What Happens to Our Skin as We Age?

Healthy skin is supported by an organized network of collagen, elastin and other molecules within the dermis. This network is known as the extracellular matrix, and it gives the skin much of its strength, flexibility and structure.

Specialized cells called fibroblasts help maintain this network by producing collagen, elastin, fibronectin and hyaluronic acid. These substances work together to keep the skin firm, resilient and well hydrated.

As we age, several natural changes occur:

Fibroblasts become less active and responsive.

The production of new collagen gradually slows.

Existing collagen fibers become fragmented and less organized.

The skin becomes less efficient at retaining moisture.

Environmental stress—especially cumulative ultraviolet exposure—can accelerate the breakdown of the skin’s supporting structure.

Over time, the skin’s repair processes may no longer keep pace with this gradual breakdown. The result can be the visible development of fine lines, wrinkles, dryness, reduced elasticity and loss of firmness.

In simple terms

Younger skin continually produces and organizes the materials that keep it firm and smooth. With age, the skin produces less of this structural support while existing collagen is broken down more quickly.

Formulation Science

The Science Behind Sensophore

All products in the Sensophore skincare line contain Matrixylâ„¢ 3000. Matrixylâ„¢ 3000 is a peptide complex made from two messenger peptides:

01

Palmitoyl
Tripeptide-1

Messenger Peptide

02

Palmitoyl
Tetrapeptide-7

Messenger Peptide

Complementary Peptide

These peptides have complementary roles and belong to a group of biological messengers known as matrikines. Matrikines are small protein fragments that can act as signals to tell the skin additional support is needed when structural proteins such as collagen are naturally broken down.

Two complementary actions

Together, the peptides help address visible skin aging from two directions:

Palmitoyl Tripeptide-1: Supporting renewal

Palmitoyl Tripeptide-1 is designed to imitate a naturally occurring collagen fragment. It helps signal fibroblasts to support the production of components associated with the skin’s structural framework, including collagen, fibronectin and hyaluronic acid.

This can help the skin appear:

  • Firmer
  • Smoother
  • More resilient
  • Better hydrated

Palmitoyl Tetrapeptide-7

Supporting a balanced skin environment

Palmitoyl Tetrapeptide-7 regulates inflammatory pathways. Persistent, low-level inflammation can contribute to the accelerated breakdown of collagen and other supporting components of the skin.
By reducing inflammatory signaling, Palmitoyl Tetrapeptide-7 prevents breakdown of existing collagen. 

  • skin aging from two directions

    • Supporting the production and maintenance of structural components
    • Helping reduce conditions associated with their accelerated breakdown

  • Using Sensophore Skincare 

    Sensophore products have been formulated to be used morning and evening to provide consistent support as clinical evaluations of Matrixyl™ 3000 have shown improvements in wrinkles, elasticity, and skin structure with twice daily use. 


    Consistency matters more than applying excessive amounts. Peptide signaling and changes in the skin’s supporting structure occur gradually.

Expected Results 

Matrixylâ„¢ 3000 is designed to provide cumulative benefits rather than an immediate resurfacing effect. With regular use, you may begin to notice:
