Matrixyl and Argireline are two of the best-known peptides in skincare, and they often get lumped together as "anti-ageing peptides". But they're used for different kinds of lines. Argireline is the go-to for the look of expression lines, while Matrixyl is used for overall smoothness and the look of firmer skin. Here's a plain-English comparison of which peptide suits which lines, how to use them together or with GHK-Cu and SNAP-8, where they fit morning and night, and how to keep it to one simple routine when you're busy or travelling.
What is Matrixyl?
Matrixyl is the trade name for palmitoyl pentapeptide-4 (also called Pal-KTTKS). It's a five-amino-acid peptide with a fatty "tail" attached, which helps it blend into skincare formulas. It's often described as a "signal peptide" and is used in serums, eye creams and night creams for skin that looks smoother, firmer and more even. Don't confuse it with Matrixyl 3000, which is a different blend of two peptides. Read our full Matrixyl guide.
What is Argireline?
Argireline is the trade name for acetyl hexapeptide-8 (you may also see it listed as acetyl hexapeptide-3). It's a water-soluble six-amino-acid peptide used for the look of expression lines, the ones that show up where your face moves most, like the forehead, between the brows and around the eyes. It helps skin in those areas look smoother. Read our full Argireline guide.
Which peptide for which lines?
- Forehead lines and frown lines: these are expression lines, so Argireline is the natural first pick for helping them look softer.
- Crow's feet: also expression lines, so Argireline suits them well. Matrixyl in an eye-area product can help the surrounding skin look smoother too. Keep both on the outer corner and brow bone, well away from the eye itself. See our eye area guide.
- Fine lines across the cheeks and overall texture: Matrixyl is the better fit here, for skin that looks smoother and more even all over.
- Skin that's starting to look less firm: Matrixyl, for the look of firmer, bouncier skin.
- A bit of everything: use both. They do different jobs, so they complement each other rather than doubling up.
How they differ
- Focus: Argireline targets the look of expression lines; Matrixyl targets overall smoothness and the look of firmness.
- Structure: Argireline is a water-soluble acetylated peptide. Matrixyl has a palmitic acid tail, so it dissolves better in glycols than in plain water.
- Use level: Matrixyl is used at tiny levels, measured in parts per million. Argireline is used at higher levels. Retail labels often quote percentages of dilute trade solutions, so you can't compare percentages across brands directly.
- Feel and tolerance: both are lightweight and generally well tolerated by most skin types. Neither is an acid or exfoliant, so neither should tingle.
- How long to judge: give either one at least 6–8 weeks of consistent use. Matrixyl studies typically looked at 8–12 weeks. Individual results vary.
How to choose
- Your main concern is lines that show when you smile, frown or raise your brows: start with Argireline.
- Your main concern is texture, fine lines at rest or skin that looks less firm: start with Matrixyl.
- You want one peptide to start with and aren't sure: pick the concern that bothers you most in the mirror and start there. You can add the other later.
- You already use Argireline and want a step up for expression lines: try SNAP-8 instead. See Argireline vs SNAP-8.

Can you use Matrixyl and Argireline together?
Yes. They're compatible and they cover different concerns, which is why they're one of the most common peptide pairings. You can layer them in the same routine (thinnest, most watery serum first, wait a minute, then the next) or split them between morning and night. Splitting them is the simplest option and keeps each step to one product.
Using them with GHK-Cu or SNAP-8
- With GHK-Cu: GHK-Cu is used for firmer-, smoother- and more radiant-looking skin overall. It pairs well with either peptide. A common routine is Argireline or Matrixyl in the morning and GHK-Cu at night. See our GHK-Cu guide.
- With SNAP-8: SNAP-8 does a similar job to Argireline, so you don't need both. If you use SNAP-8 for expression lines, Matrixyl still adds something different. Read our SNAP-8 guide.
- Keep it sensible: two or three peptides in a routine is plenty. More products don't mean better-looking results, and a simpler routine is easier to stick with.
AM/PM placement
Morning
- Gentle cleanse or splash with water.
- 2–3 drops of Argireline serum on the forehead, between the brows and the outer eye area.
- Moisturiser if needed, then SPF 50+ sunscreen.
Night
- Cleanse to remove sunscreen and the day.
- Matrixyl serum over the whole face, or GHK-Cu serum or cream.
- Moisturiser on drier areas.
You can swap them around (Matrixyl in the morning, Argireline at night) if that suits you better. Both are fine under sunscreen. For the full layering order with other actives, see our AM/PM peptide routine.
Busy life or on the road: keep it to one routine
If you're juggling work and kids, or living out of a suitcase, you don't need a shelf of products. Pick the one peptide that matches your main concern and use it every day: Argireline in the morning before sunscreen, or Matrixyl at night. Our serums have a hyaluronic acid base, so the same small bottle gives you hydration too. One bottle in the toiletry bag, two minutes a day, done. Add the second peptide when you're home and have time. Our travel skincare guide has more carry-on tips.
Patch test first
Before your first full use, apply a small amount to your inner forearm or behind your ear once a day for 2–3 days. Stop and wash it off if you get redness, itching, stinging or swelling. Don't apply to broken, sunburnt or irritated skin, and keep products out of your eyes. If you're pregnant or breastfeeding, or have a skin condition, ask a pharmacist or health professional first. Our patch testing guide has more detail.
FAQ
Is Matrixyl or Argireline better for wrinkles?
It depends on the lines. Argireline is used for the look of expression lines like forehead lines, frown lines and crow's feet. Matrixyl is used for fine lines at rest, overall smoothness and the look of firmer skin.
Can I use Matrixyl and Argireline together?
Yes. They're compatible and do different jobs. Layer them, or use one in the morning and the other at night.
Which should I start with?
Start with the one that matches the concern you notice most. Argireline for lines that show when your face moves; Matrixyl for texture and the look of firmness.
Is Matrixyl the same as Matrixyl 3000?
No. Matrixyl is palmitoyl pentapeptide-4. Matrixyl 3000 is a blend of palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7.
Can I use them with GHK-Cu?
Yes. A simple routine is Argireline or Matrixyl in the morning under sunscreen and GHK-Cu at night.
How long before I see a difference?
Use your serum consistently once or twice a day for at least 6–8 weeks. Individual results vary.
