How long does self tanner last (Chanel, Clarins, Dove)?

the gradual tanners last for about a week after you use them for three days... that's why they are gradual you have to keep on using them|||Chanel and Clarins only last until you wash it off with soap and water. Dove gradually forms by helping you produce more melanin, thus creating a natural tan that last as long as you keep going out into the sun for some vitamin D.
