Booster Hydra +
    Purchase Booster Hydra +
    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. Mixed with your day cream, it keeps makeup fresh and long-lasting.

    How does the 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 do I use the 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.

    Really works!
    I received the Hydra + as a free gift in my last purchase. I didn't start using the product until a month after when I got a facial done. I have really dry skin and my esthetician suggested I should use a product that hydrates my face more. So that is when I decided to add the booster to my moisturizer and WOW! It made a huge difference! My face was breaking out really bad from stress and dry skin, after I started using the booster to my routine I noticed my face repairing itself back to normal and hydrated. I also use the Lait Nettoyant, Lotion PS, and the Hydra 1 in my routine. I use a small dime size of the hydra 1 and a pump of the Hydra booster and rub to my face. It also smells really good and feels refreshing on my face. Love this product!

    Fast absorbing and works immediately
    I’ve been using this booster for about a week. I’ve paired it up with Creme 28 and Vital Defense, not sure which one I like better but I definitely saw the difference when I used it. My ‘frowning’ wrinkles looked smoother and not as deep whenever I’ve used the booster. I apply it in the morning. Night; I use phyto 52 with the Lift+ booster.
