Evaluation of Hexyresorcinol vs Hydroquinone for Photoaging

Completed · Not applicable

Conditions studied: Photoaging

In brief

Photoaging is a common concern within the cosmeceutical industry with many products that are available. One frequently used product is hydroquinone that is used to even skin tone. However, hydroquinone has several shortcomings. The ingredient is controversial for its potential safety issues and it has been banned in Europe. An alternative ingredient that has emerged for its potential use is hexyresorcinol for evening skin tone. Additionally, hexylresorcinol may have other photoaging benefits such as the reduction in the appearance of fine lines. Therefore, the aim of this study is to assess how hexyresorcinol may compare to the use of hydroquinone in the setting of photoaging.
