Peptide guide
Our Peptides
Softer-looking lines. Firmer-looking skin. Fuller-looking hair.
Every Biolabs formula is built around copper peptides and multi-peptide blends. This page shows which peptide sits in which product, what that peptide is for, and where each product fits in a routine, so you can match a cream, serum or hair step to what you want to see in the mirror.
Three names to know: GHK-Cu (Copper Tripeptide-1), SNAP-8 (Acetyl Octapeptide-3) and AHK-Cu (copper tripeptide-3).
Copper Tripeptide-1
GHK-Cu
The blue drop for firmer-looking skin.
Studied for: supporting collagen and elastin, firmness, skin thickness and fine lines over 12 weeks, plus antioxidant and calming activity.
GHK-Cu is the copper peptide behind the clear-blue tint in our face serums and creams. It supports the look of firmer, smoother skin, with fewer visible fine lines and a more even texture. Percentages are peptide powder by weight: 2% in Intensive Serum is our highest face strength; 1% sits in Smooth Line Serum, Renewal Cream, Daily Copper Cream and Firming Body Lotion.

Acetyl Octapeptide-3
SNAP-8
Big expressions. Softer-looking lines.
Studied for: smoothing the look of expression lines and dynamic wrinkles around the forehead and eyes, visible in 3–4 weeks.
SNAP-8 sits with GHK-Cu in Smooth Line Serum and Renewal Cream only. Smooth Line also carries Acetyl Hexapeptide-8 (Argireline), Palmitoyl Pentapeptide-4 and Palmitoyl Tripeptide-1. SNAP-8 is not in Intensive Serum, Daily Copper Cream, Firming Body Lotion, Renewal Sheet Masks, or any hair product.

Hair & scalp
AHK-Cu (copper tripeptide-3)
Fuller-looking hair starts at the roots.
AHK-Cu (copper tripeptide-3) is the copper peptide in our hair and scalp formulas. It is for fuller-looking hair at the roots and a scalp that feels hydrated and comfortable. Hair & Scalp Serum and Scalp Boost Spray each carry 1% AHK-Cu (copper tripeptide-3). Strength Shampoo and Strength Conditioner pair it with GHK-Cu: Two copper peptides. One glossy finish.

Peptide FAQs
What does GHK-Cu do?
GHK-Cu is our blue copper peptide for firmer-looking skin. Studied for: supporting collagen and elastin, firmness, skin thickness and fine lines over 12 weeks, plus antioxidant and calming activity. You’ll find it at 2% in Intensive Serum and at 1% in Smooth Line Serum, Renewal Cream, Daily Copper Cream and Firming Body Lotion.
What does SNAP-8 do?
SNAP-8 is for softer-looking expression lines: big expressions, softer-looking lines. Studied for: smoothing the look of expression lines and dynamic wrinkles around the forehead and eyes, visible in 3–4 weeks. In our range it sits with GHK-Cu in Smooth Line Serum and Renewal Cream only.
Which serum should I choose?
Choose Intensive Serum for our highest-strength GHK-Cu (2%) and firmer-looking skin. There is no SNAP-8 in that bottle. Choose Smooth Line Serum for GHK-Cu 1% plus SNAP-8 0.1% (and Argireline) when you want softer-looking expression lines. Both go on after cleansing, before cream, morning and night.
Can I use serum and cream together?
Yes. Serum first, then cream, morning and night. Face Pair = Smooth Line + Renewal (SNAP-8 in both). Skincare Set = Intensive + Renewal (SNAP-8 in the cream only). Serum + Face Cream Pair = Intensive + fragrance-free Daily Copper Cream (no SNAP-8).
Which product should I start with?
Start with the concern you most want to see a difference in. Expression lines: Smooth Line Serum. Firmness and texture: Intensive Serum. Want a cream step: Renewal Cream. Fuller-looking hair: Hair & Scalp Serum. Body: Firming Body Lotion. Each one has a matching set in the “Shop by concern” section above.
Which products are for hair?
Hair & Scalp Serum and Scalp Boost Spray: both 1% AHK-Cu (copper tripeptide-3), leave-in. Wash day: Strength Shampoo and Strength Conditioner (GHK-Cu + AHK-Cu (copper tripeptide-3)), also as the Hair Set.
What’s the difference between GHK-Cu and AHK-Cu (copper tripeptide-3)?
Both are copper-bound tripeptides. GHK-Cu (Copper Tripeptide-1) is in our face and body care for firmer-looking skin. AHK-Cu (copper tripeptide-3) is in our hair and scalp care for fuller-looking hair at the roots. Strength Shampoo and Conditioner use both.
