GHK, Glycyl-L-Histidyl-L-Lysine
A synthetic tripeptide that binds copper to promote collagen synthesis, wound healing, and anti-aging effects in skin and tissues.

A facial serum with a manganese tripeptide applied twice a day for up to 12 weeks helped reduce visible sun damage and dark spots on the skin, moving the overall damage rating from moderate to mild, and it caused no irritation.

Scientists improved the skin‑friendly peptide GHK by attaching two tiny “address tags” – one that sticks to cell‑surface integrins (RGD) and another that binds chondroitin sulfate (sOtx2). These new versions, especially the RGD‑GHK combo, showed stronger antioxidant, anti‑aging and wound‑healing effects in lab tests and stayed longer in the skin when applied.

The study tested two new hair‑growth mixes (QR 678 and QR 678 Neo) that contain growth factors and copper‑tri‑peptide‑1. In lab dishes they didn’t hurt skin cells, and when injected under the skin of mice they grew new hair around the injection spot. The results are promising but have only been shown in mice, not people.

In a rat model of infant brain injury that causes epileptic spasms, the researchers found that a lack of IGF‑1 inside certain brain cells (interneurons) makes the spasms happen. Giving the animals a tiny piece of the IGF‑1 protein called (1‑3)IGF‑1 (a tripeptide) stopped the spasms, repaired the connections between those brain cells, and brought IGF‑1 levels back up. Similar cell changes were seen in tissue from human babies with the same disorder, suggesting the findings might translate to people.

A 12‑week study found that an eye cream containing a mix of ingredients—including the peptide palmitoyl‑tripeptide‑1—significantly improved skin hydration, elasticity, and collagen levels around the eyes, with no safety concerns reported.

A skin cream called Restorative Skin Complex (RSC) that contains the peptides Tripeptide‑1 and TriHex™ was tested and found to boost anti‑aging genes like Klotho and FOXO3, slow down telomere shortening in skin cells, and improve collagen and elastin structure in skin biopsies. The study was small, but the results suggest the product may help keep skin biologically younger.

In a lab study, tiny amounts of copper tripeptide and the skin drug tretinoin were added to human skin cells grown without serum. Copper tripeptide lowered the scar‑related signal (TGF‑beta1) in both normal and scar‑forming cells, while tretinoin boosted a growth factor (bFGF) linked to skin tightening in normal cells and raised TGF‑beta1 in scar‑forming cells after a longer exposure.

Researchers made several new versions of a tiny three‑amino‑acid peptide that was previously shown to boost blood‑vessel growth. In lab tests, three of the new peptides (called 5‑7) helped human endothelial cells multiply, move, and invade more than the original peptide, and one of them even repaired damaged vessels in zebrafish at very low concentrations.

Scientists found that a tiny piece of the IGF‑1 protein (called (1‑3)IGF‑1) can stop seizure‑like spasms in baby mice by re‑activating the IGF‑1 pathway in the brain. The study shows that loss of IGF‑1 in neurons is linked to these spasms, and giving the tripeptide restores normal signaling and eliminates the abnormal brain activity.

A small open‑label study tested a gel that contains copper tripeptide‑1 (along with other ingredients) on women with acne scars. Over 45 days the gel noticeably reduced scar visibility and improved skin smoothness and texture, with no reported side effects.

Researchers mixed a copper‑based tripeptide (CuTP1) with tiny silver particles and found that the combo helped skin cells close a wound in a lab test much faster than the peptide or silver alone. This suggests the mixture could be a more powerful ingredient for wound‑care products.

Scientists created a slightly altered version of the immune‑activating peptide fMLP and found that the change forces the molecule into a folded shape. This new shape makes the peptide lose its ability to attract white‑blood cells, but it still strongly triggers one type of immune response (superoxide production) and behaves like the original for another (lysozyme release).

Scientists discovered that a tiny three‑letter tag (SKM) at the end of a protein called human soluble epoxide hydrolase (hsEH) can send the protein into peroxisomes, but only under certain conditions. The tag alone isn’t enough – the protein needs to be made in large amounts or be shaped so the tag is exposed. This explains why hsEH is found both inside peroxisomes and in the cell’s fluid.

The study looked at how linking the side chains of tiny three‑amino‑acid peptides (tripeptides) changes the ways their backbone can bend. By forming rings through disulfide bonds, thioethers, or amides, the peptides become much less flexible, and the exact type and position of the ring determines how restricted they are.

The study shows a lab recipe for making a specially labeled three‑amino‑acid peptide that scientists use as a reference when they run solid‑state NMR scans. It’s a technical method for producing a research tool, not a health‑related supplement or therapy.

Scientists created a new, simple chemical reaction that sticks bright fluorescent tags onto tiny protein pieces (peptides) without needing harsh chemicals or catalysts. They showed it works quickly at body‑like temperature and used it to label a peptide called apelin‑13, which then lights up cells that have the apelin receptor.

Scientists studied a tiny three‑amino‑acid molecule (called CDPI3) that sticks into the narrow groove of DNA. When they attached it to the end of a short DNA strand, the pair of strands stuck together much more tightly, raising the temperature needed to melt them by about 30 °C. The overall shape of the DNA stayed normal, and the CDPI3 fit snugly in the groove.

Scientists attached a tiny molecule called CDPI3 to very short DNA pieces used in PCR tests. This makes the short pieces stick to DNA more tightly, letting them work as primers even when they’re only 8‑10 bases long. The trick could help amplify tricky viral genes, but it’s a lab technique, not a health supplement or therapy.

The study looked at how a worm parasite (Ascaris suum) grows from one larval stage to the next in a lab dish, testing different culture media, including one that added a tiny protein fragment (a tripeptide). The tripeptide didn’t make a big difference for the worm’s growth compared to normal serum, and the work is purely about parasite biology, not human health.

A novel tripeptide, 1, was isolated from the extracellular extract of a Pseudomonas-Alteromonas bacterium that was associated with the Black Sea sponge Dysidea fragilis. Compound 1 contains the novel beta-aminopimelic acid described for the first time from a natural product. The structure of 1 is suggested on the basis of the analysis of spectroscopic data and chemical degradation.
