Our peptide range brings together selected cosmetic peptide ingredients chosen for their role in modern formulation. These are the specialist actives at the heart of our range — ingredients intended to support specific formulation goals when used appropriately and in accordance with their technical documentation.
Peptides are not a shortcut, a guaranteed result, or a substitute for responsible formulation. Their performance depends on factors including concentration, stability, compatibility, pH, preservation, packaging, and the finished product in which they are used.
Copper Tripeptide-1 (GHK-Cu)
Copper Tripeptide-1 (also known as GHK-Cu) is a copper-containing tripeptide used in cosmetic formulation. It is commonly selected for formulations focused on skin conditioning and the appearance of skin quality. As with all peptide ingredients, the supplied material must be handled and incorporated according to its specification. It should not be confused with a finished cosmetic product or presented as a guaranteed treatment.
Palmitoyl Pentapeptide-4 and Related Peptides
Palmitoyl pentapeptide-4 (and related matrix-supporting peptides such as those found in certain commercial complexes) are commonly used in cosmetic formulations designed to support the appearance of smoother-looking, more conditioned skin. Raw materials should be used only within the supplier’s recommended parameters and with appropriate attention to formulation stability. Products should always be identified by their exact INCI name, supplier specification, and authorised description.
Acetyl Hexapeptide-8
Acetyl hexapeptide-8 is a synthetic hexapeptide commonly used in cosmetic formulations focused on the appearance of expression lines and skin smoothness. Any product description should reflect the exact material supplied, its documentation, and the claims that can be appropriately substantiated for the finished formulation.
Copper Tripeptide-3 (AHK-Cu)
Copper tripeptide-3 (AHK-Cu) is a copper peptide associated with scalp and hair-focused formulation concepts. It is kept separate from our face-focused peptide range because its intended formulation direction is different. Copper tripeptide-3 is not included in our facial house blend.
Other Specialist Peptides
Our peptide range may develop over time as we assess additional materials and their documentation. Any new peptide will be presented with its exact identity, intended cosmetic use, handling requirements, and relevant supplier information.We do not describe a peptide by broad promises alone. We aim to provide the information needed to understand what the ingredient is, what it may be used for, and what must be considered before formulation.
The Raw+Pour House Blend
A considered combination of our facial peptide ingredients The Raw+Pour House Blend is our planned combination of selected face-focused peptide ingredients in one formulation concept. It is designed to bring together the facial peptides in our range for customers who want to explore a multi-peptide approach rather than working with each ingredient separately. Copper tripeptide-3 (AHK-Cu) is not included because it is intended for scalp and hair-focused applications rather than facial formulation. The House Blend is not intended to suggest that combining ingredients automatically makes them more effective. A multi-peptide formulation requires careful consideration of:
- Ingredient identity and purity
- Recommended use levels
- Solubility and dispersion
- pH compatibility
- Stability and degradation
- Preservative compatibility
- Packaging and storage
- Potential interactions between ingredients
- The intended use of the finished formulation
The final composition, specifications, directions, and permitted claims for the House Blend will depend on the exact ingredients used, their supplier documentation, and the applicable requirements for the product’s intended market.
For the Curious, the Careful and the Independent
Raw+Pour is designed around the individual customer. Whether you’re learning about cosmetic ingredients, developing your formulation knowledge, or experimenting with small-scale skincare projects, we want to make specialist raw materials more accessible without requiring industrial-sized purchases. Our focus is on home formulators, skincare enthusiasts, and independent makers working on a personal scale — people who value understanding their ingredients rather than simply buying another finished product.
A Considered Approach to Skincare
We believe that informed choices start with good information. That means being clear about what an ingredient is, the form in which it is supplied, and the information available to help customers assess its suitability for a particular formulation.
We aim to provide relevant product specifications and handling information where available, with an emphasis on transparency, responsible sourcing, and realistic descriptions of each ingredient.
We don’t believe in exaggerated promises. We believe in giving people the information they need to explore ingredients thoughtfully.
Your ingredients. Your learning. Your formulation.
Raw+Pour is here for people who want to understand skincare at ingredient level — one material, one formulation, and one considered choice at a time.

Important Product Information
Raw materials are supplied as ingredients, not as finished cosmetic products. Suitability, concentration, compatibility, stability, and safe use must be assessed for the intended application. Not every ingredient is suitable for every skin type or formulation. Please consult the relevant product documentation and applicable safety guidance before use.
Peptide names, trade names, and ingredient descriptions must be checked against the exact material supplied and its current technical documentation. Any finished cosmetic product or House Blend must be assessed, labelled, and marketed in accordance with applicable requirements before sale.
