Acetyl Tetrapeptide-3
Also known as: Acetyl Tetrapeptide
What It Is
A synthetic tetrapeptide designed to strengthen the dermal-follicular junction — the connection between the hair follicle and the surrounding dermal tissue.
What It Does
Supports the anchoring environment of hair follicles and works synergistically with other scalp peptides to promote a healthier follicle matrix.
Best For
Benefits
- Targets the structural proteins at the dermal-follicular junction
- Works synergistically with Biotinoyl Tripeptide-1
- Supports the matrix environment that supports follicle health
When to Be Careful
- Requires consistent, long-term use
- Part of a multi-ingredient approach — not a standalone solution
Used alongside Biotinoyl Tripeptide-1 in advanced hair density formulas, Acetyl Tetrapeptide-3 represents the clinical sophistication of modern scalp serums beyond standard biotin or caffeine.
Often lumped into "generic peptide" thinking. This peptide has a specific mechanism targeting the structural support at the follicle base — it is not a broad-spectrum anti-aging peptide.
Part of a leave-in scalp serum. Applied daily to clean, dry scalp.
People using dedicated scalp serums with a hair density focus.
Generally well tolerated at standard concentrations.
