Does expensive mean better?

Price and quality are related in cosmetics, but weakly, and not in the direction most people assume.

The materials in a bottle are usually a modest fraction of what you pay. The rest covers packaging, filling, testing, warehousing, distribution, retail margin, marketing, and company overhead. A more expensive product is not automatically buying you a better formula; it may be buying heavier glass.

Some genuine differences never appear on a label: stability programmes, preservative efficacy testing, supplier qualification, retained samples, and the documentation behind each batch. These add real cost and real assurance, and they are easy to skip quietly.

Complex formats, difficult ingredients, small production runs, and thorough quality programmes all cost more to do properly. The question is whether a company can explain where the money goes in specific terms. If the explanation is only atmosphere, the price is atmosphere.
