Amplified Glow GHK-Cu + SNAP-8 Peptide Renewal Serum Review
This is the best-documented serum in the Amplified Glow range. It is the only skincare product in the catalogue that publishes a copper peptide percentage, names three separate peptides, and states a fragrance-free formulation — three things a shopper can actually check before buying. At 30 mL for $21 it is the smallest serum Amplified Glow sells and the most expensive per millilitre. The full ingredient list is not published as text anywhere we could find, so anyone screening for a specific ingredient still cannot do so from the website alone.
Who it fits
Best fit for
- Shoppers who want a disclosed copper peptide percentage rather than an unquantified ingredient mention.
- People who prefer fragrance-free leave-on products.
- Anyone who wants more than one named peptide in a single serum.
- People trying a peptide serum for the first time who prefer a smaller, lower-cost bottle.
Consider another option if
- You want the lowest cost per millilitre — the 60 mL Copper Peptide Renewal Serum is roughly half the price for the same volume.
- You need to read a complete ingredient list before applying anything to your skin.
- You want a moisturizing step rather than a lightweight leave-on serum.
What this product is
The Amplified Glow™ GHK-Cu + SNAP-8 Peptide Renewal Serum is a 30 mL leave-on facial serum. Amplified Glow positions it as a daily product used after cleansing and before moisturizer, and states that the formula contains 0.15% GHK-Cu alongside SNAP-8 and Acetyl Hexapeptide-3.
Two details separate it from the rest of the skincare range. First, it is one of only three Amplified Glow skincare products that publish a copper peptide percentage at all, and the 0.15% figure is the highest disclosed anywhere in the skincare catalogue. Second, Amplified Glow explicitly describes it as fragrance free, which the brand does not say about most of its other creams and cleansers.
It sits alongside a second, larger copper-peptide serum in the same range. The relationship between the two is covered in our side-by-side comparison of the two Amplified Glow copper peptide serums.
Formula and ingredient context
Amplified Glow names three peptides on this product page. Only one of them carries a published concentration.
| Disclosed name | INCI name | Disclosed concentration | Evidence status |
|---|---|---|---|
| GHK-Cu | Copper Tripeptide-1 | 0.15% | Brand disclosed |
| SNAP-8 | Not verified | Not disclosed | Not verified |
| Acetyl Hexapeptide-3 | Not verified | Not disclosed | Not verified |
The GHK-Cu row is straightforward: Amplified Glow states the percentage, and its own FAQ equates GHK-Cu with Copper Tripeptide-1, the standard ingredient name. That 0.15% is the brand’s own figure — there’s no independent lab result published to check it against, which is normal for cosmetics.
The other two peptides need a little care. SNAP-8 is a supplier’s trade name, not the name that appears on an ingredient list. The two aren’t interchangeable, and Amplified Glow doesn’t publish the ingredient list for this serum, so there’s no way to confirm exactly what SNAP-8 corresponds to here. Our SNAP-8 page explains why that distinction is worth knowing.
The third peptide is listed as Acetyl Hexapeptide-3. The peptide usually sold under that description is more often written Acetyl Hexapeptide-8 — and Amplified Glow’s own older serum used the -8 spelling — so it’s worth treating the two as possibly the same ingredient under different names rather than assuming.
Beyond the peptides, Amplified Glow discloses sodium hyaluronate, betaine and trehalose as moisture-supporting ingredients, plus a botanical blend that includes cactus, oat bran, ophiopogon japonicus root, peony root, scutellaria baicalensis root and purslane extracts. What we cannot tell you is the order any of these appear in, or what else is present, because no text ingredient list is published.
Routine fit
Amplified Glow directs users to apply 2–3 drops to clean skin, massage into the face and neck until absorbed, and use morning and evening or as desired, following with moisturizer and sunscreen during the day. That places it in the standard serum slot: after cleansing, before the leave-on moisturizing step.
The brand pairs it with its own creams, and the directions on both the GHK-Cu + SNAP-8 Copper Peptide Cream and the Copper Peptide Renewal Cream describe applying cream after a serum has absorbed. If you are layering the two, our guide to layering a serum and moisturizer explains the ordering logic.
One routine question the brand does not address: whether to use this alongside the Brightening Vitamin C Serum, and in what order. Amplified Glow sells both and does not publish guidance on combining them. We have written what is and is not known about combining vitamin C and copper peptide products rather than invent an answer.
Price and value context
At the time of our last price check, the serum was listed at $21.00, reduced from a $25.00 regular price. That works out to $70.00 per 100 mL at the sale price, or $83.33 per 100 mL at the regular price.
Within the Amplified Glow range that is the highest price per millilitre of any facial serum. The Copper Peptide Renewal Serum is $30.00 for 60 mL, which is $50.00 per 100 mL — about 29% less per millilitre — though it discloses a lower 0.1% GHK-Cu concentration and a different peptide pairing. The Brightening Vitamin C Serum is also 60 mL, at $21.00, or $35.00 per 100 mL.
Price per millilitre is a fair comparison between products of the same format and a poor comparison across formats or across formulas with different disclosed actives. How to interpret price per ounce sets out when the calculation is informative and when it misleads.
Strengths and limitations
Strengths
- Publishes a copper peptide concentration — 0.15% GHK-Cu — which most of the Amplified Glow catalogue does not.
- Explicitly stated as fragrance free, which is useful if you avoid added fragrance.
- Names three separate peptides rather than one.
- Directions, frequency, routine position, warnings and patch-test guidance are all published.
- The lowest total outlay of the Amplified Glow facial serums, at $21.00.
Limitations
- The full ingredient list is not published as text on the product page.
- The highest price per millilitre of any Amplified Glow facial serum.
- Two of the three named peptides carry no INCI confirmation and no concentration.
- The packaging is not described, so you cannot tell whether it uses a dropper or a pump before ordering.
- No published guidance on combining it with the brand's own vitamin C serum.
What we could not establish
Amplified Glow does not publish these, and we have not confirmed them. We record them as open questions rather than guessing.
- The full ingredient list — Amplified Glow doesn’t publish it as text on the product page.
- The INCI name printed for SNAP-8 on this label.
- Concentrations of SNAP-8 and Acetyl Hexapeptide-3.
- Dispensing mechanism.
- Whether the botanical extracts are present at functional levels or as minor additions.
Safety and patch-test information
Amplified Glow publishes the following for this product: for external use only, avoid contact with eyes, discontinue use if irritation occurs, and a recommendation to patch test before first use.
That patch-test recommendation is worth following for any new leave-on product. How to patch test a new cosmetic product describes a practical method.

