When it comes to hydration heroes, hyaluronic acid serums have earned their spot in every skin care routine. This powerful humectant is known for its exceptional water-binding capacity, making it one of the most effective ingredients for delivering deep, lasting moisture to the skin. But Vichy has taken its iconic Mineral 89 Daily Serum and made it even better, introducing a new powerhouse ingredient to the mix: Polyglutamic Acid.

Meet the new Vichy Mineral 89 Hydrating and Plumping Daily Booster Serum, now formulated with Hyaluronic Acid, Polyglutamic Acid and Vichy Volcanic Water for visibly plumper, more radiant skin.

Understanding hyaluronic acid, polyglutamic acid and your skin

Hyaluronic acid is a naturally occurring substance in the skin that helps maintain moisture and plumpness. As we age, our natural HA levels decline, leading to dryness, fine lines and loss of volume.

"Hyaluronic acid is one of the most valuable ingredients in skin care because it's suitable for virtually every skin type and concern," explains Dr. Joel Schlessinger, board-certified dermatologist and LovelySkin CEO. "It works by attracting and binding water molecules, which helps keep the skin hydrated, plump and smooth."

The new Mineral 89 Booster pairs this tried-and-true hydrator with polyglutamic acid, a next-generation ingredient that complements hyaluronic acid's moisture-drawing abilities. While hyaluronic acid pulls water into the skin, polyglutamic acid helps seal that moisture in, making the two ingredients a highly effective hydrating duo.

Topical hyaluronic acid serums work by drawing moisture from the environment into the skin's surface layers, creating an immediate plumping effect while supporting the skin's moisture barrier over time. Different molecular weights of hyaluronic acid penetrate to different depths in the skin. Low-molecular-weight hyaluronic acid can penetrate deeper layers, while high-molecular-weight hyaluronic acid works primarily on the surface to lock in moisture and create a smooth, hydrated appearance.

Why the new Vichy Mineral 89 Booster stands out

The updated Vichy Mineral 89 Hydrating and Plumping Daily Booster Serum is formulated with hyaluronic acid, polyglutamic acid and Vichy's signature volcanic water, a mineral-rich ingredient sourced from the French volcanoes. This unique water contains fifteen rare minerals that help fortify the skin's moisture barrier and protect against environmental stressors.

The formula's lightweight, non-sticky gel texture is fast absorbing to deliver instant hydration and radiance for visibly plumper skin. And because it's fragrance-free, it's safe for all skin types, including sensitive skin.

Clinical studies on the original Mineral 89 formula have shown that the serum can strengthen the skin's barrier function and improve resilience against external aggressors like pollution and stress. Users report immediate hydration, with skin feeling plumper and smoother after just one application.

How to incorporate Mineral 89 into your routine

For best results, apply Vichy Mineral 89 Hydrating and Plumping Daily Booster Serum to clean skin morning and evening. Dispense two or three drops onto your fingertips and gently press into your face and neck, avoiding the eye area. The serum absorbs quickly, creating the perfect base for your moisturizer and other treatment products.

Dr. Daniel Schlessinger, board-certified dermatologist, cosmetic surgeon and LovelySkin Medical Director, notes, "The key to maximizing hyaluronic acid's benefits is proper layering. Apply it to damp skin and follow with a moisturizer to seal in the hydration. This layering technique helps prevent transepidermal water loss and keeps skin hydrated throughout the day."

Mineral 89 layers beautifully with other serums and treatments. Apply it after cleansing but before heavier serums or treatments, allowing each layer to absorb before adding the next. Its lightweight texture won't interfere with makeup application, making it an ideal morning serum.

The science behind volcanic water

What makes Vichy volcanic water special? This thermal spring water has been filtered through layers of volcanic rock for thousands of years, emerging enriched with fifteen minerals including calcium, magnesium and silica. These minerals help support the skin's natural defense mechanisms and provide antioxidant protection.

"Mineral-rich thermal waters have long been valued in dermatology for their soothing and barrier-strengthening properties," says Dr. Joel Schlessinger. "When combined with proven hydrators like hyaluronic acid and polyglutamic acid, these mineral waters can enhance the overall effectiveness of the formulation."

Research has shown that Vichy volcanic water can help calm inflammation, support skin barrier function and improve the skin's ability to retain moisture. When combined with hyaluronic acid and polyglutamic acid, these minerals work synergistically to deliver both immediate and long-term hydration benefits.

Real results you can see and feel

Users consistently report visible improvements in skin texture and hydration within days of incorporating Mineral 89 into their routines. The immediate plumping effect helps minimize the appearance of fine lines, while continued use supports healthier, more resilient skin over time.

The serum's universal appeal lies in its science-backed simplicity. Whether you're dealing with dryness, dullness, sensitivity or early signs of aging, the new Mineral 89 Booster provides a foundation of hydration that allows your other skin care products to work more effectively.

Dr. Daniel Schlessinger adds, "Consistent use of hyaluronic acid serums can make a significant difference in skin health. The ingredient not only provides immediate hydration but also helps support the skin's natural moisture retention over time, leading to long-term improvements in texture and appearance."
