Abstract
This study examines the photostability of retinol and retinyl palmitate, finding they break down rapidly when exposed to UV radiation in the 290―400 nm range. This severely reduces their concentrations in finished formulations. However, when combined with ethylhexyl methoxycrylene, these retinoids are shown to be protected against photodegradation, thus preserving their concentrations both during the manufacturing process and following application to the skin.
