How long does a boat usually last?

It depends on how much product you use and how often. The reference dose is one pulse with the dispenser. The 1 2 3 routines are made to finish at the same time in 2 - 3 months if you use all three steps morning and night.

1 push is equivalent to about 0.15-0.25 ml. The eye contour is 15 ml, the serum is 30 ml and the moisturizer is 50 ml.
