A bunch of studies from 2012 "confirms the ability of copper peptides to improve aging skin conditions, which make them indispensable in anti-aging and protective cosmetic products." Several research theories suggest that "bioactive peptides hold great potential for cancer therapy and diagnostics." Thereby indicating that peptides are safe for topical use

This may include instances where: You need a stronger product to achieve your goals (e.g., deep hyperpigmentation, severe acne, etc.) You already use another product containing copper (this could be unsafe) An essential part of your skin care routine is a harsh active, vitamin C, strong exfoliant, or salicylic acid many of which are common ingredients in acne treatments and anti-aging products (copper peptides shouldnt be mixed with them) Using copper peptides may be unsafe (i.e., you have Wilsons disease, a peptide allergy, or active/suspected cancer) Youve tried a copper peptide product in the past and experienced an adverse reaction (e.g., copper uglies or troublesome side effects) If youd like some alternatives to copper peptides, we go over a few in the Alternatives to copper peptide serums section later in this guide
Proper dosage ensures safe and effective preparation
Gram-level dosing on himself is either brave or reckless depending on how it turned out So the dose is basically guesswork because the vial size became the default
The main mechanisms include stimulating the expression of follicle-related growth factors, dilating scalp blood vessels and improving microcirculation, boosting the differentiation and proliferation of hair follicle epithelial cells, and activating the Wnt/-Catenin signaling pathway and its key proteins (Scheme 2)
