What to look at

1. Keep a photo of the old label if you want a comparison.
2. Match the new market, variant and shade.
3. Compare exact names and record unresolved differences.

A little practice

Read this label.

Old list has fragrance; new package uses a different list

Illustrative excerpt · not a real product

Why this reading matters

Cosmetic ingredients are generally ordered by predominance, with exceptions for ingredients at one percent or less and color additives. The list is not a table of ingredient concentrations. US Food and Drug Administration.

Fragrance mixtures can be declared collectively. Unscented products may still use masking fragrance, so lack of a noticeable smell does not establish a fragrance-free formula. US Food and Drug Administration.

What the label cannot settle

A changed list does not by itself prove that the product caused or will prevent a reaction.

Put the check to work

Compare the exact words and amounts on your package with the example. If a panel is missing, a photo is unreadable or the manufacturer has not disclosed a detail, keep that detail as unknown. A different flavor, shade or formulation needs its own check.
