INCI: Tetrapeptide-21

Protein tetrapeptide-21

Peptides are small proteins that have many functions in nature. For example, as transmitters in plants or as hormones in the human body. These protein building blocks trigger cellular metabolism as signal substances. This means increased collagen synthesis, better regeneration and formation of skin cells.

Peptides therefore play an important role in the development of “anti-aging” cosmetics. Their degradation products, amino acids, are also at the forefront of skin care.

Tetrapeptide-21 MB is a new bioactive tetrapeptide that is able to significantly increase the activity of collagen fibers. Tetrapeptide-21 MB minimizes the appearance of wrinkles and reduces skin roughness.
