ATOSALT Intensive Cream [Skin Barrier Repair & Temporary Relief of Dryness-Induced Itchiness]:

Recommended when you want to restore a damaged skin barrier.

Yes — the clinical data proves it. The Soothing Lotion showed a 60.2% skin-calming effect 30 minutes after application, and the Intensive Cream showed a 96.2% improvement in the damaged skin barrier 30 minutes after use.

What's more, two weeks of using ATOSALT Soothing Lotion delivered a remarkable 109.8% improvement compared with the skin's condition before irritation. In just 30 minutes, experience for yourself the energy of microorganisms condensed over ten years, together with highly concentrated natural minerals.

BAC1's key ingredient, BV1™, is used in its pure, natural state — without any artificial chemical preservatives or separate sterilization.

Over the 10-year aging process, its minerals and microorganisms reach a perfect balance on their own, developing a natural ability to preserve themselves. Independent testing has confirmed that, even without artificial sterilization or preservatives, BV1™ maintains exceptional cleanliness and stability — supported by our eco-friendly water treatment.

BV1™ is a pure natural extract, stabilized over many years through the workings of nature, and it causes no skin side effects. In primary irritation and sensitive-skin testing, the ATOSALT line was rated 'non-irritating' (irritation index 0.00–0.03), and because it excludes 20 harmful ingredients, even sensitive skin can use it with confidence.

Although the formula is very mild, we recommend it for children aged 7 and older — the stage when outdoor activity increases and skin-barrier care becomes truly important. For the highly concentrated minerals to absorb efficiently, it is best to begin once the skin has matured somewhat. (※ For infants and children under 7, we recommend a patch test on a small area before use.)

Yes — there's no need to worry. This is a temporary reaction that occurs as the highly concentrated natural minerals in our key ingredient, BV1™, absorb into weakened skin. It varies from person to person, but it usually subsides within 3–4 days, as the skin returns to a healthy state. If you feel any discomfort, we recommend using a smaller amount at first to give your skin time to adjust.

Because our products are rich in highly concentrated minerals, pilling can sometimes occur as they absorb, depending on your skin's condition. With ATOSALT Intensive Cream in particular, please don't rub it in — apply a thin layer and pat gently to aid absorption.

Use it on clean skin after cleansing or showering. For the face, we most recommend applying in the evening, without makeup, so the active ingredients can absorb fully.

Unlike products that simply blend in salt, BAC1's ATOSALT line uses SaltBiome™ technology to extract and cultivate halophilic Paleozoic native microorganisms, along with natural minerals, by aging Korean tidal-flat sea salt for ten years. Its key ingredient, BV1™, holds highly concentrated natural minerals together with the powerful energy of these microorganisms — delivering clinical results on an entirely different level.

The ATOSALT line works best when the two are used together. After delivering instant calm and moisture with the Soothing Lotion, layer Intensive Cream over the areas that need extra care to firmly rebuild the weakened barrier. Your skin will improve even faster.
