Skin Whitening Effects: Phenylethyl Resorcinol is capable of inhibiting the activity of tyrosinase, an enzyme that plays a crucial role in the production of melanin in the skin. By inhibiting the activity of this enzyme, Phenylethyl Resorcinol can reduce the formation of melanin, achieving the effect of whitening the skin.

Antioxidant Properties: It is also an effective antioxidant, capable of neutralizing free radicals generated from exposure to UV light or other environmental factors, thereby reducing skin damage caused by oxidative stress. This, to some extent, slows down the process of skin aging.

Skin Tone Brightening: In addition to whitening effects, Phenylethyl Resorcinol is also used to improve uneven skin tone and brighten the skin, making the complexion appear more uniform and luminous.
