After washing BELLOCEA™ off the face, it will gradually break down into cellulose, a natural material and acetic acid, a food ingredient, through the action of water in the natural environment. Therefore, cellulose acetate is said to be a material with low environmental impact.

Safety assessment

BELLOCEA™ is composed of fine spherical particles of cellulose acetate, which is made from natural cellulose and acetic acid, the main component of vinegar, and is a substance which is highly safe for living organisms.
