Pigmentation 美白淡斑

The overproduction of melanin, or hyperpigmentation (dark spots), is related to sun exposure (direct sunlight and artificial sunlight), acne scarring, hormonal changes, nutritional deficiency or prescription drugs. Hyperpigmentation results from the increased deposition of melanin, which causes the skin to become darker in patches. Sun exposure causes free radical damage to the cells, forcing the aging process into an accelerated pace.

黑色素过度产生或色素沉着过度（黑斑）与阳光照射（阳光直射和人造阳光），痤疮疤痕，荷尔蒙变化，营养缺乏症或处方药有关。色素沉着是由于黑色素沉积增加，导致皮肤变得更黑。太阳照射导致自由基对细胞的损害，迫使老化过程加速。
