APPLICATION DIRECTION
A firmness brief should describe both the skin appearance you intend to evaluate and the texture consumers will use every day. This pathway includes individual peptides, the seven-peptide PxGHK-7® solution and a separate full-face microneedle format. Ingredient solutions and delivery-format projects require different development decisions.

PRODUCT CONCEPTS
Begin with
the finished format.
- Facial firming serum
- Age-care cream
- Full-face format development concept
These are examples for your brief. The supplied ingredient or format, its composition and target-market requirements are reviewed separately.
MAKE THE DECISION CLEAR
Three details
that shape the shortlist.
01
Separate material from format
Decide whether you are buying a cosmetic ingredient for your own base or developing a full-face delivery format. A soluble ingredient and a finished format are not interchangeable purchases.
02
Allow for colour and formula pH
PxGHK-7® is publicly described as a clear blue, water-soluble liquid with a published pH range of 6.0–6.5. Include colour and pH in your early formula review rather than treating the solution as visually neutral.
03
Specify the complete use experience
Record texture, dispensing pack and intended contact area. For a delivery format, add dimensions, application instructions and target-market classification to the brief.

Ingredient starting points.
Individual age-care candidates
Acetyl Tetrapeptide-2, Acetyl Tetrapeptide-11 and Copper Tripeptide-1 are existing catalogue matches for this pathway. Compare their precise identities and supplied grades against one defined product concept.
Complex or full-face format
PxGHK-7® and the Full-Face Microneedle Format represent two separate project routes: a supplied solution for formulation review, or a format brief. Their evidence and purchasing units must be assessed separately.
APPLICATION QUESTIONS
Before you
request the sample.
Is the full-face product an eye patch?
No. Full-face and eye-area formats concern different application areas. Specify the exact format, dimensions, instructions and documentation in the sample enquiry.
Why is PxGHK-7® blue?
The supplier describes a blue solution and lists Copper Tripeptide-1 in the active composition. Colour is a published product characteristic, not a purity or efficacy test.
Can both Dipeptide-4 records be treated as one ingredient?
No. The catalogue preserves two distinct source CAS identities: 24587-41-5 and 19246-18-5. Use the exact identity in your enquiry.
