摘要
脸部不规则的色素沉着是光老化最常见的症状之一。在各种肤色的人群中,皮肤晒黑是由UVA辐射引起的。大多数防晒产品重点防止由UVB的辐射引起的皮肤晒伤。由于UVA辐射能穿透皮肤,所以防晒产品并不能防止皮肤晒黑。指出,皮肤美白最好的方法就是避免太阳光的伤害。一个好的产品不仅能将皮肤中现有的黑色素去除掉,而且还能够抑制新的黑色素产生,并防止已产生的黑色素向黑素体迁移。重点介绍了几种皮肤美白产品中的活性成分及其功效。
Irregular pigmentation of the face is one of the most common signs of photoaging. Skin tanning in people of all skin colors is due to UVA radiation. Most sunscreens focus on preventing sunburn, which is due to UVB radiation. They do not prevent tanning, since UVA radiation still strikes the skin. It is pointed out that the best method of skin lightening is avoiding sun damage. A successful treatment must remove existing pigment from the skin, shut down the manufacturing of additional melanin pigment and prevent the transfer of existing melanin pigment to the melanosomes. Several main ingredients in skin lightening products and the effect were introduced.
