Key ingredients

Copper Tripeptide-1Disclosed at 0.25% and provides the formula's central GHK-Cu signaling rationale for firmness, texture, and visible recovery.
SqualaneAdds lightweight emollience and helps reduce the dry, tight feel that can undermine nighttime treatment tolerability.
NiacinamideAdds barrier, skin-conditioning, and tone-support context within the moisturizer base.
GlycerinProvides core humectant support and helps maintain overnight hydration.
PanthenolAdds humectant and comfort support to the concentrated peptide treatment.

Price tier

$$$ Premium

Value check

At the Premium tier, you pay for disclosed copper-peptide content and a supportive night cream, while basic overnight hydration is available for less.

Bottom line

If you want a rich night cream with GHK-Cu, this formula pairs a substantial moisturizing base with a disclosed copper-peptide concentration. The Premium value depends on your interest in an emerging peptide approach, not proven facial lifting or wrinkle reversal.

What is Shopper Fit?

Shopper Fit shows who The Beauty Briefing finds the product is reasonably suited for after reviewing the complete formula or product design, product format, expected performance, directions, tolerability, usability, and available evidence.

Depending on the product category, Shopper Fit may reflect factors such as skin type, hair or scalp characteristics, product needs, routine compatibility, sensitivity, experience level, or practical use considerations.

Shopper Fit is BB's editorial product-fit assessment, not a copy of the brand's marketing. It is not a diagnosis, a guarantee of results or tolerance, or a claim that the product is suitable for everyone.

What are Shopper Preferences?

Shopper Preferences are product attributes The Beauty Briefing has enough evidence to treat as established for the exact product. A brand statement, badge, or retailer claim alone is not enough.

Vegan
BB found sufficient documentation to verify the vegan claim within the documented product scope.
Cruelty-Free
BB found sufficient documentation to verify the cruelty-free claim within the scope of the evidence reviewed.
Non-Comedogenic
BB found sufficient product-specific evidence or documentation to support the non-comedogenic claim. A brand claim by itself does not qualify.
Dermatologist-Tested
BB verified documentation showing the exact product was tested with dermatologist involvement. This does not mean dermatologist-recommended.
Ophthalmologist-Tested
BB verified documentation showing the exact product was tested with ophthalmologist involvement.
Hypoallergenic
BB found sufficient product-specific evidence or documentation to support the hypoallergenic claim. It does not guarantee that no shopper will react.
None Found
BB did not find sufficient evidence to verify any of the controlled Shopper Preferences for the exact product.

Brand marketing tells BB what to investigate. BeautyBrief tells the shopper what BB has established.

What are Formula Flags?

Formula Flags identify characteristics of a product's formula that materially affect shopper fit, tolerability, routine compatibility, or use. A flag does not mean an ingredient is bad or that the product is unsafe. It highlights something worth knowing before you buy.

Fragrance
Added fragrance or parfum that materially affects shopper fit or tolerability.
Essential oils
Essential oils that are relevant to fragrance exposure, sensitivity, or use.
Drying alcohols
Volatile alcohols at a level that materially affects feel, dryness, or tolerability.
Retinoids
Retinoid actives that affect routine compatibility, tolerability, or use.
Exfoliating acids
Exfoliating acids such as AHAs, BHAs, or PHAs at a functionally relevant level.
Comedogenic concerns
Formula characteristics that warrant additional consideration for breakout-prone shoppers.
Sulfates
Sulfate cleansing agents that materially affect cleansing strength, skin or hair feel, or shopper fit.
Silicones
Silicones that materially affect texture, finish, or shopper fit.
Added color
Added colorants that materially affect the finished formula or shopper use.
Other
Another formula characteristic materially affects shopper fit or use.
None identified
No defined Formula Flags materially affect shopper fit or use.

Formula Flags are informational. They are not a list of ingredients everyone should avoid.

If you want a richer nighttime moisturizer with a disclosed copper peptide, Alchemy 21/12 GHK Night Cream combines 0.25% Copper Tripeptide-1 with squalane, glycerin, niacinamide and panthenol. The formula provides a credible basis for overnight moisturizing comfort, but you should not confuse GHK-Cu ingredient research with results from this exact cream.[1]

The brand recommends introducing the treatment gradually on one or two nights per week, especially if you are starting its CORRECTV serum as well. It is a peptide-focused product rather than a necessary upgrade to a conventional moisturizer.

What it claims

Alchemy 21/12 positions GHK Night Cream as a retinoid-free overnight treatment for visible firmness, smoother texture, resilience, recovery, and age-related change. The brand describes 0.25% GHK-Cu as the central signaling ingredient and pairs it with niacinamide, ectoin, panthenol, betaine, squalane, and emollients to support comfort and moisture retention.[1]

Claims vs. formula

The hydration and comfort case is straightforward. Squalane, caprylic/capric triglyceride, dicaprylyl carbonate, cetearyl alcohol, glycerin, niacinamide, betaine, panthenol, and ectoin create a well-rounded moisturizing system that should improve softness, cushion, and overnight comfort.

