How it works

The C-Niacin Toning Ampoule is a 50ml ampoule, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named seventh on its own ingredient list. The same list carries Dipotassium Glycyrrhizate, Allantoin and Bioflavonoids, so the active is not the only thing on it worth naming. How much of the Niacinamide stays on the skin, and for how long, is decided by the ampoule format rather than by the list alone. This is the Original Korean Formula, the ampoule Isntree sells in Korea, Niacinamide and all.

How to use

  1. Use the C-Niacin Toning Ampoule after toner and before moisturizer, morning and evening.
  2. Half a dropper, or two or three drops, is the amount for a whole face. Press it in rather than spreading it thin.
  3. It sits between the toner and the moisturizer, and it is the layer most worth leaving alone for a minute before anything covers it.
  4. Twice a day, every day. Do not use it as a spot application on one area; an ampoule is a routine step, not a targeted dose.

Worth knowing

  • Patch test this ampoule on a small area and wait a day before using it more widely, especially with Niacinamide on the list.
  • Introduce this ampoule on its own for the first week, so anything your skin does is traceable to the Niacinamide rather than to three changes at once.
