LA MER
Ultra Booster Premium Mask Effect
€63.19
From the Cuxhaven marine house, not Estee Lauder's similarly named cream. The hook is North Sea silt in tenth place and five separate hyaluronic acid forms spread down the list - hydrolysed, acetylated, the plain sodium salt, a crosspolymer and hydrolysed sodium hyaluronate - which is more about molecular-weight marketing than five different jobs. Nine declared fragrance allergens is a lot for a leave-on.
What stands out in the list
Worked out from the ingredients, not the packaging claims.
Contains fragrance
Listed as Parfum/Fragrance, which can stand for dozens of undisclosed aroma chemicals. Fragrance is one of the most common causes of cosmetic contact allergy.
7 declared fragrance allergens
EU law requires these to be named on the pack: Hexyl Cinnamal, Linalool, Benzyl Salicylate, Limonene, Citronellol, Eugenol, Benzyl Benzoate.
2 concentration-capped ingredients
EU law sets a maximum for C15-19 Alkane. Products on sale in the EU must comply. It also sets one for Benzyl Salicylate, which products must comply with from 1 January 2027.
No drying alcohol
No ethanol, alcohol denat. or isopropyl alcohol in the list. Fatty alcohols such as cetearyl alcohol are not drying and do not count.
Nothing flagged for pregnancy
No ingredient on this list is one our encyclopaedia marks as avoided or used with caution in pregnancy. That is not the same as a clearance, so check with your midwife or doctor.
