Abstract
Skin hyperpigmentation is caused by several factors that upregulate melanogenesis.
Plants and natural products with skin-whitening effects are gaining interest among
consumers and researchers because they are perceived to be milder, safer, and healthier
than synthetic alternatives. This review extensively summarizes the status of plants
and natural products currently used in skin-whitening cosmetics as well as potential
candidates for future use, because the scope of natural choices for efficient treatment
of skin hyperpigmentation is rapidly widening. Biological activities of plants and
natural extracts are therefore available for cosmetic formulators and dermatologists
interested in naturally derived ingredients for skin hyperpigmentation treatment and
in accordance with the consumersʼ preferences and expectations upon natural cosmetic
products.
