There is no clear answer yet. In theory, the whitening effect of 377 is more direct.
377 is the common name of phenethyl resorcinol, which is a new type of whitening substance obtained by chemically modifying the natural whitening ingredient ginseng in the pine tower of European red pine.
Niacinamide is a water-soluble vitamin that is often used in skin care products to brighten skin, improve or prevent dull skin, yellowing, etc.

Although both 377 and niacinamide are whitening agents, the pathways for their whitening effect are different:
377: By inhibiting tyrosinase activity and a certain degree of antioxidant effect, inhibits the formation of melanin, thereby achieving whitening Light spot effect;
Niacinamide: Inhibits the transfer of melanin from melanocytes to stratum corneum cells, reducing epidermal pigmentation, thereby achieving whitening and lightening Spot effect.
Theoretically speaking, the whitening effect of 377 is more direct, and it can achieve the lightening effect from the source of tyrosinase inhibition.
However, there is no authoritative experiment comparing the whitening effects of 377 and niacinamide, so there is no clear conclusion for the time being.
