THE PRODUCT FILES / 01–04
A provider-guided cream and three retail serums, examined through their public labels and offers. CoreAge Rx holds the sponsored first position.
Checked September 25, 2026. No hands-on testing or clinical ranking. Commercial disclosure.
Provider-guided cream
The 2% description, monthly offer, consultation route, and missing formulation details behind Bounce Back.
Ask for the exact peptide identity, complete cream base, supply quantity, and final terms before interpreting the headline percentage.
Label-based serum review
Ingredient names, the current promotional offer and stock notice, and product-specific compatibility directions.
A detailed ingredient list is useful; it does not cancel the product’s compatibility directions or current stock limitation.
Label-based serum review
GHK-Cu versus GHK, the water-based formula, bottle-size choices, and the scope of manufacturer study summaries.
NIOD distinguishes 1% GHK-Cu from 1% GHK. The two figures do not add up to a 2% copper-peptide claim.
Label-based serum review
The 50 mL offer, moisturizing ingredients, undisclosed peptide amount, and study footnotes behind the plumping claims.
The formula includes several hydrating ingredients; a visible plumping effect cannot be assigned to copper peptides alone.
