Le Labo Rose 31 Eau de Parfum
At a glance
Summary
Le Labo Rose 31 Eau de Parfum scores 15/100 — the lowest of the Le Labo line, level with the very best mainstream designer scores. The rose-and-woods scent carries the heaviest allergen load in the entire luxury tier: ELEVEN declared EU sensitizers, including cinnamal and isoeugenol — two of the most potent contact allergens IFRA regulates (isoeugenol is capped at 0.02% in leave-on products precisely because of its patch-test record) — plus alpha-isomethyl ionone and santalol from the EU's expanded 2023 disclosure list, and unrectified-grade bergamot (phototoxicity risk). The undisclosed 'Parfum' core with no exclusion pledges does the rest. What keeps it AT the designer ceiling rather than below it: no synthetic dyes, no UV filters, no BHT, and disclosed rose, cedarwood and vanillin naturals — restraint that designer formulas with equal allergen counts (YSL Y at 15 adds three coal-tar dyes and avobenzone) do not show.
Key ingredients 27
Parfum (Fragrance)Very Bad
Trade-secret blanket term concealing the bulk of the formula. Le Labo (Estée Lauder-owned) publishes no exclusion pledge for polycyclic musks (Galaxolide, Tonalide) or phthalate carriers and carries no clean-beauty certification, so the blend cannot be independently verified — unlike certified brands whose pledges are vetted.
