Apply Yon-Ka Serum C20 alone or combined with your usual skin cream daily or as an intensive course of treatment to increase skin radiance, fight the passage of time, and combat wrinkles and dark spots. Every morning, warm 3- 5 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 2 -3 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. It can be used as an express radiance treatment for up to 5 days or as an intensive program ranging from 4 to 8 weeks. May also be used post-procedure (injections, micro-needling, etc.).
