    When to use a serum? and 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.
    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.

    This was a bonus product included in my order. I have replaced this when I re-ordered. I had oily skin and since using this with my Alpha Fluid I have noticed a smoothing of wrinkles around my lips and between my brows.

    Perfect addition to face cream
    I've used this amazing booster - previously called YonKa Serum - for years. It never leaves your face oily but fully boosts the suppleness of your skin - I add to my daily moisture cream (Pompelmouse) every day during the dry winter.

    A must have
    This little bottle of goodness has worked wonders for my dry dry skin. I use it alone or add to any of the moisturizers and it really makes a difference. It's my Yonka must have!
