Mechanism of Action
GHK-Cu (glycyl-L-histidyl-L-lysine copper) is found naturally in human blood, but its levels decline with age. The copper-peptide complex activates genes involved in the synthesis of collagen, elastin, and glycosaminoglycans. It also has antioxidant and anti-inflammatory effects and stimulates extracellular matrix remodeling.

Rejuvenescimento cutâneo e cicatrização
Tópico (creme/sérum)Aplicar em pele limpa, seguido de protetor solar
Estimula produção de colágeno e elastina. Estudos clínicos demonstraram redução de linhas finas em 8 semanas.
Queda capilar
Tópico (loção capilar) ou SubcutâneoAplicar no couro cabeludo
Aumenta folículos em fase anágena. Resultados comparáveis ao minoxidil 5% em estudos in vitro.
Benefits
Collagen stimulation
ProvenMultiple in vitro and clinical studies confirm increased production of type I and III collagen when applied topically.
View studyWrinkle and fine line reduction
Under researchSmall clinical studies demonstrated improved skin texture and wrinkle reduction after topical use of GHK-Cu creams.
Wound healing
Under researchEvidence of accelerated healing in animal studies and small clinical studies.
Risks and Side Effects

Low(Uncommon)May cause mild irritation on sensitive skin when used topically.
Internet vs. Science
What people say online compared to the actual scientific evidence.
Reverses aging
Partially trueWhat they claim
Promoted as a 'miraculous anti-aging' that reverses years of skin aging.
Actual evidence
Proven improvement in skin quality and collagen, but does not 'reverse' aging. Effects are modest and gradual. Topical use has more evidence than injectable.

PubMedFrequently Asked Questions
Does GHK-Cu work better topically or as an injection?
Most clinical studies used GHK-Cu in topical formulations (creams and serums). Topical application has more scientific evidence than injectable for skin effects.
