The Day & Night idea

"Day and night" is a pretty bright idea brought by skincare marketers. It's a consumer insight where ladies look after their skin before work in the morning and before sleep at night. Skincare people makes use of this usage habit to offer holistic solution during the day and night. Can this consumer behaviour "extended" to the usage of beauty related health foods ? Nestle offers such a yoghurt product claimed to have beautifying effect. But high chance is people either forget to eat either the day yoghurt (too rush in the morning) or the night yoghurt (too tired at night). It just takes too much commitment to turn this into a routine or a habit.
