Qu’est-ce-que "l'Acetyl Tetrapeptide-11" et quelle est son utilité ?

What is "Acetyl Tetrapeptide-11" and what is its use?

Time leaves its mark on the skin. As we age, wrinkles gradually deepen and the skin begins to sag. While this process is inevitable, there are treatments available that can slow it down. To this end, "Acetyl Tetrapeptide-11" is one of the ingredients used in serums and creams to combat skin ageing. Here is everything you need to know about this ingredient and its usefulness.

Acetyl Tetrapeptide-11: Definition and Role.

Theacetyl tetrapeptide-11 is the reaction product of acetic acid and tetrapeptide-11. It belongs to the family of peptides, proteins naturally present in the body. Indeed, when amino acids assemble, they form chains known as peptides. Once formed, these chains develop different types of proteins such as keratin, collagen, and elastin. Peptides thus constitute the foundations of the skin and are responsible for its resilience, texture, and strength. Without them, the skin would age prematurely: visible and pronounced wrinkles, texture changes, and loss of firmness.

Acetyl Tetrapeptide-11 is a signal peptide that stimulates the proliferation of keratinocytes. Its role is to increase cell density, while accelerating skin regeneration. Thanks to its properties, the skin gains volume and the appearance of fine lines is diminished. To achieve this, this molecule acts on a protein present on the skin's surface, smoothing its texture. Thus, due to its action, Acetyl Tetrapeptide-11 is an indispensable ingredient in many treatments combating the signs of ageing.

Acetyl Tetrapeptide-11, a skincare treatment.

Among our skincare products, our redensifying serum is designed to combat skin sagging. In addition to acetyl tetrapeptide-11, it is composed of two other active ingredients, namely the cyclopeptide-5 and theacetyl tetrapeptide-9. These three ingredients simultaneously target different aspects involved in skin density and support.

The three-peptide complex is to be used in the morning and evening. To do this, apply 2 to 3 drops to the face after it has been thoroughly dried and cleaned. To allow the treatment to penetrate the skin, you can gently massage it in circular motions. Once this process is completed, proceed to the application of your daily moisturising cream .
