Booster H Intensive Repair & Hydrating Ampoule 5ml × 5｜52.5mg Ultra-High Concentration Hyaluronic Acid · Ectoin Repair · For Device Use Only | Made in Hong Kong

Is your skin so dry that even serums can't lock in moisture? The problem isn't your skin, but rather that the hyaluronic acid concentration in ordinary skincare products is simply not enough.

Booster H Dryness Repair Hydrating Ampoule, each 5ml vial contains 52.5mg of ultra-high concentration hyaluronic acid, far exceeding typical at-home beauty serums. Combined with Ectoin for barrier repair, Panthenol (Vitamin B5) for soothing hydration, Opuntia Ficus-Indica Stem Extract for long-lasting moisture retention, and three different molecular weights of hyaluronic acid for deep-to-surface penetration, one ampoule instantly infuses the skin with abundant moisture, rebuilding a healthy, hydrated barrier, and immediately restoring plumpness and softness to dry, dehydrated skin.

✦ What problems does this ampoule solve for you?

• Long-term dry and dehydrated skin, with fine lines appearing on the forehead and around the eyes

• Daily hydrating skincare products don't last long, and skin easily becomes dry again

• Skin rapidly loses moisture in autumn/winter or air-conditioned environments

• Already own an at-home device and wish to use it with an ultra-high concentration hydrating ampoule

• Skin needs intensified hydration after using active ingredient skincare (retinol, acids)

✦ Why is Booster H one of the most effective hydrating ampoules on the market?

① 52.5mg Ultra-High Concentration Hyaluronic Acid — Numbers Speak for Themselves
Most at-home beauty serums contain only a few milligrams of hyaluronic acid per vial. Booster H, however, contains 52.5mg of hyaluronic acid in each 5ml vial. This ultra-high concentration formula ensures that each application provides a dose of hydration sufficient to truly transform skin conditions, rather than just a superficial feeling of moisture. When used with a beauty device, it further overcomes skin penetration limitations, allowing high-concentration hyaluronic acid to reach deeper skin layers.

② Triple Hyaluronic Acid for Full-Layer Hydration — Deep to Surface Coverage in One Go
Booster H utilizes three different molecular weights of hyaluronic acid for synergistic action:

• Hydrolyzed Sodium Hyaluronate: Ultra-small molecule, penetrates the stratum corneum to deeply hydrate the dermis

• Sodium Hyaluronate: Standard molecule, immediately hydrates and locks moisture in the epidermis

• Sodium Hyaluronate Crosspolymer: Cross-linked large molecule, provides long-lasting moisture retention on the skin surface, reducing TEWL (Transepidermal Water Loss)

These three molecular weights, from small to large, cover different depths of the skin, achieving true full-layer deep hydration rather than just a single, superficial moisturizing effect.

③ Ectoin — Hydrates and Repairs the Barrier Simultaneously
Ectoin is a natural amino acid derivative found in microorganisms from extreme environments. It protects skin cells from environmental stressors (dryness, air conditioning, temperature fluctuations) while enhancing skin moisture, repairing damaged barriers, and soothing sensitive discomfort caused by dryness. Ectoin in Booster H, in synergy with ultra-high concentration hyaluronic acid, not only provides immediate hydration but also helps the skin build a stronger, more resilient moisture barrier, leading to more lasting and stable hydration results.

④ Opuntia Ficus-Indica Stem Extract — The Desert Plant's Secret to Extreme Moisture Retention
Cacti thrive in extremely dry environments, and their stem extract is rich in natural polysaccharides and mucilage. This forms a thin, lightweight moisture-locking film on the skin's surface, effectively preventing moisture evaporation, while also possessing soothing and anti-inflammatory properties. This allows replenished moisture to remain in the skin for longer periods, rather than rapidly evaporating.

⑤ Panthenol (Vitamin B5) — Dual Action Soothing for Hydration and Repair
Panthenol is a multi-functional ingredient widely trusted by dermatologists. It penetrates the skin and converts into Pantothenic Acid, promoting skin cell repair and regeneration, while also providing moisturizing, soothing, and anti-inflammatory benefits. In synergy with hyaluronic acid and Ectoin, Booster H addresses skin repair needs while hydrating.

✦ Benefits

• Instant Deep Hydration: 52.5mg ultra-high concentration hyaluronic acid penetrates all layers for deep hydration.

• Long-lasting Moisture Lock: Opuntia Ficus-Indica Stem Extract + cross-linked hyaluronic acid form a persistent moisture barrier.

• Repairs Skin Barrier: Ectoin protects skin cells from environmental stress and repairs dry, damaged barriers.

• Soothes Dry Discomfort: Panthenol + Ectoin synergistically soothe sensitivity and stinging caused by dryness.

• Improves Fine Lines: Continuous hydration plumps deep skin layers, improving dry fine lines and dull skin tone.

✦ Texture

Refreshing, clear, watery serum with a light, fluid texture. Fragrance-free and colorless. Skin feels immediately plumped and hydrated upon application, non-sticky and leaves no residue. Glides smoothly when used with a beauty device. Suitable for all skin types, especially dry and sensitive skin.