Be the first to review it →Frequently asked questions
How much GHK-Cu does this serum contain?
Amplified Glow states 0.15% GHK-Cu on the product page — the highest of any serum in its skincare range. That’s the brand’s own figure; cosmetics rarely come with an independent lab result to confirm it.
Is this serum fragrance free?
Amplified Glow states that it is. That is one of the few explicit fragrance statements in the catalogue — most other Amplified Glow skincare pages make no fragrance claim at all.
What is the difference between this and the Copper Peptide Renewal Serum?
This serum is 30 mL with 0.15% GHK-Cu plus SNAP-8 and Acetyl Hexapeptide-3. The Copper Peptide Renewal Serum is 60 mL with 0.1% GHK-Cu plus Palmitoyl Tripeptide-1. Both are fragrance free. The larger bottle costs less per millilitre. We compare every published attribute side by side on the comparison page linked below.
Can I see the full ingredient list before buying?
Not from the product page as text. Amplified Glow publishes hero ingredients in prose and shows the ingredient panel only in packaging photography. If you need to screen for a specific ingredient, contact the brand before ordering.
Has anyone at Amplified Glow Reviews tested this on skin?
No. This is a Formula & Specification Review — a close look at the product’s published details rather than a hands-on test. So it covers ingredients, size, price, and fit, but not how the serum feels or performs in use.
Evidence notes
Everything factual on this page came from the Amplified Glow product page and shop listing, checked on the date shown at the top of this page. Size, price, sale status, the 0.15% GHK-Cu figure, the fragrance-free statement, hero ingredients, directions and warnings all come from those two sources.
No laboratory testing, certificate of analysis, or hands-on trial informed this review. Where the brand does not publish something, this page says so rather than estimating.

