Reported patent results
Reported findings
Particle-size, loading and storage observations support a delivery-system claim, without a human efficacy experiment.
Formulation experiments with lipid/wax particles carrying palmitoylated cosmetic peptides, including Pal-GHK.
| Measure | Result | Comparison, timing and statistics |
|---|---|---|
| Particle size | Suitable surfactant preparations described as D50 <0.6 µm | A formulation acceptance result, not skin penetration or a clinical endpoint |
| Pal-GHK co-encapsulation | Pal-GHK and Pal-GQPR mixture reported as stably encapsulated over time | The individual numerical storage table was not transcribed |
| Different-peptide experiment | Approximately 82% adsorption reported for Pal-KTFK | This is not a Pal-GHK result and is not transferred to GHK |
Several experiments use other peptides. Particle properties and stability do not demonstrate human anti-aging benefit or GHK-Cu efficacy.

Methods, limitations & source review
Study limitations
- Delivery performance is distinct from clinical efficacy of the ingredient or finished cosmetic.
- Several experiments use other peptides. Particle properties and stability do not demonstrate human anti-aging benefit or GHK-Cu efficacy.
- Patents record claimed inventions and supporting disclosures. Publication or grant does not establish clinical efficacy, safety or marketing approval. Members of one patent family and related journal reports can describe the same experiments.
- Status labels are Google Patents index snapshots for the displayed publication or application; the record gives its source-check date. Official registers and every national family member have not been independently checked. These labels do not establish freedom to operate.
Publication counts are not counts of independent trials. Reviews, translations and reports sharing participants may overlap. Findings apply to the studied preparation, population and endpoints.
Document format: Original patent text and indexed metadata
Review depth: Claims, selected reported findings and limitations reviewed; supporting experiments not comprehensively appraised.
Related-report group: patent-family-87889138. Reports in this group are not assumed to be independent trials.
Source access and review scope
Original patent publication accessed through Google Patents. Claims, selected reported findings and source limitations checked. The results section identifies the examples, tables and any numerical extraction gaps. No complete experimental audit, prosecution review or legal claim construction was performed.
Recorded source-check date: 2026-11-06. This date does not imply a completed systematic review.
