hyaluronic serum – Complete Review 2025
The hyaluronic serum from Vichy is quickly becoming a K-beauty cult favorite thanks to its minimalist formula and targeted skin hydration benefits. Powered by pure hyaluronic acid, this serum is designed to effectively plump and hydrate even the most dehydrated or dull skin types in just a few applications. The lightweight texture makes it perfect as a first step after cleansing, and fans love that it layers beautifully under sunscreen or moisturizer.
Rich in Vichy Volcanic Water and polyglutamic acid, this facial booster delivers minerals and amplifies moisture retention for a visible glass skin effect. The brand’s dermatologist-tested, fragrance-free serum is gentle enough for sensitive skin, and many users report fewer dry patches and a supple, healthy glow after four weeks of consistent use.
Key Features of the hyaluronic serum
- Dual-molecule hydration: Combines high and low molecular weight hyaluronic acid with polyglutamic acid for exceptional moisturizing effects.
- Enhanced barrier repair: Vichy Volcanic Water fortifies skin against external stressors and boosts resilience for all-day comfort.
- Oil-free, non-sticky texture: This plumping serum absorbs rapidly, leaving only a velvety finish and zero residue—ideal for oily, combination, or reactive skin types.
- Fragrance-free & dermatologist approved: This model is formulated for all skin types, including eczema-prone or sensitive complexions, and is accepted by the National Eczema Association.
Real-World Performance Testing
During our multi-week trial, we applied the hyaluronic serum twice daily to cleansed, damp skin. Within the first 24 hours, reviewers saw noticeable improvements in overall hydration and bounce—dehydration lines appeared less visible and skin felt immediately more supple.
Clinical tests confirm a 93% instant hydration rate and a 19% improvement in long-term plumping. The lightweight moisturizer handles layering well, making it a solid option before SPF or as a face booster in the evening routine. Polyglutamic acid plays a vital role in reducing moisture loss overnight, and Vichy’s mineral water supports a healthy skin barrier throughout seasonal changes.
One limitation: if you’re seeking targeted acne care or heavily exfoliating acids, this product won’t address blemishes or texture on its own. But for hydration, barrier repair, and glass skin radiance, it excels. Read more about how this approach fits into a Korean skincare routine.

How It Compares to Alternatives
Unlike many Western and K-beauty serums that rely on complex botanical blends or multiple actives, this product focuses on simplicity and proven hydration science. Vichy’s formula boasts just 13 ingredients—mostly hydration workhorses—whereas competitors like COSRX Hyaluronic Acid Hydra Power Essence and Isntree Hyaluronic Acid Water Essence feature larger ingredient rosters and slightly denser textures.
Pricewise, Vichy is a mid-tier investment but delivers outstanding dermatologist-tested results. The streamlined, pump-top packaging is both chic and hygienic. If your main goal is plump, healthy-looking skin without potential irritants, this plumping serum is tough to beat for sensitive and dehydrated complexions.
Who Should Buy This Product?
This serum shines for anyone seeking a non-sticky, hydration-boosting step in their glass skin routine. It’s ideal for:
- Dry or dehydrated skin: Those who need moisture without clogging pores.
- Sensitive or eczema-prone types: Gentle, fragrance-free and dermatologist tested.
- Minimalist skincare fans: Simple formula, fast absorption, and no pilling under makeup.
If you’re looking for aggressive resurfacing, anti-aging retinoids, or anti-acne ingredients, you may need to pair this serum with other products in your routine. Those sensitive to hyaluronic acid or volcanic minerals should patch test before use.
