Vichy Mineral 89 Booster Serum
A daily skin booster serum with pure hyaluronic acid and Vichy volcanic mineralizing water, formulated to plump, hydrate, and repair the skin barrier. Rated 4.8 out of 5 stars from 683+ reviews, and an Amazon’s Choice pick.
Vichy is a dermatologist-recommended French pharmacy brand, and Mineral 89 has become one of its breakout hits worldwide, with a 4.8-star average from 683 reviews and Amazon’s Choice status. It’s the kind of product that consistently shows up in “best hyaluronic acid serum” roundups, backed by genuine clinical formulation rather than just marketing buzzwords.
Why It Actually Works (Not Just Marketing)
The formula pairs pure hyaluronic acid with Vichy’s signature volcanic mineralizing water, sourced from the brand’s own thermal spa in France and rich in 15 minerals. This combination is designed to both hydrate skin and fortify its natural barrier, making skin more resilient to daily environmental stress. The lightweight, fragrance-free, oil-free gel texture absorbs quickly without any greasy residue, which is a big part of why it works well as a booster layered under moisturizer, rather than replacing one.
Good For / Watch Out For
Good for: nearly all skin types, including sensitive skin, since the formula is fragrance-free and oil-free. It’s a strong layering step for anyone wanting extra hydration without added weight. Watch out for: as a booster serum, it’s designed to be used under a moisturizer rather than alone, so very dry skin types will still need a proper cream on top for full hydration.
