Long-lasting cosmetics are perceived to have a good price-value ratio, as they can be used more sporadically than the conventional products. Examples include: long-lasting lipsticks, nail polishes and 24-hour moisturizers in skincare. It is now relatively common for customers to extend the time between professional skin treatments, to which the manufacturers react by selling do-it-yourself products for application at home, providing an alternative which helps people maintain the effects of professional treatments for a longer time than ever before (Lennard, 2011).
