Abstract: A composition with a whitening effect includes artemisinic acid, and further includes nicotinamide and/or glutathione. The artemisinic acid is creatively compounded with the nicotinamide and/or the glutathione to inhibit generation or transfer of melanin in all directions at multiple angles through different approaches or mechanisms. The composition can significantly inhibit activity of tyrosinase and inhibit production of the melanin, and various active ingredients are complemented with each other to achieve a synergistic effect. Meanwhile, the composition can also enhance water solubility of the artemisinic acid and reduce local irritant toxicity caused by insolubility of the artemisinic acid to enable the artemisinic acid to have good water solubility and low local irritant toxicity while achieving the whitening effect, thereby promoting deep absorption by the skin.
