A. Urea is one of the natural moisturizing factors and is included in Hydro Essence. Although it is not formulated in high concentrations, it is present in small amounts. If you have an allergy, it is advisable to avoid using the product. However, if you wish to test it, we recommend conducting a patch test on a small area such as the inside of your arm or behind your ear before using it.

A. This product can be used as a substitute for toner. It is recommended to apply it first right after cleansing, followed by or cream.

A. Unlike traditional water-type toners, the hydro essence texture has a certain level of viscosity, so it can be used with a cotton pad. However, compared to water-type toners, you might use a larger amount at once. Therefore, it is recommended to apply it with your hands rather than using for wiping.

A. We avoid using animal-derived ingredients and each product is labeled with specific "FREE" claims indicating the absence of animal-derived ingredients. While we have not obtained vegan certification from an external organization, the products do not contain animal-derived ingredients and have not been tested on animals.

A. The Atobarrier365 line offers moisturizing solutions specifically designed for sensitive and dry skin. Generally, we recommend using Atobarrier365 products, which contain skin lipid ingredients such as ceramides that help strengthen the skin barrier, especially for skin with a damaged barrier. However, since we cannot assess the precise condition of your irritated skin, we suggest testing the product on a small area before full application.

A. The skin barrier essentially functions as a 'wall.' Just like a wall separates and protects the interior from harmful external substances, the skin barrier separates and protects the inside of the skin from external threats. When the skin barrier is compromised, it becomes like a damaged wall, allowing harmful elements and irritants to into the skin while also resulting in the loss of internal moisture. This can lead to dryness and various other skin issues. Therefore, maintaining a strong skin barrier is the foundation of all skincare.

The skin barrier is composed of cells and lipids. The cells act like bricks, while the lipids act like cement. If the cement is not properly applied, the bricks can collapse. Similarly, in the skin barrier, lipids play a crucial role. These lipids consist of ceramides, cholesterol, and fatty acids, forming a layered lamellar structure. The Atobarrier365 line strengthens the skin barrier by using patented capsules that replicate the structure of skin lipids with these three key components, thereby reinforcing the skin barrier.
