Champagne Carbon “Champagne Carbon” is an all-in-one cream with a carbonic gas pack technology that has never existed before. It is a carbonic gas pack developed in collaboration with a company that holds a patent for carbonic gas packs, utilizing Japan’s first technology in this field. After three years of development, this innovative “non-rinse one-step carbonic gas pack technology” was completed. The new technology behind Champagne Carbon, developed by Cosme Maison seins mous, fuses an essence cream with a carbonic gas pack, creating a completely new category of “carbonic gas pack beauty cream” that was not available until now. This cream can replace your usual cream, and it also works as the ultimate all-in-one cream. After a bath, it serves as a high-performance skincare product that provides easy, youthful-looking skin with just one step. For busy modern individuals who love beauty, it offers five extra minutes each day to pamper your skin. By replacing your daily cream with Champagne Carbon, you’ll have the benefits of both a cream and a carbonic gas pack, eliminating the need for sheet masks. This innovative beauty cream from Seinmu’s cutting-edge technology helps you achieve beautiful skin in no time. The five skincare steps (1. Apply the carbonic gas pack and leave it for 30 minutes; 2. Rinse off; 3. Toner; 4. Essence; 5. Cream) are all completed in just one step with this cream, giving you beautiful skin effortlessly.
Champagne Carbon: A Revolutionary Technology Champagne Carbon itself is an all-in-one skincare cream. It allows you to perform a carbonic gas pack treatment on your face, neck, decolletage, and bust in just three minutes every day. This time-saving technology enables the carbonic gas pack to be completed in only three minutes, with no need for long-term application or rinsing afterward. Furthermore, Champagne Carbon is a low-irritation, ultra-high-concentration carbonic gas pack, making it suitable for those who are sensitive to the typical discomfort associated with carbonic gas packs. For the first time, Champagne Carbon introduces a dual carbonic formulation, combining 43,000 ppm ultra-fine bubble carbonated water with a patented one-step carbonic gas pack technology (with around 2,000-3,000 ppm of carbonic gas). This dual carbonic gas blend activates the skin. In the summer, Champagne Carbon is effective for moisturizing sunburned skin and addressing spots. In the winter, it provides a deeply moisturizing sensation, making it a favorite for all ages. It is a carbonic gas pack beauty cream loved across all seasons. It is a sister product to the carbonic gas lotion “Cracking W Exosome.”
Existing carbonic gas pack products all involve the steps of rinsing or peeling, which take about 30 minutes. This cumbersome process has been identified as the biggest challenge (according to surveys). Additionally, the cost is very high, with carbonic gas packs ranging from 500 yen to 2,000 yen per session. On top of this, separate skincare costs and time are required, making the overall price quite expensive. If these challenges could be overcome, many people who love carbonic gas products would find them more accessible for everyday use. It is also often misunderstood that products like canned carbonic face washes or carbonic creams are not actual carbonic gas packs, so their effectiveness in terms of carbonic gas is quite limited. What is a Carbonic Gas Pack? A carbonic gas pack is produced using patented technology. It continuously generates fresh carbonic gas on the skin, allowing the newly formed gas to penetrate and take effect. Existing carbonic gas packs are used as pre-treatment steps in skincare, requiring 30 minutes of application followed by rinsing off.

[Timing for Using Champagne Carbon]
  1. After cleansing & bare skin:
    • Bauterond → Cracking W Exosome → Champagne Carbon (Best combination)
  2. After cleansing & bare skin:
    • Champagne Carbon (Ultra time-saving, ultimate lazy beauty routine)
  3. After cleansing & bare skin:
    • Introductory serum (No oils) / Toner → Toner → Serum → Champagne Carbon → Cream
    • If Champagne Carbon alone is insufficient, it’s better to apply a cream on top afterward.
    • Since Champagne Carbon uses a patented technology that reacts with your skin, applying oils beforehand will prevent it from reacting properly, making it just a regular beauty cream.
    • For dry or aging skin, be sure to hydrate with a toner beforehand.
[How to Use]
  1. For the face and neck, or décolletage and bust, use about five pumps per area. Dispense five pumps at once and apply evenly to the targeted area.
    • Apply directly to the skin or dispense onto fingertips, then spread and gently massage in a circular motion.
    • Avoid spreading the product in your palms beforehand.
  2. The carbonic gas will react with the skin tissues and turn into a carbonic gas pack.
    • Within 10 seconds, white bubbles (carbonic gas) will appear. Quickly remove your hands and wait for the foam to develop. Leave it on for 2-3 minutes.
    • Avoid rubbing or stretching the product too thinly, as this may prevent proper foaming.
  3. The carbonic gas bubbles will disappear after 2-3 minutes. Do not rinse off; simply let it absorb as a cream.
    • This is the final step. Champagne Carbon works as an all-in-one beauty cream.
    • Besides the effects of carbonic gas, it also provides a glossy skin effect and a tightening effect for a firm, beautiful complexion.
