Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.

Topically, glycerin does several things at once:

Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.

Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.

This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.

Just know very high concentrations (>40%) can feel tacky in low humidity.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

Phenoxyethanol is one of the most widely used preservatives in skincare (and for good reason!).

It has a large spectrum of antimicrobial activity and especially effective bacteria, yeast, and mold while only having a weak effect on your skin's natural microbiome.

On a cellular level, it disrupts the cell membranes of microbes by poking holes that make the cell leak. This shuts down the chemical reactions the microbe needs to make energy so it can no longer survive.

Another perk of this ingredient is that it stays functional across a wide pH range (3-10).

You'll often see it paired with boosters like Ethylhexylglycerin; one study showed that a 1:9 ratio of Ethylhexylglycerin to Phenoxyethanol damages bacterial membranes as effectively as doubling the Phenoxyethanol concentration on its own.

Typical use concentrations range from 0.3-1% depending on the formula, and this ingredient is capped at 1% int the EU.

Safety-wise, the fear mongering does not hold up to the evidence. The EU's Scientific Committee on Consumer Safety and FDA consider it safe as a preservative at up to 1%, including for children of all ages.

Adverse systemic effects only showed up in animal studies at exposures roughly 200x higher than what people get from cosmetics. And despite its very widespread use, this ingredient is a rare sensitizer and allergic reactions are uncommon.

Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.

You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!

GHK-Cu Copper Peptide: What the Research Actually Shows

GHK-Cu Copper Peptide: What the Research Actually Shows GHK-Cu is one of the most studied peptides in skin science, and also one of the most misunderstood. It shows up in serums, in research papers, and on supplier pages — often with claims that outrun the actual evidence. This is a plain-English overview of what GHK-Cu is, what the published research has looked at, and how to tell a quality preparation from a marketing label. This article is for educational and research reference only. It is not medical advice, and Element products are sold for laboratory and research use. What GHK-Cu actually is GHK is a short peptide — three amino acids: glycine, histidine, and lysine — that occurs naturally in human plasma. On its own it's written GHK; when it's bound to a copper ion, it becomes the copper complex GHK-Cu. The peptide was first identified in the 1970s in work on why young human plasma behaved differently from older plasma in tissue culture. GHK levels in the body decline with age, which is part of why it drew so much research interest as a signal associated with younger tissue. How it's thought to work Two mechanisms come up repeatedly in the literature: Copper delivery. Copper is a required cofactor for enzymes involved in building and remodeling the extracellular matrix — the scaffolding of collagen and elastin that gives skin its structure. GHK binds copper with high affinity and appears to act as a carrier, helping shuttle it where cells can use it. Gene signaling. More recent work, including gene-expression studies, has reported that GHK influences the activity of a broad set of genes — some tied to tissue repair, antioxidant response, and remodeling. This is the mechanism most often cited when GHK-Cu is described as "resetting" older cells toward a more active state, though that framing is a simplification of what the data show. Both mechanisms are still active areas of study. The honest summary is that GHK-Cu is biologically plausible and well-characterized in the lab, not that every marketing claim is settled science. What research has examined Most of the meaningful evidence sits in three areas: Skin and matrix remodeling. In-vitro and animal studies have looked at GHK-Cu's effect on collagen and glycosaminoglycan production and on markers of skin firmness. Small topical cosmetic studies have reported improvements in appearance metrics like fine lines and elasticity. Wound and tissue repair. A large share of the original research was in wound-healing models, where copper-peptide complexes were studied for their effect on repair signaling. Antioxidant and protective activity. Several papers report antioxidant behavior and protection against certain forms of cellular stress in model systems. The strongest, most replicated data is in the topical cosmetic context. Claims that reach beyond skin — systemic or therapeutic effects — rest on thinner, mostly preclinical evidence. Forms and formulation GHK-Cu is most familiar as a topical cosmetic ingredient, formulated into serums and creams at low concentrations, where its skin-remodeling research is most directly relevant. In a research setting it's typically supplied as a lyophilized (freeze-dried) powder to be reconstituted for lab work. A practical note on formulation: GHK-Cu carries a characteristic blue tint from the copper, and it doesn't play well with every ingredient — strong acids and certain antioxidants can destabilize the complex. That's a formulation constraint worth knowing if you're evaluating a finished product. Stability, storage, and handling For a research-grade lyophilized peptide, the standard handling principles apply: Store the sealed powder cold and away from light; freeze-dried peptide is far more stable than peptide in solution. Once reconstituted, keep it refrigerated and understand that stability is measured in weeks, not months. Avoid repeated freeze-thaw cycles, which degrade peptides. Copper complexes are light-sensitive — amber vials and minimal light exposure help. These are storage and stability considerations, not a use protocol. How to evaluate quality This is where most buyers get burned, and it's the part worth your attention: Third-party COA. A legitimate supplier provides a Certificate of Analysis from an independent lab, not just an in-house claim. Purity by HPLC. Look for stated purity (commonly ≥98%) verified by high-performance liquid chromatography. Identity confirmation by mass spectrometry, confirming the material is actually GHK-Cu and at the right molecular weight. Correct copper complexation. GHK and GHK-Cu are not the same material; the COA should reflect the copper complex. If a supplier can't produce a current, batch-specific COA, treat the purity claim as marketing. Frequently asked questions Is GHK-Cu the same as GHK? No. GHK is the bare tripeptide; GHK-Cu is GHK bound to a copper ion. Most skin research is on the copper complex. Why does it turn things blue? The blue color comes from the copper. It's normal and expected in a genuine GHK-Cu preparation. Is the skin research strong? The topical cosmetic and in-vitro skin data are the best-supported. Broader systemic claims are mostly preclinical and should be read with that in mind. What should I check before buying? A current, third-party COA showing HPLC purity and mass-spec identity for the specific batch. No COA, no confidence. Element supplies research-grade materials for laboratory use.
