Ingredients Explained

These ingredients are found in both products.

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

1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse.

It is a:

Humectant, drawing moisture into the skin

Emollient, helping to soften skin

Solvent, dispersing and stabilizing formulas

Preservative booster, enhancing the antimicrobial activity of other preservatives

Arginine is a semi-essential amino acid. This just means our bodies can product a bit on its own, but sometimes needs a little boost from food sources.

It is a part of your skin's natural moisturizing factor (NMF), or the water-loving molecules in your outermost layer of skin (stratum corneum) that keeps everything hydrated and happy.

Here's an interesting thing about Arginine: your skin converts it into urea through the Krebs-Henseleit urea cycle. Urea is one of the most effective humectants your skin naturally produces.

A clinical study showed applying 2.5% arginine hydrochloride to atopic dermatitis skin showed significant urea levels in the stratum corneum and improved moisture in just four weeks.

Arginine is also a precursor to nitric oxide; nitric oxide improves microcirculation and supports wound healing and collagen synthesis.

One study found that an amino acid complex containing Arginine reduced skin irritation, improved hydration, and accelerated skin repair in clinical / in-vivo studies.

Arginine itself is an amino acid and not a fatty acid, oil, or ester. On its own, it's not a direct food source for Malassezia, or the yeast that causes fungal acne.

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.

Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.

Hyaluronic acid (HA) is a glycosaminoglycan (basically a long sugar chain) that your skin already makes on its own. In your skin, HA lives in the extracellular matrix and acts as the body's moisture reservoir.

Topically, HA is a humectant that binds water and helps skin look more plump, smooth, and hydrated.

The only catch is that HA isn't a single thing; it actually comes in a wide range of molecular weights (~50 - 2,000+ kDA) and size matters.

Some clinical evidence links low molecular weight versions to improved wrinkle depth, elasticity, anti-inflammatory effects, and barrier repair.

This is why the best HA serums blend the two sizes together so you get the best of both worlds.

The majority of cosmetic HA is produced by bacterial fermentation, typically using Streptococcus or Bacillus strains. Typical use levels in skincare sit around 0.1-2%.

A clinical study using a 0.2% low-molecular weight HA gel showed improvement in facial seborrheic dermatitis with excellent tolerance.

These are some other common types of Hyaluronic Acid:

We don't have a description for Hydrolyzed Hibiscus Esculentus Extract yet.

This ingredient is created by putting sodium hyaluronate through hydrolysis.

You might know this as 'mini' or 'ultra low-molecular weight' hyaluronic acid. The small molecule size means it is able to travel deeper in the skin.

According to studies, low molecular-weight hyaluronic acid can:

One study from 2011 found ultra-low weight HA to show pro-inflammatory properties. Another study from 2022 found it to downregulate UV-B induced inflammation.

Hydrolysis is a process of changing a molecule using water or enzymes.

This ingredient is water-soluble.

Pentylene Glycol (1,2-pentanediol) is a multitasking little diol with three main roles in a formula:

Research on alkanediols (the family pentylene glycol belongs to) show they work by disrupting microbial cell membranes. This disruption helps the primary preservative system in a product work more effectively at lower doses.

On the safety side, the Cosmetic Ingredient Review Expert Panel has concluded this ingredient to be safe as used in current cosmetic practices + concentrations.

Typical use levels in a formula run about 1-5%.

Sodium Hyaluronate is the salt form of hyaluronic acid. It is a long sugar chain that is naturally found in your skin, joints, and connective tissue that maintains hydration and elasticity.

In skincare, it works as a humectant. It pulls water from the environment and deeper layers of skin and binds it to the surface.

Interestingly, the size of the molecule affects its behavior:

Many serums use a blend of both weights so you can get surface hydration plus longer-lasting and deeper effects.

You'll typically see concentrations between 0.1-2% for this ingredient.

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!

