Daily Hydrating Serum
What Is the Vichy Mineral 89?
The Vichy Mineral 89 is a lightweight, daily hydrating serum built around two active humectants — Hyaluronic Acid and Polyglutamic Acid — combined with Vichy's proprietary mineral-rich Volcanic Water sourced from Vichy, France. The formula contains only 11 ingredients and is free from fragrance, oil, parabens, silicones, and colorants. It is designed to be used as the first step in a skincare routine after cleansing — on damp skin — to immediately boost hydration, strengthen the moisture barrier, and improve how every product layered on top performs. It is clinically shown to improve skin hydration by 100%, and 93% of users in self-assessment felt instant hydration on first use.

In-Depth Review
TL;DR — Quick Verdict
The Vichy Mineral 89 is a genuinely effective, no-fuss hydration serum that works for almost every skin type. The minimalist formula, fast absorption, and dermatologist backing make it one of the most trustworthy entry-level serums available. It delivers exactly what it promises — better hydration, plumper skin, and a smoother base for everything you layer on top. At a low-to-medium price point with over 46,000 positive Amazon reviews behind it, this is one of the easiest recommendations on this site.
Results & What to Expect
The Vichy Mineral 89 delivers results quickly and they build over time.
On first use, skin feels instantly more hydrated and plump. The gel texture absorbs within seconds and the effect is immediately noticeable — skin looks refreshed and less dull. After one week, dry patches become less frequent and your moisturizer and SPF sit more smoothly on top.
After one month, skin texture visibly improves. Fine lines caused by dehydration soften, and several long-term Amazon reviewers mention that people started asking about their skincare routine around the 4-6 week mark.
What this serum does not do: it will not erase deep wrinkles, treat breakouts, or correct pigmentation. It is a hydration product. Used for that purpose, it consistently delivers.
Key Ingredients & How They Work
Hyaluronic Acid (Sodium Hyaluronate) — draws moisture from the environment and deeper skin layers to the surface, providing immediate visible plumping. Hyaluronic acid can hold up to 1,000 times its weight in water, making it one of the most effective hydrating ingredients in skincare.
Polyglutamic Acid — a newer ingredient that works alongside hyaluronic acid. While HA draws moisture in, polyglutamic acid forms a film over the skin to lock it there. The combination delivers both immediate hydration and longer-lasting retention — something most single-ingredient HA serums cannot claim.
Vichy Volcanic Water — the brand's proprietary ingredient, sourced from Vichy, France. This mineral-rich thermal water contains 15 minerals including calcium, magnesium, and potassium. It strengthens the skin barrier and protects against environmental aggressors, and it is what separates this serum from other HA products at a similar price.
The rest of the formula is intentionally minimal — no fragrance, no parabens, no silicones, no colorants.
How to Use It
Apply 2 drops to clean, slightly damp skin — morning and/or evening
Spread with outward movements from the centre of the face
Allow to absorb fully before applying moisturizer
In the morning, follow with SPF
Key tip: Apply to damp skin. Hyaluronic acid needs moisture to draw from — applying it to completely dry skin in a dry environment can pull moisture from deeper skin layers instead of the air, which can leave skin feeling more dehydrated over time.
What It Feels Like
The texture is a lightweight, water-based gel — almost like water with a slight slip. It spreads easily, absorbs within seconds, and leaves skin feeling smooth and slightly plumped with no heaviness or greasiness. Makeup and SPF sit on top without pilling. The only noticeable sensation is a very brief tackiness in the first 2-3 seconds after application — this disappears completely as it absorbs and is a non-issue in practice.
What Real Users Say
The most consistent feedback centres on three things: instant hydration, texture, and how well it works alongside other products. "It feels like my skin is getting a glass of water every morning and night," wrote one verified Amazon buyer in January 2026.
A 74-year-old reviewer who has used it for two years noted that people regularly ask how her skin looks so smooth — and credits consistent use of this serum. Another buyer described it as "the perfect first step in my skincare routine" that helps every other product apply more easily.
The most honest critical reviews question the value — some feel there is nothing uniquely transformative about it compared to cheaper HA serums. That is a fair point. Where Mineral 89 earns its edge is the Polyglutamic Acid pairing with HA, the 15-mineral Volcanic Water, and the clinical testing across 3,900 people — credentials that most drugstore serums at a similar price cannot claim.
Is it worth it?
Yes, and it is one of the easiest recommendations at this price range.
The Vichy Mineral 89 sits at a low-to-medium price point — accessible for a serum with this level of clinical backing. The formula is minimal, the results are consistent, and it works across every skin type including sensitive and eczema-prone skin. The bottle lasts approximately 2-3 months with twice-daily use, making the cost per use genuinely low.
If you are new to serums and want a reliable starting point, this is it. If you already use a more complex serum routine, this works as an excellent first layer underneath everything else.
Who It's Best For
Anyone starting a serum routine for the first time — easy, gentle, and effective
People with dry, dehydrated, or combination skin who want consistent daily hydration
Anyone with sensitive or eczema-prone skin looking for a clinically safe serum
People in their late 20s and older starting to address early fine lines from dehydration
Anyone who wants a high-performance first step that makes every other product work better
Not necessary if you are in your early 20s with naturally oily and well-hydrated skin — a lighter, cheaper HA serum would do the same job at a lower cost.
