    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.

    Best thing ever!
    My skin has been crazy dry and changing so quickly post covid. I was recommended this product during a facial and I am so thankful I listened! My face feels absolutely amazing, and my makeup on days I decide to wear it goes on so smooth and beautiful! Hydrated skin is the secret to looking young forever!
    Nutri Booster Oil
    This is a new product for me, and I absolutely love it! It absorbs quickly, leaves my skin soft and glowing, and doesn't cause reactions or breakouts for my sensitive, cystic acne-prone skin. It also doubles as a great nail and cuticle oil. The scent is so lovely and calming! A little goes a long way, so I found it to be worth the investment. I will definitely re-order this booster.

    Best facial oil!!!
    I’ve tried so many different brands of oils and this one is my absolute favorite. It really sinks into the skin instead of just making me greasy or sitting on top of my skin

    I add this to Pamplemousse every day and it makes all the difference!

    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!
