4-(α-Methylbenzyl)resorcinol is primarily used in the formulation of skin care and cosmetic products due to its skin-lightening and antioxidant properties. It helps in reducing the appearance of dark spots, hyperpigmentation, and uneven skin tone by inhibiting the activity of tyrosinase, an enzyme involved in melanin production. Additionally, its antioxidant properties protect the skin from damage caused by free radicals and environmental stressors, promoting a more youthful and radiant complexion. It is also utilized in some pharmaceutical preparations for its potential anti-inflammatory and antimicrobial effects.
