Frequently Asked Questions
Is Booster Hydra + suitable for sensitive skin?
Booster Hydra + is tolerance tested by dermatologists for all skin types, including sensitive skin. It is a water-based concentrate formulated to boost hydration without clogging pores, and its gentle plant extracts such as blackcurrant, raspberry and horse chestnut support skin comfort and suppleness. Because it is designed to be mixed with your usual Yon-Ka Paris moisturizer, it minimizes the risk of irritation that can come from layering multiple heavy products. Those with very reactive skin should still patch test one drop on the inner forearm and consult a dermatologist if they have a diagnosed skin condition or are using prescription topical treatments.
How do I use Booster Hydra + with my moisturizer?
Use Booster Hydra + to enhance your moisturizer by mixing 3-4 drops directly into a pea-sized amount of your Yon-Ka Paris cream. The formula is water-based and designed to increase a moisturizer's hydrating effect by 30 percent, so blending it in delivers both immediate hydration and improved performance from your cream. This method is suitable for morning and evening routines and for quick boosts during seasonal changes. Those with very reactive skin should still patch test one drop on the inner forearm and consult a dermatologist if they have a diagnosed skin condition or are using prescription topical treatments.
Will Booster Hydra + clog my pores or cause breakouts?
Booster Hydra + is a water-based concentrate specifically formulated not to clog pores. Its light texture and non-comedogenic design make it suitable for dry and dehydrated skin types that still need breathable hydration. The formula enhances moisturizer performance without adding heavy oils or occlusive ingredients that can trap sebum. People prone to acne should monitor how their skin responds when mixing any booster with richer creams and can opt to blend Booster Hydra + with a lightweight gel moisturizer to maintain hydration without increasing pore congestion.
Can I use Booster Hydra + during travel and is the 15 ml size allowed on flights?
Yes. Booster Hydra + is ideal for travel because its water-based concentrate delivers rapid hydration to counteract dehydration from air travel and changing climates. The 15 ml vial is under the standard 100 ml carry-on liquid limit used by many airlines, making it convenient for in-flight or destination use. Mix 3-4 drops with your moisturizer during a flight to reduce tautness and refresh skin, and store the vial upright in a travel pouch to prevent leakage. If you have very dry skin while traveling, use it more frequently or mix it under a more nourishing Yon-Ka Paris cream.
How soon will I notice hydration or texture improvements with Booster Hydra +?
You should notice an immediate improvement in skin comfort and suppleness after the first application because Booster Hydra + provides concentrated moisture and reduces the feeling of tautness. Regular use often leads to smoother texture and diminished rough spots over days to weeks as the skin’s hydration levels improve. The product is formulated to boost a moisturizer’s hydration by 30 percent, which supports progressive visible benefits. Individual results vary based on baseline skin condition, frequency of use, and complementary products in your routine.
Who benefits most from using Booster Hydra +?
Booster Hydra + is best for people with dehydrated skin seeking an immediate and measurable hydration boost. It is especially effective for those experiencing seasonal dehydration, travel-related dehydration, or temporary tautness. Because it is tolerance tested for sensitive skin and non-comedogenic, individuals with sensitive or combination skin who want extra hydration without heaviness also benefit. For those with oilier skin types that do not require intensive hydration; use sparingly paired with a lightweight moisturizer.
Can men use Booster Hydra + and does their routine differ?
Yes. Booster Hydra + is suitable for men and integrates seamlessly into a masculine skincare routine. Mix 3-4 drops into your Yon-Ka Paris moisturizer after cleansing to restore hydration, soothe rough spots and reduce the sensation of tightness. Men who shave may find it particularly helpful applied post-shave to calm and rehydrate skin. The application frequency and amount remain the same as for anyone else; adjust the dose based on skin dehydration level and personal preference for texture and finish.
Can I mix Booster Hydra + with active serums or retinol?
Booster Hydra + mixes well with your moisturizer in routines that include active treatments. Its water-based composition helps deliver hydration alongside serums or actives, but when using potent ingredients such as retinol or acids, apply those actives first and allow them to absorb before adding Booster Hydra + and your cream to reduce potential irritation. For very reactive skin, perform a patch test and introduce combinations gradually. If you use prescription topicals, consult your dermatologist about the optimal layering order.
What makes Booster Hydra + different from other Yon-Ka Paris boosters?
Booster Hydra + is specifically formulated as an intensely hydrating, water-based concentrate that increases a moisturizer’s hydrating performance by 30 percent. It is enhanced with blackcurrant, raspberry and horse chestnut extracts to improve comfort and skin suppleness, and it will not clog pores. This focus on immediate, measurable hydration and a light texture distinguishes it from richer or oil-based boosters intended for different concerns. Choose Booster Hydra + when your priority is quick, breathable hydration without adding heaviness to your routine.
How long will a 15 ml vial of Booster Hydra + last?
It depends on how often and how much you use, but a 15 ml vial typically provides multiple weeks of applications for daily use. Because Booster Hydra + is a concentrate, most people use only a few drops per application mixed into a moisturizer, which stretches the product further than a full-size cream. If you use it several times daily or apply larger amounts to very dry areas, the vial will be consumed more quickly. Consider your routine frequency and droplet amount to estimate how long a single vial will last for you.
