Kaine Kombu Barrier Ampoule

Kombucha-powered hydration from within with 73% fermented tea water

A barrier-strengthening ampoule formulated with 73% Jeju kombucha ferment filtrate. Rich in vitamin C, the kombucha ferment revitalizes tired, lackluster skin, while 5% panthenol intensively soothes irritation. 1% ceramide liposomes work to reinforce a compromised skin barrier and lock in moisture, addressing both inner dryness and rough texture at once.

Visible barrier improvement after just one use

Clinical testing showed a 46.49% improvement in skin barrier function after a single application. Dermatologist-tested on sensitive skin with a non-irritating result, making it safe for even reactive complexions.

For hydration that builds from the inside out

The fast-absorbing, high-adherence texture delivers an inner glow as it sinks in. Beyond the hero ingredients, the formula includes betaine for moisture support, allantoin for calming, 8 types of hyaluronic acid, and squalane to smooth and refine skin texture. A go-to treatment for seasonal dryness, makeup that lifts due to dehydration, or weakened, sensitive skin in need of targeted care.

Use after toner, before moisturizer

An ampoule is your concentrated treatment step—applied after toner smooths the skin, but before you seal everything in with cream. It sits in the same spot as a serum or essence in your routine. The key is to apply it while your toner is still slightly damp, so the kombucha ferment and panthenol can absorb deeply into skin.

Morning and evening use

If dehydration and a weakened skin barrier are your main concerns, feel free to use it twice a day. In the morning, it works as a hydrating base under makeup. At night, it helps calm skin after a long day.

2–3 drops from the dropper, press gently to absorb

Dispense 2–3 drops into your palm and warm it slightly with your body heat, then smooth it over your entire face. Instead of patting, gently press your palms into your skin for faster, more seamless absorption. For extra-dry areas, feel free to layer on a second pass.

Recommended combinations by skin concern

• For deep dehydration: Layer hydration with a moisture toner → this ampoule → a hydrating cream
• For sensitized skin: After cleansing with a gentle cleanser, use this ampoule on its own, or pair it with a calming cream
• For dull complexion: Use a vitamin C serum in the morning and this ampoule at night for balanced, around-the-clock care

Storage and usage tips

Once opened, store in a cool place away from direct sunlight. After the dropper touches the formula, wipe it gently with a tissue to keep things hygienic. If you experience redness or irritation during use, discontinue and consult a dermatologist.
