Matrixyl
What do these badges mean?
Evidence tier
- AHuman-validated — Human trials showing positive results and good safety.
- BAnimal-grade — No human trials yet, but solid animal/preclinical evidence of effect and safety.
- CAnecdotal — No human or animal trials — only anecdotal/observational reports.
- DInsufficient evidence — No or insufficient evidence (encyclopedia only — never recommended by the builder).
Safety light
- 🟢 Green — Only mild, manageable side effects; reasonable safety data.
- 🟡 Yellow — Needs active management, has a meaningful contraindication/interaction, or has thin long-term data.
- 🔴 Red — Risk of a hospital-level event — treat with serious caution.
Browse-only — not on the protocol builder's curated shortlist, so the builder won't recommend it.
What is it?
Matrixyl is the flagship matrikine — a peptide fragment the skin reads as “collagen is breaking down, make more” — and one of the most widely formulated cosmetic peptides in the world, marketed in variants like Matrixyl 3000 and Matrixyl Synthe’6. It’s the anchor of the matrikine family alongside Syn-Coll, Rigin, Tripeptide-29, and Palmitoyl Dipeptide-6.
What does it do in my body?
Matrixyl is a matrikine that mimics collagen-breakdown fragments, signaling fibroblasts to increase synthesis of collagen I, III, IV, fibronectin, and hyaluronic acid — the “build the skin back up” mechanism, as opposed to the muscle-relaxant mechanism of the neuro-relaxer family.
How can it help me?
- Where the science stands: Moderate: 7 studies, 1 human — but the human study is off-target (radiation skin toxicity, not wrinkle efficacy); OHM’s 0035 grading cites formulator wrinkle RCTs not on the public profile
The full evidence — every human, animal, and lab study, graded — is one tap away: use the See the deeper science → toggle at the top.
Is it dangerous? What are the side effects?
The one on-profile human study (Röper et al., 2004) found no advantage over a comparison lotion in radiation-toxicity skin, with no notable adverse-effect signal reported. No dedicated adverse-effect data for cosmetic wrinkle-use was captured. Family-wide read: topical delivery carries a benign safety record.
Regulatory status: Cosmetic-grade OTC topical ingredient — not an FDA-reviewed drug.
Typical dosing
Talk to your medical provider before starting any protocol. That said, here are the doses most people commonly use — shared for educational purposes so you can have an informed conversation. These peptides are sold for research use only and are not FDA-approved drugs, and this isn't medical advice.
Topical-only. Typical cosmetic use: ~3–8% of the trade solution in leave-on products.
What should I avoid combining — and what's synergistic?
Matrixyl doesn't have a dedicated stacking protocol in our notes — the interactions that matter most are in the safety section above. For how people combine it with other peptides, the deeper-science view has the full detail.
How can I buy this?
We don't have a verified affiliate source for Matrixyl yet, so there's no coupon or vendor link here — we won't point you to a seller we haven't vetted. When buying any research-use-only peptide, the single biggest variable is the supply chain: insist on a vendor that publishes third-party Certificates of Analysis (COAs) confirming identity and >99% purity. Working with a peptide-literate clinician is one solid route — see our provider directory — or check back as our verified sources list grows.
The flagship matrikine and one of the most-formulated cosmetic peptides in the world — mechanism well characterized in vitro, but the one public human RCT on record is off-target (a radiation-toxicity study, not a wrinkle trial), and the strongest wrinkle data appears to be industry-held.

What the research shows
Public profile grade: Moderate — 7 studies, 1 human.
Important honesty note on the one human study: the single human RCT on the profile (Röper et al., 2004, Strahlenther Onkol, n=20, PMID 15127162) tested a Matrixyl-containing cream for radiation skin toxicity in breast-cancer patients and found no advantage over a comparison lotion — it is not a wrinkle-efficacy trial. The supporting collagen-stimulation data is (e.g. C16-KTTKS on fibroblasts, Jones et al., 2013, PMID 23320752).
OHM’s internal 0035 categorization pass grades Matrixyl Tier C / green / recommend-eligible, citing formulator wrinkle RCTs — “Robinson 2005, Trookman 2009” — that are not on the public peptidelist profile.
Honest status: the best-known matrikine; mechanism well characterized in vitro; the strongest wrinkle data is industry-held, and the one public human RCT is off-target.
