Used in skincare products for its skin-lightening properties, this compound works by inhibiting tyrosinase, an enzyme involved in melanin production. It helps reduce hyperpigmentation, dark spots, and evens out skin tone. Due to its effectiveness, it was popular in whitening creams and serums. However, its use has declined in some regions because of reports linking it to leukoderma or patchy skin depigmentation in certain individuals. Despite its potency, safety concerns have led to reduced formulation in consumer cosmetics.
