Every comparison table on this site has cells that do not contain a value. Those cells are doing work, and this page explains what each one means.
The evidence states we use
- Verified
- Read directly from a source we can cite, and cross-checked against at least one other place the same fact appears.
- Brand disclosed
- Amplified Glow states it. We are reporting that accurately as a brand statement. We have not independently confirmed it, and for most formulation figures we have no way to.
- Packaging verified
- Read from a legible photograph of the physical product or its ingredient panel.
- Editorially inferred
- Calculated by us from verified inputs — price per millilitre is the usual case. The inputs are cited; the output is arithmetic.
- Not disclosed
- The brand does not publish this at the source we checked. The information may exist internally; it is not public.
- Not verified
- A value may exist and we have not confirmed it to our standard. Treated as unknown.
- Needs update
- Previously verified, now older than our freshness threshold for that field.
What none of them means
Not disclosed does not mean zero. A product with no published fragrance statement is not thereby fragrance free. A cream with no published peptide percentage is not thereby peptide-free — GHK-Cu is in the name.
Not disclosed does not mean the brand is hiding something. Most cosmetic brands do not publish concentrations, and there are ordinary commercial reasons for that. It is a gap in what you can check, not an accusation.
Brand disclosed does not mean verified. When we record 0.15% GHK-Cu, we are recording that Amplified Glow says so. We have not seen a certificate of analysis, and we do not present the figure as one.
Why we do not estimate
We could fill most blank cells with something reasonable. A peptide cream with no published percentage probably sits in the same range as its siblings. A serum bottle is probably a dropper.
We do not, for one reason: an estimate in a table looks exactly like a fact. Once written in a cell alongside verified values, a plausible guess is indistinguishable from a checked one, and the reader has no way to tell them apart. A blank labelled "not disclosed" cannot mislead anyone.
Claim wording is part of this too
The same care applies to how claims are worded. The Amplified Glow berry haircare line claims "Sulfate Free". The lavender line claims "Sulfate-Free Surfactants".
Those are not the same statement — one is about the whole formula, the other about one ingredient class within it. We record each exactly as published rather than normalising both to "sulfate free", because the difference is the information.
What we do with the gaps
Every unknown is listed plainly in the review, so you can see exactly what’s missing before you decide. When Amplified Glow publishes the detail, we add it and update the last-checked date on the page.
