Abstract
Hyperpigmentation is the most common complaint in the age group 40-45years, seeking consultation for skin disorders. Hydroquinone is a commonly used depigmenting agent in clinical practice for treating hyperpigmentation. Prolonged use of hydroquinone has been associated with cancer risk and exogenous ochronosis. The CARES (The Coronavirus Aid, Relief, and Economic Security Act) Act of 2020has instituted significant changes to hydroquinone containing OTC (over the counter) products, and consequently, many hydroquinone-based OTC products had to be withdrawn from the market. Henceforth, products containing hydroquinone would need US Food and Drug Administration approval via new drug application pathways for commercialization. Alternative treatment options to hydroquinone in clinical practice are reviewed in this paper with regard to their safety and efficacy vis a vis hydroquinone. Also, new potential treatment options such as thiamidol, Polypodium leucotomos, and glutathione are discussed. The review shows that these alternative depigmenting agents can be rationally combined to achieve desired treatment goals in the management of hyperpigmentation.
