GHK-Cu has not been approved by the FDA for these uses.
The Science of GHK-Cu
Clinically studied and naturally occurring: GHK-Cu is a naturally occurring peptide that declines with age.1 It binds to skin cell receptors to enhance gene expression related to repair and renewal, reducing the activity of enzymes that degrade skin structural proteins with age, and helping restore the skin’s natural regeneration processes.3
Supports skin repair and resilience: GHK-Cu’s antioxidant activity may help protect against oxidative stress from UV and environmental exposure, preventing photodamage and discoloration.5 It may also support collagen and elastin production, improve firmness and texture, and reduce inflammation that drives chronic skin conditions over time.4

FAQs
What is GHK-Cu Cream?
GHK-Cu (Copper Tripeptide-1) is a naturally occurring peptide found in the body that supports skin repair and renewal processes, including collagen production and overall skin quality.4 Levels of GHK-Cu naturally decline with age.1 While GHK-Cu is not FDA-approved to treat medical conditions, it is commonly used in cosmetic dermatology for skin appearance and rejuvenation.2
How does GHK-Cu Cream work?
GHK-Cu Cream works locally within the skin layers (epidermis and dermis).1 Research suggests it may help support collagen and elastin production, promote tissue repair and remodeling, help regulate inflammatory signaling in the skin, support skin barrier integrity, and provide antioxidant activity within the skin.5 7 This treatment is intended for external skin use only.
What benefits can I expect from GHK-Cu Cream?
Individual results vary, and benefits are not guaranteed. With consistent use, some users may notice benefits such as improved skin firmness and elasticity, reduction in the appearance of fine lines, improved skin texture and tone, support for recovery from environmental stressors, and enhanced overall skin appearance.3
