“—” means no specific record for that ingredient in that jurisdiction's lists — it is not an approval. Restricted ingredients are allowed within limits (concentration, product type, label warnings); a product listing one is not necessarily over the limit. How we check.

Ingredient list from Dear, Klairs official store, retrieved Oct 17, 2026. Formulas change — check the label on the package you buy.

Fragrance allergens (EU labelling)

None of the fragrance allergens the EU requires to be labelled appear in this ingredient list.

Source: EU Cosmetics Regulation Annex III as amended by Regulation (EU) 2023/1545 — the list grew from 26 to over 80 entries; it applies to new products from 31 July 2026 and to all products from 31 July 2028. Shown for information; it is not a sign that a product is unsafe.

Our note — heat, light & air

No ingredients on our heat/light/air list. Even so, cosmetics last longest closed, cool and out of direct sun.
