Serum C20


Yon-Ka's powerful brightening face serum is infused with a potent, all-natural 20% vitamin C stabilized for maximum efficacy and tolerability. Composed of 99.9% ingredients of natural origin, this dark spot serum features ascorbyl tetraisopalmitate, an all-natural, oil-soluble form of vitamin C derived from green science. Our antioxidant face serum helps defend against environmental skin aging and supports the body’s collagen synthesis to help firm skin. Native turmeric and pomegranate cells help intensify the multi-corrective actions of the vitamin C as they combine to help improve skin firmness and unify skin tone by minimizing the appearance of dark spots and illuminating the complexion. Apricot kernel oil, rich in phytosterols, helps moisturize and comfort skin.

How to use
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 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. 
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.).