The copper-peptide rationale is biologically plausible. Reviews of GHK-Cu describe effects on fibroblasts, collagen and glycosaminoglycan synthesis, matrix remodeling, antioxidant activity, and wound-repair signaling across laboratory, animal, ex vivo, and cosmetic research.[2] Those findings explain why the ingredient is interesting, but they do not establish the magnitude of visible anti-aging benefit from this finished cream.

The directly verifiable controlled human evidence is more restrained. In a randomized split-face study of 13 patients using copper tripeptide products after CO2 laser resurfacing, objective assessment found no statistically significant advantage for wrinkles or overall skin quality, although participants reported better overall skin-quality improvement on the GHK-Cu-treated side.[3] The study also involved post-procedure skin rather than ordinary nightly cosmetic use, so it cannot be transferred directly to this product.

Alchemy 21/12 explicitly distinguishes ingredient research from finished-product testing on its current page, which is appropriate. The brand also states that refrigeration is required to help protect peptide integrity and formula longevity.[1]

No controlled BB Formula Flag is identified. The formula is fragrance-free and does not contain retinoids, essential oils, drying alcohols, silicones, added color, or treatment-level exfoliating acids that require a flag.

Ingredients that matter

Squalane, caprylic/capric triglyceride and dicaprylyl carbonate soften your skin, while glycerin, betaine and panthenol support surface hydration. Niacinamide and ectoin add additional conditioning support in a fragrance-free cream base.

Copper Tripeptide-1 is listed as the GHK-Cu component, with the brand disclosing 0.25%. That provides an ingredient-level rationale for visible firmness and skin-support claims; it does not show that this particular product remodels dermal collagen or reverses biological aging.

Copper Tripeptide-1

Copper Tripeptide-1 is a copper-binding peptide used mainly for fine lines and firmness. Its biology is plausible, but ordinary topical anti-aging evidence remains indirect and highly dependent on the finished…

Squalane

If your skin feels dry or rough, squalane can make it feel softer and smoother. You don't need a separate oil when your moisturizer already keeps your skin comfortable.

Glycerin

If your skin feels dry or tight, glycerin helps your skin hold moisture. You don't need a high percentage or a separate serum when your moisturizer already works well.

What to expect in the short term

Expect the most immediate benefit to be moisturization: a richer, more cushioned feel and smoother-looking surface from the humectant and emollient base. The blue or light-purple hue comes from the copper-peptide complex and should disappear as the cream is spread into a thin layer.[1]

Alchemy 21/12 recommends applying the cream at night as the final step after cleansing, toner, and serums, starting conservatively at one to two nights per week and increasing as the skin becomes comfortable with it. The brand also recommends separating it from strongly acidic L-ascorbic acid and low-pH exfoliating treatments.[1]

What to expect over time

Consistent use should continue to support hydration, softness, and a more resilient-looking surface. GHK-Cu provides a plausible pathway for improvements in firmness and texture, but the amount of visible change from this exact finished cream remains unproven.

The brand advises giving the formula roughly 8 to 12 weeks for visible change, while also acknowledging that the supporting human research evaluated other GHK-containing creams rather than this finished product.[1] BB therefore treats firmness and wrinkle improvement as plausible long-term outcomes rather than clinically established results for GHK Night Cream itself.

Who it fits

If your skin is dry, normal or combination and you want a more cushiony nighttime product with an experimental peptide component, this may suit your routine. If you mainly want daily barrier comfort, a simpler moisturizer may be easier to justify.

Alchemy 21/12 identifies its GHK cream as vegan and states that the full product range is cruelty-free. These are brand declarations rather than evidence of copper-peptide efficacy.[1]

Compare before you buy

Alchemy 21/12 Recover-Me Barrier Cream is the more practical in-brand choice when the main goal is daily hydration, barrier support, and comfort rather than copper-peptide signaling. It is also a 50 mL moisturizer, uses ceramide NP, squalane, panthenol, beta-glucan, and Palmitoyl Tripeptide-8, and does not require refrigeration.[5]

GHK Night Cream makes more sense for shoppers who specifically want the disclosed 0.25% GHK-Cu treatment and are comfortable with cold storage, gradual introduction, and a higher-cost corrective step. Recover-Me Barrier Cream is the simpler choice when barrier support and moisturization are the primary need.

Final Assessment

Alchemy 21/12 GHK Night Cream is a well-constructed refrigerated night cream with a genuinely differentiated 0.25% Copper Tripeptide-1 concentration and a strong moisturizer base. The copper-peptide science is biologically interesting, but the finished-product clinical evidence does not match the strength of the mechanistic story. At the Premium tier, the value case is strongest for shoppers specifically committed to a retinoid-free copper-peptide approach and willing to accept the added refrigeration and evidence tradeoff.
