    In the morning and/or evening for one month, after cleansing and spraying on Lotion Yon-Ka, add a few drops of the concentrate to your usual cream, then apply to the face and neck.

    How does a serum work?
    Yon-Ka Boosters are not serums. A booster is added to a moisturizer to boost it's function or give it a complimentary action.
    When to use a serum?
    Add 1-2 pumps of a booster to your usual Yon-Ka moisturizer in morning and/or evening.
     
    Why should I use a serum?
    Boosters are a great way to customize your Yon-Ka homecare regimen. It's like adding a shot of active ingredients to your moisturizer.

    Must have for dry skin
    This product is perfect for those who have mature dry skin. I add a few drops to any Yonka product to make it extra moisturizing. Love the way it feels and smells. I plan to add more booster products to my Yonka skin care routine.

    Love!
    This product feels so good on the skin. I typically add a drop to other creams for added moisture.

    I see the difference
    Makes me feel good to mix this with my sunscreen moisturizer every morning as I know I'm protecting my skin each day. Also, I feel my skin looking brighter as I use this.
