ghk-cu peptide topical use for Anti-Aging & Collagen Support - Copper Peptides Serum for Face QUBIT GHK-Cu Copper Peptide Face

A Nature Scientific Reports 2016 study showed GHK-Cu had no cytotoxicity to human keratinocytes at concentrations up to 5,800 M over 72 hours and did NOT induce inflammatory biomarkers (IL-1, IL-8, HSPA1A, FOSL1) unlike other copper compounds, concluding GHK-Cu has a low potential of inducing skin irritation

This can happen if you take long baths or showers or regularly swim in public pools

Avoid use with direct acids, retinoids, and strong antioxidants

Retinol accelerates cell turnover and has some collagen-stimulating effects, but it can cause irritation, dryness, and photosensitivity making it less ideal for patients with sensitive skin or those in sun-intensive environments like Ponte Vedra Beach

Apply the serum to clean skin, then follow with a gentle, non-acidic moisturizer
