Ingredients Explained

These ingredients are found in both products.

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

Copper Tripeptide-1 (GHK-Cu) is a skin repairing ingredient known for its ability to boost collagen, improve firmness, and support skin regeneration.

It is a complex made up of a naturally occurring peptide (glycine-histidine-lysine) and copper, an essential trace element.

While 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.

Some 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.

Anecdotal 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.

Unfortunately, there are limited human studies for this ingredient. While early results are promising, many studies are either small, in-vitro, or not rigorously controlled.

For example, there is a 1998 study that explored the effects of copper tripeptide, vitamin C, tretinoin, and melatonin on skin repair and collagen synthesis.

After 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.

While 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.

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. 03Hyaluronic 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.
  4. 04Topically, HA is a humectant that binds water and helps skin look more plump, smooth, and hydrated.
  5. 05The 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.
  6. 06Some clinical evidence links low molecular weight versions to improved wrinkle depth, elasticity, anti-inflammatory effects, and barrier repair.
  7. 07This is why the best HA serums blend the two sizes together so you get the best of both worlds.
  8. 08The 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%.
  9. 09A clinical study using a 0.2% low-molecular weight HA gel showed improvement in facial seborrheic dermatitis with excellent tolerance.

Copper Peptides: Molecular Characterization, Mechanistic Biology, and Emerging Research

by Dr. Usman | Jul 10, 2026 | Research GHK-Cu is the most extensively characterized member of this class. It is a tripeptide originally isolated from plasma albumin fractions and subsequently detected in saliva, urine, and wound fluid.[11][6] Research has attributed broad biological activity to GHK-Cu, encompassing extracellular matrix (ECM) remodelling, gene expression modulation, antioxidant pathway activation, wound repair facilitation, and neuromodulatory effects in preclinical models.[13] DAHK-Cu is a tetrapeptide corresponding to the N-terminal copper-binding domain of serum albumin, studied principally for its role in copper(II) transport, redox regulation, and neuroprotective signalling.[2] AHK-Cu (PubChem CID 168431292) is a tripeptide investigated for its capacity to stimulate dermal fibroblast activity, modulate growth factor expression, and influence follicular biology.[4][13] Contents: Copper Peptides Historical Development Copper Peptides Coordination Chemistry and Proposed Mechanisms of Action GHK-Cu and Extracellular Matrix Biology: Collagen Synthesis and Matrix Metalloproteinase Regulation GHK-Cu and Wound Repair: Comparative Preclinical Models GHK-Cu in Neuropathic Ulcer Models GHK-Cu and GHK-Cu-Loaded Biomaterial Dressings: Wound Healing Research GHK-Cu and Antioxidant and Anti-inflammatory Signalling in Pulmonary Models GHK-Cu and Neuromodulatory Biology: Anxiety, Aggression, and Pain GHK-Cu and Cognitive Resilience in Aged Animal Models AHK-Cu: Dermal Fibroblast Activation, Collagen Synthesis, and Hair Follicle Biology References Featured Product
