- Acetyl octapeptide-3 is an eight-amino-acid peptide.
- It targets the look of deeper expression lines.
- It's often paired with acetyl hexapeptide-8 for broader coverage.
What it is
Acetyl octapeptide-3 is a peptide made of eight amino acids. It's closely related to acetyl hexapeptide-8, with two extra amino acids in its chain.
What it's used for
Formulators use it to target the look of deeper expression lines: the lines between the brows, across the forehead and around the eyes that have become more set over time.
Why pair it with other peptides
Expression lines come from repeated movement, but their depth also depends on how firm and hydrated your skin looks. That's why DOSE combines acetyl octapeptide-3 with firming peptides and 2% GHK-Cu, so one serum covers movement, firmness and renewal together.
Tips for best results
- Use it twice a day, every day.
- Wear SPF every morning; sun exposure makes lines look deeper.
- Keep skin well moisturised; dehydration makes fine lines more visible.
FAQ
What's the difference between acetyl octapeptide-3 and acetyl hexapeptide-8?

Is acetyl octapeptide-3 safe for sensitive skin?
It's generally well tolerated. As with any new product, patch test first.
Where should I apply it?
Across your whole face, with a little extra attention on the forehead, between the brows and around the eyes.
