Description
Does your skin feel tight, rough or dull by the end of the day, even with your regular moisturiser? It is most likely lacking water. The Yon-Ka Hydra+ Booster is an ultra-concentrated hydrating concentrate from the Boosters range that you simply blend into your usual day or night cream. In one easy step you reinforce the moisturising action of the care you already love, without changing your routine. Ideal for every skin type that needs extra hydration, and especially for dry and dehydrated skin.
How it works
The strength lies in the combination of water-binding and soothing actives. Sodium PCA is a natural moisturising factor that helps hold water in the upper layers of the skin. Vegetable glycerin keeps the skin supple and comfortable, while blackcurrant bud extract (Ribes nigrum) and raspberry juice (Rubus idaeus) provide a calming effect. The formula is further enriched with vitamins, including ascorbic acid and calcium pantothenate, for a fresh, natural glow. The 15 ml bottle is small but highly concentrated: a few drops per application are enough.
Texture and how to use it in your routine
The texture is light and fluid, with a 100 % natural blackcurrant scent that turns application into a small ritual. Use the booster as a one-month course, morning and/or evening. Cleanse first with Lait Nettoyant or Gel Nettoyant, refresh with Lotion Yon-Ka PS or PNG, then blend a few drops into your cream, for example Hydra N°1 Crème or Nutri Defense. Mixed into your day cream it also helps make-up stay fresh for longer. Do not apply the booster neat on the skin.
Frequently asked questions
Which skin type is the Hydra+ Booster for?
For any skin that needs extra hydration, particularly dry and dehydrated skin. Oily skin can be dehydrated too and will also benefit from this booster.
How do I combine it with the Lotion and my cream?
Cleanse, mist on Lotion Yon-Ka PS (dry skin) or PNG (normal to oily skin), then blend a few drops of the booster into your day or night cream in the palm of your hand, for example Hydra N°1 Crème.
How long does a 15 ml bottle last?
Using a few drops per application, 15 ml generally lasts around a month, exactly the length of one course. Repeat the course whenever your skin feels thirsty again.
Operation
The Hydra+ Booster is a highly concentrated hydrating concentrate that you blend into your usual cream. Sodium PCA is a natural moisturising factor that helps hold water in the upper layers of the skin, while vegetable glycerin keeps the skin supple and comfortable. Blackcurrant bud extract (Ribes nigrum) and raspberry juice (Rubus idaeus) bring a calming effect, and vitamins including ascorbic acid and calcium pantothenate support a fresh, natural glow. In one step it reinforces the moisturising action of the day or night care you already use.
Application
Use the booster as a course of about one month, morning and/or evening. Cleanse first with Lait Nettoyant or Gel Nettoyant and refresh with Lotion Yon-Ka PS or PNG. Then dispense a few drops of the booster into the palm of your hand, blend them into your usual day or night cream and apply to face and neck. Do not apply the booster neat on the skin.
Result
Skin feels instantly more comfortable and supple, and the tight, rough sensation eases. After a course of around one month the complexion looks fresher and less dull, and your familiar cream keeps skin hydrated noticeably longer. Blended into your day cream, make-up also stays fresh for longer.

Frequently asked questions
- What is the Yon-Ka Hydra+ Booster and who is it for?
- The Yon-Ka Hydra+ Booster is an ultra-concentrated, vitamin-enriched hydrating booster designed for all skin types that need extra moisture — especially dry and dehydrated skin. It immediately reduces tightness and roughness, leaving skin supple and radiant. If your skin feels uncomfortable or dull, this 15ml booster is a great addition to your routine.
- How do I use the Yon-Ka Hydra+ Booster correctly?
- Use the Yon-Ka Hydra+ Booster morning and/or evening for one month. After cleansing and applying Lotion Yon-Ka, simply mix a few drops into your usual day or night cream and apply to face and neck. When mixed with your day cream, it also helps keep your makeup looking fresh and flawless throughout the day.
- What does the Yon-Ka Hydra+ Booster actually do for my skin?
- The Yon-Ka Hydra+ Booster deeply moisturizes and soothes thanks to PCA and vegetable glycerin, which bind and lock in moisture while forming a protective barrier against moisture loss. Blackcurrant and raspberry extracts provide a calming, antioxidant effect. The result is visibly softer, more comfortable and naturally radiant skin.
- Can I use the Hydra+ Booster with my existing skincare products?
- Absolutely — the Yon-Ka Hydra+ Booster is designed to be mixed directly into your existing day or night cream, boosting its hydrating power without replacing it. It works with virtually any moisturizer and is suitable for all skin types. It enhances rather than disrupts your current routine, making it an easy upgrade.
- Why choose the Yon-Ka Hydra+ Booster over a regular moisturizer?
- Unlike a standard moisturizer, the Yon-Ka Hydra+ Booster is ultra-concentrated and vitamin-enriched, meaning a few drops significantly amplify the effectiveness of your usual cream. It targets dehydration at a deeper level through PCA and vegetable glycerin, while the 100% natural blackcurrant scent makes the experience feel genuinely luxurious.
