377 Or Niacinamide, Which One Has Better Whitening And Spot Reduction Effect?

There is no clear answer at the moment. In theory, the whitening effect of 377 is more direct.

377 is the common name for phenethylresorcinol, a new type of whitening substance obtained by chemically modifying the natural whitening ingredient silver pine pine from the European red pine pine tower.

Niacinamide is a water-soluble vitamin that is often used in skincare products to brighten skin tone and improve or prevent dullness and yellowing of the skin.

Although both 377 and niacinamide are whitening agents, they have different pathways to achieve whitening effects.

377: inhibits the formation of melanin through the inhibition of tyrosinase activity and a certain degree of antioxidant effect, thus achieving whitening and light spot effects.

Niacinamide: inhibits the transfer of melanin from melanocytes to cells in the stratum corneum to reduce epidermal pigmentation, thus achieving whitening and light spot effects.

Theoretically, the whitening effect of 377 is more direct, and it can achieve the light spot effect from the source of tyrosinase inhibition.

However, there is no authoritative experiment to compare the whitening effect of 377 and niacinamide, so there is no clear conclusion for the time being.
