2. Please follow the adaptation guide.
*Use it every other day in the evening as an adaptation period for the 1st and 2nd week, and apply an amount equal to the size of a grain of rice onto the desired area.
*From the 3rd week onwards, it is the stabilization period, so apply an appropriate amount to the entire face in a pea-sized amount when using it every evening.

As retinol acts on the skin, it may cause irritation (redness, peeling, and burning).
This phenomenon indicates that the product is working normally, and if irritation persists, reduce the frequency or discontinue use.
