NEOVA Power Defense combines a branded copper-peptide complex with an antioxidant serum description. At its checked retail price, a reader may reasonably want more than the assurance that copper appears somewhere in the formula. The ingredient identity, study context and complete purchase record are the useful places to look.
This review is based on NEOVA’s official Power Defense page checked October 5, 2026. We examined the published product details and offer, without purchasing the serum, evaluating a batch or measuring a change in skin. Statements about intended results remain attributed to the manufacturer.
What trial design supports the particular Power Defense outcome being advertised?
What Copper Peptide Complex names
The Power Defense page identifies Bis (Tripeptide-1) Copper Acetate in its copper-peptide description. It also presents an antioxidant blend and a tetrapeptide in a lightweight gel-serum. That is a more specific record than the broad phrase copper peptide, but it still leaves the entire finished formula relevant.
The branded complex name does not disclose every concentration or prove a particular delivery result. A proprietary delivery statement should be read alongside the underlying ingredient declaration and any evidence provided for that delivery claim. A product’s trademark is an identifier, not an independent laboratory measurement.
The Minimalist record is a useful label comparison because it also names Bis (Tripeptide-1) Copper Acetate. The products’ other ingredients and marketing approaches differ. A shared INCI name does not erase those differences or establish equivalent finished-product performance.
Percentage improvements need a study design
NEOVA publishes improvement claims and links a clinical-study record from the product page. The numbers can look decisive when separated from the conditions that generated them. Before relying on a percentage, identify what was measured, who participated, how long the observation lasted and whether there was a control or comparison group.
A change from a study participant’s starting point is not automatically the difference a buyer would see versus an ordinary moisturizer. A participant-perception result is also different from an instrument measurement. We have not independently audited the full Power Defense study or replicated its results, and do not present those numbers as a guarantee.
Our evidence-reading guide keeps those distinctions visible. It is particularly useful for a product whose positioning emphasizes repair, environmental stress and skin resilience. The precise endpoint matters more than a broad impression that a product has been clinically proven in every respect.
The premium offer is still a retail bottle
The checked page listed $120 for 1 fl oz. That is a dated product-price observation, not a final delivered quote. A professional-stockist link or a direct retail purchase may involve different fulfillment and return arrangements, so retain the seller identity as well as the brand name.
Do not convert that price into a monthly treatment cost without a supported supply duration. We have not tested how much a pump dispenses or how long one bottle lasts for a particular routine. The cost article explains why a quantity and a calendar term cannot be exchanged by assumption.
For context, Remedy’s copper-peptide serum offers a different formulation and price record. That comparison can reveal differences in disclosed ingredients and purchase terms. It cannot establish that the more expensive product is more effective, or that the less expensive one is an equivalent substitute.
Separate antioxidant positioning from protection claims
The product description discusses environmental stress and antioxidants. Those claims should not be read as a sunscreen rating or as evidence that another protective routine step can be omitted. Our sunscreen note explains why peptide and sun-protection questions need separate records.
The full ingredient list is also important for someone considering the serum alongside existing products. FDA’s labeling overview provides general context for that list, while AAD’s product-testing guidance addresses introduction of an unfamiliar cosmetic. Neither establishes that this specific serum is suitable for every reader.
The most productive follow-up question is narrow: which part of the Power Defense evidence supports the exact outcome being discussed? Save that question with the product’s current ingredient declaration and selected offer. The workbench provides a way to compare those records without converting a trademark, study percentage or retail price into a clinical ranking.
