The Science
Peptide technology,
decoded.
A deep dive into the bioactive compounds at the heart of every Pept formula.
What Are Peptides?
Peptides are short chains of amino acids, the fundamental building blocks of all proteins in the human body. They occur naturally, acting as biological messengers that tell cells and tissues how to behave. Because of their small molecular size, peptides interact with specific receptors with extraordinary precision, making them one of the most targeted compounds in modern biochemistry.
How Peptides Work
Unlike broad-spectrum compounds, each peptide class has a specific biological target. Some stimulate the pituitary gland to influence growth hormone release. Others act on receptors in connective tissue. Some influence gene expression related to ageing and cellular longevity. This specificity is what makes peptides a significant area of research interest.
Triple Independent Testing, Our Standard
At Pept, quality is a documented process rather than a marketing claim. Every product we sell is independently tested by three separate accredited laboratories before it reaches you. Each lab analyses purity, potency and the absence of contaminants independently of the others. We require all three sets of results to meet our specifications before a batch is approved for sale. Certificates of Analysis are available for every product so you can review the data yourself.
Research Use
All peptides sold by Pept are intended for research purposes only. See our Research Use Only policy for full details.
What Are Peptides?
The building blocks of skin performance
Peptides are short chains of amino acids — the fundamental units that make up proteins like collagen, elastin, and keratin. In the context of skincare, bioactive peptides act as signalling molecules, communicating with skin cells to trigger specific biological responses.
As we age, our natural peptide signalling diminishes. Collagen production slows. Skin barrier function weakens. Recovery from environmental stress takes longer. Pept's formulations work by replenishing and amplifying these peptide signals, giving skin the biological instructions it needs to perform.

Our signature ingredient complex
Research Notes
How our key peptides work
Active
Matrixyl 3000
A clinically-studied peptide complex shown to stimulate collagen synthesis and reduce the depth of wrinkles. Works by mimicking the activity of fragmented collagen to trigger fibroblast repair responses.
Active
Copper Peptide GHK-Cu
One of the most extensively researched skincare actives. GHK-Cu promotes wound healing, stimulates collagen production, and possesses potent antioxidant properties.
Active
Acetyl Hexapeptide-3
Works by inhibiting the neurotransmitter signals that cause facial muscle contractions — a topical approach to reducing expression lines without injectables.
Active
Hyaluronic Acid Complex
A multi-weight HA system delivering surface hydration, mid-dermal plumping, and deep dermal moisture retention — all in a single serum.
