If your skin feels tight, dry, or constantly dehydrated no matter how much moisturizer you apply, the missing step is often a true hydration serum. COSRX The Hyaluronic Acid 3 Serum is a Korean skincare essential designed to deliver deep, multi-level moisture for a plumper, smoother, healthier-looking complexion.
This lightweight hydrating serum is powered by hyaluronic acid to help skin retain moisture, improve softness, and support a balanced glow without heaviness. It’s the perfect choice for anyone searching for a Korean hyaluronic acid serum for dry or dehydrated skin in the USA.
Deep hydration for dry and dehydrated skin
Dehydration can make skin look dull, feel rough, and emphasize fine texture. This serum helps replenish moisture quickly, leaving your skin feeling refreshed, comfortable, and more supple throughout the day.
It’s an ideal daily treatment for anyone dealing with seasonal dryness, indoor heating, or tightness after cleansing. For more hydration-focused skincare, explore our collection for dry and dehydrated skin.
A gentle serum for sensitive skin routines
Hydration is one of the safest and most effective ways to care for sensitive skin. COSRX The Hyaluronic Acid 3 Serum is designed to moisturize without irritation, making it a great option for easily reactive skin types.
If you want a calming, non-stripping routine, pair this serum with other essentials from our sensitive skin collection.
Supports a healthier-looking skin barrier
When the moisture barrier is compromised, skin can feel dry, uncomfortable, and prone to redness. This hyaluronic acid serum helps support barrier-friendly hydration, making it a key step in routines focused on long-term skin comfort.
Combine it with moisturizers and gentle skincare staples from our damaged skin barrier collection for a stronger, smoother-looking complexion.
Lightweight hydration even for acne-prone skin
Even oily or acne-prone skin needs proper hydration. When skin is dehydrated, it may feel unbalanced and overproduce oil. This serum delivers water-based moisture without clogging pores, making it suitable for routines supporting acne-prone skin.
The texture absorbs quickly and layers perfectly under sunscreen or makeup.
This serum pairs beautifully with products from our Korean toners, daily treatments in Korean serums, and hydrating essentials from Korean moisturizers.
If you want intense hydration in a lightweight, everyday formula, COSRX The Hyaluronic Acid 3 Serum is a must-have for smooth, plump, healthy-looking skin.
