In short, copper peptides are less about short-term smoothing and more about long-term skin quality and resilience
Despite this, transient increases in plasma glutathione and its metabolites may support antioxidant defenses, modulate immune responses, and influence cellular signaling pathways
Other health issues include anemia, cystic fibrosis, cancer, Alzheimers, Parkinsons, cataracts, glaucoma, aging, alcoholism, hepatitis, memory loss, AIDS, chronic fatigue syndrome, osteoarthritis, and infertility in men

Insider Tip: Its important to point out that, as explained by the FDA, There are no Federal standards or definitions that govern the use of the term hypoallergenic. The term means whatever a particular company wants it to mean.38 INNBEAUTY Project states that Elastic Skin has been third-party clinically tested to verify its hypoallergenic and noncomedogenic status, but the company doesnt clarify exactly which allergens the product is free of
This may be due to copper's ability to enhance the expression of metalloproteinases (MMPs).16 MMPs normally regulate the degradation of collagen, and a specific one, MMP-1, may be responsible for the initiation of collagen fragmentation.17 Supporting this, a 2024 study noted that elevated MMP-1 levels appear to contribute to aging skin and that higher MMP-1 levels in mice led to:18 The loss and fragmentation of dermal collagen fibrils Contracted fibroblast morphology Reduced collagen production Increased expression of pro-inflammatory mediators Additionally, a 2016 study found that GHK-Cu significantly increased gene expression of MMP-1 and MMP-2 at the lowest concentration, which the studys authors considered to be one of the reasons the peptide was able to increase collagen and elastin production.19 So, what this could ultimately mean is that using too much GHK-Cu (or other copper peptides) may in theory increase the skins MMP-1 concentration above the levels involved in healthy collagen production, taking it into the collagen fragmentation and breakdown territory seen in older skin with naturally higher MMP-1 levels
