Phenylethyl Resorcinol

Phenylethyl Resorcinol is a synthetic compound derived from pine trees. It is primarily used in skincare for its potent ability to brighten skin and reduce the appearance of hyperpigmentation. It works by inhibiting tyrosinase, an enzyme crucial for melanin production, leading to a more even skin tone.
