Hexylresorcinol is a synthetic phenolic compound with antiseptic, anesthetic, and antioxidant properties, widely used in pharmaceuticals, cosmetics, and oral care products. It was first synthesized in the early 20th century and gained attention for its effectiveness in treating minor skin infections, sore throats, and wounds. In medicine, hexylresorcinol has been applied as a topical antiseptic and in lozenges for its local anesthetic effect, while in cosmetics, it is valued for its skin-lightening and antioxidant properties. Its broad-spectrum antimicrobial activity, combined with low toxicity, has made hexylresorcinol a versatile ingredient, maintaining relevance in both healthcare and personal care industries over the decades.
