Compare Palmitoyl Tripeptide-1 (Pal-GHK) with other peptides →Summary
A skin cream helper that builds collagen and heals skin.
- Typical dose
- 2-5% concentration 1-2x daily
- Route
- Topical
- Cycle length
- Ongoing
- Evidence
- Limited human data
Mechanism
How it works
Pal-GHK acts like a construction foreman for your skin — it tells fibroblasts to build more collagen and fill in gaps.
Palmitoyl tripeptide-1 mimics a fragment of laminin α1 chain, signaling fibroblasts to produce collagen, fibronectin, and hyaluronic acid.

In depth
Full profile
What it does
Firmer skin, fewer wrinkles, and cuts that heal faster.
How it works
Pal-GHK is like a building boss for your skin. It tells your skin cells to make more collagen and fill in gaps.
It slips through the top layer of your skin. Then it grabs onto skin cells and tells them what to do.
What to expect
You can see your skin look better in 4-8 weeks.
- Weeks 2-4: Your skin feels smoother.
- Weeks 4-8: Tiny lines start to fade.
- Weeks 8-12: Skin feels firmer and more bouncy.
Good to know
- Test a small patch of skin first
- Use a moisturizer with it
Staying safe
- Almost none; your skin handles it very well
- A little redness (this is rare)
Avoid if you have:
- People whose skin reacts badly to peptides
Mechanism of action
Palmitoyl tripeptide-1 mimics a fragment of laminin α1 chain, signaling fibroblasts to produce collagen, fibronectin, and hyaluronic acid.
Penetrates stratum corneum due to palmitoyl group, binds to integrin receptors on fibroblasts.
Pharmacodynamics
Visible improvements at 4-8 weeks.
Firmer skin, reduced wrinkling, faster wound closure.
Timeline
- Weeks 2-4: Improved skin texture.
- Weeks 4-8: Reduced fine lines.
- Weeks 8-12: Firmer, more elastic skin.

- Contact dermatitis
Contraindications & risk mitigation
Contraindicated in:

Qué hace
Piel más firme, menos arrugas y cortes que sanan más rápido.
Cómo funciona
Pal-GHK es como un jefe de obra para tu piel. Le dice a tus células cutáneas que produzcan más colágeno y rellenen los espacios.
Se filtra a través de la capa superior de tu piel. Luego se une a las células cutáneas y les indica qué hacer.
Qué esperar
Puedes notar una mejora en tu piel en 4-8 semanas.
- Semanas 2-4: Tu piel se siente más suave.
- Semanas 4-8: Las líneas finas comienzan a desvanecerse.
- Semanas 8-12: La piel se siente más firme y elástica.
Bueno saber
- Prueba una pequeña zona de la piel primero
- Usa una crema hidratante con él
Manteniéndose seguro
- Casi ninguna; tu piel lo tolera muy bien
- Un poco de enrojecimiento (esto es raro)
Evitar si tienes:
- Personas cuya piel reacciona mal a los péptidos
Mecanismo de acción
El palmitoyl tripeptide-1 imita un fragmento de la cadena α1 de la laminina, señalando a los fibroblastos para que produzcan colágeno, fibronectina y ácido hialurónico.
Penetra el estrato córneo gracias al grupo palmitoil y se une a los receptores de integrina en los fibroblastos.
Farmacodinamia
Mejoras visibles a las 4-8 semanas.
Piel más firme, menor formación de arrugas y cierre más rápido de heridas.
Cronología
- Semanas 2-4: Mejora de la textura de la piel.
- Semanas 4-8: Reducción de líneas finas.
- Semanas 8-12: Piel más firme y elástica.

FAQ
Common questions
Is Pal-GHK the same as Matrixyl?
Similar but different peptide. Matrixyl is palmitoyl pentapeptide-4; Pal-GHK is palmitoyl tripeptide-1. They work well together.
Can I use it with copper peptides?
Yes, but use separately (AM/PM) as copper can oxidize other peptides.
What is the evidence level?
This compound is classified as Limited human data. Some human data exists but trials are small, short-term, or not yet replicated.