Ingredients Explained

  1. 01These ingredients are found in both products.
  2. 02Ingredients higher up in an ingredient list are typically present in a larger amount.
  3. 03Copper Tripeptide-1 (GHK-Cu) is a skin repairing ingredient known for its ability to boost collagen, improve firmness, and support skin regeneration.
  4. 04It is a complex made up of a naturally occurring peptide (glycine-histidine-lysine) and copper, an essential trace element.
  5. 05While studying wound healing, researchers noticed GHK-Cu stimulated hair follicle enlargement and growth by keeping hair in its active growth phase longer. This has made it a promising ingredient for hair regrowth treatments.
  6. 06Some people have reported increased facial hair. While GHK-Cu can make your hair follicles bigger, it usually doesn’t turn soft, barely-visible facial hairs into thick, dark ones.
  7. 07Anecdotal reports suggest that overusing copper peptides might lead to premature aging due to excess free copper or enzyme imbalances. This claim isn’t backed by large-scale studies.
  8. 08Unfortunately, there are limited human studies for this ingredient. While early results are promising, many studies are either small, in-vitro, or not rigorously controlled.
  9. 09For example, there is a 1998 study that explored the effects of copper tripeptide, vitamin C, tretinoin, and melatonin on skin repair and collagen synthesis.
  10. 10After one month, increased procollagen production was seen in 7 out of 10 participants using copper tripeptide (more than those using vitamin C, melatonin, or tretinoin.
  11. 11While the study was exploratory, it offers early evidence that copper tripeptide may support collagen production. Larger, well-designed trials are still needed to confirm its potential and understand individual responses.

Research note

Evidence Tiers: Sorting Strong From Suggestive

Because the claims about GHK-Cu and copper-dependent enzymes span everything from rigorous biochemistry to marketing copy, it helps to array the evidence by tier and by which of the three claims it supports. GHK binds Cu(II) in a stable, exchangeable complex Biophysical / spectroscopic1 Prerequisite for A Strong — well established GHK-Cu stimulates fibroblast collagen synthesis at nM levels In vitro3 Consistent with A/B Strong for the endpoint; indirect for LOX GHK-Cu increases collagen & matrix in rat wounds In vivo (animal)4 Strong for the endpoint; indirect for the enzyme GHK-Cu modulates MMP/TIMP balance in wounds In vivo (animal)8 Adjacent (matrix turnover) Moderate — concerns proteases, not cuproenzymes GHK shifts ~4,000 genes incl. antioxidant/ECM pathways Gene expression (cell lines)7 B (transcriptional) Suggestive — mRNA, not enzyme activity GHK-Cu upregulates antioxidant enzyme expression / cuts ROS In vitro6 B, weak A Suggestive — direct SOD copper-loading unproven Topical GHK-Cu improves wrinkle/elasticity parameters Small human topical studies13 Downstream of A/B Weak-moderate — small, industry-linked Direct measurement of GHK-Cu raising LOX/SOD catalytic activity in skin — Would prove A/C Largely absent The pattern in the table is the whole argument in miniature. The strongest, most reproducible data concern outcomes — collagen, matrix, wound closure, and gene-expression signatures. The specific step the title asks about — direct modulation of a named copper-dependent enzyme’s activity in skin — sits in the bottom row, where the evidence is thinnest. That is not a reason to dismiss the hypothesis; the outcome data make it plausible that cuproenzymes are involved. It is a reason to state the conclusion carefully.

Research note

Research in Copper Peptides

Copper proteins and naturally occurring peptides aim to assemble the building blocks necessary for a structurally sound and functional extracellular matrix in the skin, making copper peptides a potentially large focus in dermatological research. Small copper peptides have indeed been studied for their potential to induce tissue repair and remodeling, with research hypotheses suggesting downstream impacts spanning anti-inflammatory, and anti-antioxidant, and DNA repair potential. These copper peptides have attracted scientific notice for their purported potential to adjust gene expression. GHK-Cu is one such copper peptide and its mechanism of action has been widely speculated, as elucidated below.