✦ Active Ingredients

Ectoin
A natural amino acid derivative sourced from microorganisms that thrive in extreme environments such as high salt, high temperature, and strong UV radiation, where it protects cellular structures from environmental damage. In skincare, Ectoin shields skin cells from dryness and environmental irritants, boosts skin hydration, reduces TEWL, repairs the skin barrier, and soothes dry and sensitive discomfort. It is a gentle yet highly effective ingredient commonly found in dermatological and medical beauty repair formulas.

Panthenol (Vitamin B5)
The alcohol form of Vitamin B5, which converts into Pantothenic Acid upon penetrating the skin. It offers multiple benefits including moisturizing, promoting cell repair and regeneration, soothing inflammation, and strengthening the skin barrier. When used with hyaluronic acid, it significantly enhances overall hydration and repair efficacy.

Hyaluronic Acid (Triple Hyaluronic Acid Complex)
Comprising Hydrolyzed Sodium Hyaluronate (ultra-small molecules for deep penetration), Sodium Hyaluronate (standard molecules for immediate hydration), and Sodium Hyaluronate Crosspolymer (cross-linked large molecules for long-lasting moisture retention). These three molecular weights provide full-layer coverage from the dermis to the skin surface. With a total concentration of 52.5mg/5ml, this complex is the core hydrating advantage of Booster H.

Opuntia Ficus-Indica Stem Extract
Derived from the stem of the prickly pear cactus, this extract is rich in natural polysaccharides and mucilage. It forms a thin, breathable moisture-locking film on the skin's surface, effectively preventing moisture evaporation. It also possesses natural soothing and anti-inflammatory properties, helping the skin cope with dry environmental stress.

✦ How to Open the Vial

1. Follow the arrow indicator on the cap to identify the opening position

2. Lift the cap and peel off the aluminum seal

3. Remove the grey stopper

4. Attach the included transparent ampoule dropper (securely)

✦ How to Use

With a home beauty device (recommended):

1. After cleansing, gently press the dropper to dispense an appropriate amount of serum and apply it to the skin.

2. Gently massage with the beauty device until the product is fully absorbed by the face.

3. Finish by applying a cream or lotion.

4. Dosage: 1/3 – 1/2 vial per use

Direct use without a beauty device:

1. After cleansing, apply an appropriate amount of serum to the face.

2. Gently pat until absorbed, then proceed with subsequent skincare steps.

3. One vial can be used for approximately one week.

⚠️ For hygiene reasons, it is recommended to use up the opened vial as soon as possible, preferably within one week. Before use, it is advisable to perform a patch test behind the ear or on the inner forearm. Avoid use around the eyes and on broken skin.

✦ Formulator Q&A

Q: How much should I use each time when combining it with a beauty device?

A: Adjust according to your face size and the device's mode. Generally, a 10-minute treatment requires about half a vial. You can re-seal the vial with the stopper and continue using it later. For hygiene reasons, it's recommended to use up the opened vial as soon as possible, ideally within one week.

Q: How often should I use it per week?

A: This depends on your skin's needs:

Daily Maintenance: Use 1–2 times per week with a beauty device to continuously replenish skin moisture and maintain a hydrated barrier.

Rapid Dryness Improvement: If your skin is particularly dry and dehydrated (due to seasonal changes, post-long-haul travel, or sun exposure), you can use it daily for several consecutive days until your skin condition significantly improves, then revert to the regular maintenance frequency.

Q: If I don't have a home beauty device, how effective is Booster H for direct use?

A: It is equally effective when used directly as a high-performance serum. The 52.5mg ultra-high concentration of hyaluronic acid itself far exceeds that of typical skincare serums, providing noticeable immediate hydration results upon direct application. Using it with a beauty device further breaks through penetration limitations, allowing high-concentration ingredients to reach target areas of the skin more deeply, enhancing the effects twofold.

Q: Can Booster H be used with Booster S?

A: Yes, they complement each other. If you need both hydration and sensitive skin repair, it is recommended to first use Booster H for deep hydration to strengthen the skin's base. After it absorbs, then use Booster S for repair and soothing. Use the two products sequentially rather than mixing them, allowing each active ingredient to fully exert its efficacy.

Q: Can I mix multiple ampoules?

A: It is recommended to use them sequentially rather than mixing them directly. First, use a hydrating ampoule (like Booster H) to strengthen the skin's base, then use other functional ampoules (e.g., for brightening, oil control, or fine lines) to ensure each ingredient is fully absorbed by the skin for optimal results.

✦ Why choose Booster H?

The most common problem with hydrating skincare isn't "not doing enough," but rather "the concentration isn't high enough." The hyaluronic acid content in ordinary serums is often merely an embellishment in the formula, far from the dosage needed to truly change the skin's moisture state. Booster H directly answers this question with the number 52.5mg — this isn't an ordinary moisturizing serum, but a high-concentration hydrating solution designed to truly solve dryness problems.

Hydrated skin is the foundation of all skincare efficacy.

Booster H is developed by a team of Hong Kong formulators and insists on local manufacturing in Hong Kong. Each ampoule embodies dedication to skincare ingredients and a commitment to your skin.
