A peptide your skin already makes — just less of it with age
Post-blemish marks, fine lines, uneven tone — one serum, one active, one habit.
Uneven-looking tone. Marks left behind after blemishes. Early fine lines starting to show. They tend to show up together — and they all come down to how smooth and even skin looks over time. GHK-Cu (Copper Tripeptide-1) helps visibly smooth texture and improve the look of tone with consistent use. Asterwood's Copper Peptides Serum keeps the formula to 6 ingredients — including 1.50% Hyaluronic Acid — so the active has nothing in its way. Patch test first, especially on sensitive skin. Then make it your daily step.*

Why copper peptides?
Breakouts fade. The marks they leave behind take longer. Meet GHK-Cu.
Breakouts clear up. The marks they leave behind take longer. GHK-Cu — Copper Tripeptide-1 — helps visibly smooth texture, even out the look of tone after blemishes, and promote healthier-looking skin over time. Asterwood's Copper Peptides Serum delivers it in a 6-ingredient formula with 1.50% Hyaluronic Acid for continuous hydration. No fragrance. No silicones. No unnecessary anything. Just one well-studied peptide — applied daily, after cleansing, before moisturizer.*
Your skin isn't broken
It just makes less of the peptide over time — the same way hydration and bounce naturally change with age.
50+ years of research
GHK-Cu is one of the most-studied peptides in skin science, researched for over half a century.
Put it back in
Asterwood gives you clinically-studied GHK-Cu at an active concentration — in a clean, 6-ingredient Hyaluronic Acid base. The blue-green color is the GHK-Cu being active.*
What it does for your skin
Uneven texture, post-blemish marks, early fine lines. One serum for the look of all three.
Rough spots, enlarged-looking pores, an uneven surface — texture can be one of the slowest things to change. GHK-Cu is studied for its role in smoother, more refined-looking skin, which is why it's the hero of this formula. Asterwood's Copper Peptides Serum delivers it alongside 1.50% Hyaluronic Acid, so skin stays hydrated while the peptide works. Fragrance-free. Absorbs fast. Apply 2 to 3 drops to clean, dry skin, morning or night. A more refined-looking texture typically starts showing around weeks 3 to 4 of consistent use.*
Firmer-Looking Skin
Helps visibly improve the appearance of firmness and elasticity with consistent use — skin that looks more resilient and bounced-back.*
Refined Texture
Supports a visibly smoother, more even skin surface and softens the look of fine lines over time.*
Plump, Quenched Skin
1.50% Hyaluronic Acid — a natural polysaccharide that draws and holds moisture — for immediate, lasting hydration and a supple, plumped finish.
What to expect, week by week
Fine lines and post-blemish marks have one thing in common: GHK-Cu helps with the look of both.
Fine lines are easier to soften while they're still fine. GHK-Cu — Copper Tripeptide-1 — is one of the most studied actives for supporting the look of firmer skin and softer-looking fine lines with consistent use. Asterwood's Copper Peptides Serum applies in seconds (2 to 3 drops, pressed into clean skin), absorbs fully with no residue, and texture typically starts looking smoother within 3 to 4 weeks. By weeks 6 to 8, firmer-looking skin and softer-looking fine lines become more noticeable. Six ingredients. Zero friction. Start your routine today.*

Proven ingredients

Uneven-looking tone — from sun, past blemishes, or general dullness — changes with consistent use of the right active over time. GHK-Cu (Copper Tripeptide-1) helps promote a visibly smoother, more even-looking surface. Asterwood's Copper Peptides Serum pairs it with 1.50% Hyaluronic Acid for hydration that holds through the day. Six ingredients. No fragrance. No silicones. Use it daily and give it time.*
GHK-CU 0.10%
Copper Tripeptide-1
The hero active. GHK is a tripeptide — three amino acids — that binds with copper to become GHK-Cu, the copper peptide your skin naturally contains. Studied for over 50 years and prized for supporting the look of firmer, smoother skin. Its natural blue-green hue is what gives the serum its color.*
Sodium Hyaluronate · 1.50%
Hyaluronic Acid
A natural polysaccharide that retains moisture in the body — it draws hydration into skin for a plumper, more supple appearance, and helps every active absorb better.
The Clean Base
Water · Pentylene Glycol · Phenylpropanol · Sodium Hydroxide
A minimalist carrier, a humectant, a gentle preservative, and a touch of pH balancer. No filler. Nothing that doesn't earn its place.

Before you buy
Questions, answered
GHK-Cu (Copper Tripeptide-1) is a small copper-bound peptide and one of the most extensively studied actives in dermatology. In skincare it's valued for supporting the look of firmer, smoother, more refined skin. Our serum uses it at 0.10%, paired with 1.50% Hyaluronic Acid.*
It does — GHK-Cu is a copper-bound peptide your body produces naturally, with the highest levels when you're young. Like hydration and bounce, your natural supply tends to taper with age. That's the thinking behind topping it back up topically with an active-level formula. The peptide has been studied for over 50 years.*
That color isn't a dye — it's the copper peptide itself. The natural blue-green hue is a built-in sign that the GHK-Cu in the bottle is present and active. We never add synthetic colorants.
Skin feels hydrated and smooth from day one. Most people notice improved softness within 1–2 weeks, a more refined surface around 3–4 weeks, and visibly improved firmness and softer-looking fine lines around 6–8 weeks of consistent daily use. Individual results may vary.*
Yes — it layers cleanly over Hyaluronic Acid and under moisturizer, morning or night. Keep strong exfoliating acids (AHA/BHA) and high-dose Vitamin C to a separate step or routine so nothing competes.
It's fragrance-free, silicone-free, and built on just six ingredients, which many people with sensitive skin appreciate. As with any new active, patch test on your neck first — especially if you have known copper sensitivity. For external use only; avoid the eye area.
No parabens, sulfates, phthalates, dyes, or synthetic fragrance. Vegan and never tested on animals. Developed by chemists, third-party tested, and made in the USA of domestic and globally sourced ingredients.*
