This serum is to be used preferably in the evening, after removing make-up from your face and the application of a toner or a lotion. At first, apply it 2 to 3 times a week, one drop on each cheek.
Take a few drops of serum with the supplied pipette (do not dip your fingers or other instruments in the bottle, vitamin C is fragile!)
Apply by tapping onto entire face, avoiding the eye contour
Once absorbed into the skin, continue with your usual routine of care

Smoochy tip: do not forget to use sunscreen the day after applying your serum as vitamin C increases the photo-sensitivity of the skin!
