Apply Serum C20 alone or combined with your usual skin cream daily or as an intensive course of treatment.
Every morning, warm 6 - 8 drops in your hands. Inhale the invigorating, energizing scent and apply with light motions on a clean face and neck.
Ideally, you would like to use after Yon-Ka Lotion (apply to skin still damp from the lotion to lock in hydration).
For those with oily skin, warm 4 drops of this invigorating serum in your hands before applying it to the face.
Intensive course of treatment: Follow the same method above morning and evening.
