Minéral 89 Hyaluronic Acid Booster

Eighty-nine percent Vichy volcanic water fortified with hyaluronic acid, in a bouncy gel that plumps skin before the rest of the routine. It does one thing — daily hydration with a strengthened barrier — and does it with a minimalist, fragrance-free formula. The green-capped bottle became shorthand for sensible skincare.