GHK-Cu + SNAP-8 Peptide Renewal Serum vs Copper Peptide Renewal Serum
They differ on four published attributes: size (30 mL versus 60 mL), disclosed GHK-Cu concentration (0.15% versus 0.1%), the second named peptide (SNAP-8 and Acetyl Hexapeptide-3 versus Palmitoyl Tripeptide-1), and price per millilitre ($70.00 versus $50.00 per 100 mL). Both are fragrance free and neither publishes a full ingredient list. Choose the 30 mL serum if the higher disclosed concentration or the lower total price matters most; choose the 60 mL serum if cost per millilitre matters most.
Compare attributes →Product comparisonSerum vs Cream: Choosing a Format
If you already use a moisturizer you are happy with, buy the serum — it adds the peptide step without replacing anything. If you do not currently use a moisturizer, buy the cream, because a serum is not designed to be the last leave-on step. On price, the creams give more product per dollar in this range: the 50 mL GHK-Cu + SNAP-8 cream is $40.00 per 100 mL against $70.00 for the 30 mL serum.
Compare attributes →Product comparison30 mL vs 60 mL: Value and Usage Considerations
Only if you finish it. The 60 mL Copper Peptide Renewal Serum is $50.00 per 100 mL against $70.00 for the 30 mL GHK-Cu + SNAP-8 serum, but it costs $9.00 more up front and discloses a lower copper peptide concentration. If you have not used a copper peptide serum before, the smaller bottle caps what you spend to find out whether the format suits you — and an unfinished large bottle is worse value than a finished small one at any price per millilitre.

GHK-Cu
GHK-Cu is a small peptide complexed with copper. In cosmetics it appears under the INCI name Copper Tripeptide-1 and is used as a conditioning ingredient. It is the ingredient every Amplified Glow copper peptide product is built around, and the only one for which the brand publishes concentrations — between 0.1% and 0.15% depending on the product.
Read the ingredient page →Peptide (identity unconfirmed for the labels reviewed here)SNAP-8
SNAP-8 is a trade name suppliers use, not the standardised (INCI) name that appears on an ingredient list. Amplified Glow names it for three products but doesn’t publish the ingredient list, so the exact ingredient behind "SNAP-8" on these labels can’t be confirmed — and a trade name and an ingredient-list name aren’t interchangeable.
Read the ingredient page →Polysaccharide salt; humectantSodium hyaluronate
Sodium hyaluronate is the sodium salt of hyaluronic acid, used in cosmetics as a humectant — an ingredient that attracts and holds water. It is the most widely used ingredient in the Amplified Glow range, disclosed in eleven of the fifteen products.

How to compare peptide serums
Compare the attributes that are actually published and actually comparable: disclosed concentration, net contents, price per millilitre, fragrance status and whether a full ingredient list exists. Do not compare on peptide count, marketing language, or research about isolated ingredients — none of those distinguishes one finished product from another.

A Formula & Specification Review works from published information: ingredients, size, price, directions, warnings. A hands-on review works from documented use over a recorded period. The first can tell you what a product is; only the second can tell you what it is like to use. Every review on this site is currently a Formula & Specification Review, because no one here has documented testing of these products.
Read the guide →GuideHow to layer a serum and moisturizer
Serum first, moisturizer second. The reason is practical: the lighter, more water-based product goes on before the heavier one that helps hold it in place. Wait until the serum has absorbed — usually under a minute — rather than timing it precisely. Reversing the order is not harmful; it just makes the serum step less useful.
