protects against exposure to UVR. Pigmented spots are almost always the result of excessisve stimulation by sunlight. Pigmentation should be considered to be a warning sign from the body that the affected area has received too much sun damage. DNA damage by UVR is the major aggravating factor of excessive pigmentation. Although sunlight is essential for human life, daily exposure to the sun over a lifetime is a major cause of skin damage. It leads to pigmentation, wrinkling and skin cancer. Sun exposure causes free radical damage to the cells. It forces the aging process into an accelerated pace. By exposing skin to the sun, the level of vitamin C in the skin drops by 30%. In addition, UVR deactivates vitamin A receptors. Vitamin A is required for cell replication. Free radicals cause abnormal melanin production and impaired DNA/cell replication.
