Beyond a percentage
Brands use these terms to distinguish versions. No universal range perfectly describes every product’s behaviour. If concentration is stated, consult the manufacturer rather than importing an unrelated range.
Compare actual versions
Versions with one name may differ in formula and balance, not only strength. Test separately and observe development. More expensive or concentrated need not be your favourite.
Check cost and use
Compare equal volumes, usable bottle size and context. Perceived duration also depends on scent, application and environment. A label cannot guarantee a number of hours.
A practical example
Two bottles share a name but use different concentration labels. Record volume, price, impression and development for each. If you prefer the reportedly less concentrated version, no rule requires choosing the other.
Identify the gift version
For a familiar fragrance gift, photograph full name and version with the owner’s agreement. Compare the sold reference, not packaging colour. A similarly named version is not the same gift without verification.
| Criterion | Check | Do not assume |
|---|---|---|
| Label | Exact name and version | Universal concentration |
| Experience | Development and personal preference | Guaranteed number of hours |
| Price | Equal-volume price and useful size | More expensive is always better |
Your checklist
- Identify exact version
- Compare equal volumes
- Test development separately
Frequently asked questions
Does eau de parfum always last longer?
Not universally. Compare actual references in your context rather than the label alone.
Does price per ml measure quality?
No. It is only a volume-based financial comparison.
