DropBrigt® PER | Phenylethyl Resorcinol

DropBright® PER is a powerful whitening and antioxidant ingredient designed to target pigmentation and uneven skin tone effectively. Derived synthetically, Phenylethyl Resorcinol inhibits melanin production by acting on tyrosinase, an enzyme critical for melanin synthesis. Its exceptional stability and high efficacy make it ideal for skin-brightening formulations aimed at reducing hyperpigmentation, dark spots, and uneven skin tone.
