Hypoallergenic cosmetics: what the claim can establish

A claim that cannot remove every reaction risk
Hypoallergenic does not mean that sensitisation is impossible. European cosmetic-claims guidance calls for substantiation without promising a complete absence of risk. In the United States, the FDA explains that the term has no standardised federal definition; those settings should not be confused when reading product information intended for different markets.
Prefer useful detail to an accumulation of labels
If you know an allergen to avoid, its name and the product’s ingredients provide more precise information than reassuring wording. Sensitive-skin ranges may offer starting points, while repeated reactions deserve appropriate investigation. Keep the packaging and reference so the exact product involved can be described clearly to the professional assessing the concern.
