Like with all vitamins, they leave your body after a certain time period (much quicker than supplements created to solve dysfunction like the Radiance Powder for example).Use the Reforming Liquid as a vitamin booster, whenever your skin needs glow, a hydrating pick me up or is on the dull side. Vitamins are not created to be taken every day all year round and should be adapted to the season, your lifestyle and food you are currently consuming.Use summers to combat dryness from the sun, use winters to put glow and color back into the look of skin, use whenever you feel your skin and body needs extra nourishment, care and plumpness.
