Best Hydrating Serums for Radiant, Plump Skin

Hydrating Serums

A healthy, glowing complexion starts with hydration. Serums packed with humectants and skin-replenishing ingredients lock in moisture, leaving skin soft, smooth, and plump. The right formula helps maintain the skin barrier, reducing fine lines and dullness. Here are some of the best hydrating serums to revive dehydrated skin.

1. Hyaluronic Acid Powerhouses

Hyaluronic acid holds up to 1,000 times its weight in water, making it a top ingredient for deep hydration. Look for serums with multiple molecular weights of hyaluronic acid. This allows moisture to penetrate different layers of the skin.

  1. SkinCeuticals Hydrating B5 Gel – A blend of hyaluronic acid and vitamin B5 helps retain moisture while improving elasticity.
  2. Drunk Elephant B-Hydra Intensive Hydration Serum – A lightweight gel packed with pro-vitamin B5 and pineapple ceramides for long-lasting hydration.
  3. The Ordinary Hyaluronic Acid 2% + B5 – An affordable option with three molecular weights of hyaluronic acid for multi-depth hydration.

2. Glycerin-Infused Formulas

Glycerin attracts water from the air, helping to maintain hydration throughout the day. It also strengthens the skin barrier and enhances elasticity.

  1. CeraVe Hydrating Hyaluronic Acid Serum – A mix of glycerin, hyaluronic acid, and ceramides ensures hydration without clogging pores.
  2. Neutrogena Hydro Boost Hydrating Serum – Lightweight and fast-absorbing, this formula contains glycerin and hyaluronic acid to quench thirsty skin.
  3. La Roche-Posay Hyalu B5 Serum – A soothing, hydrating formula with glycerin, hyaluronic acid, and vitamin B5 to plump and revitalize.

3. Antioxidant-Boosted Hydration

Serums with antioxidants fight free radicals while delivering deep moisture. These formulas repair the skin barrier and prevent premature aging.

  1. Vichy Mineral 89 – A minimalist serum with hyaluronic acid and Vichy’s volcanic water for intense hydration and resilience.
  2. Glow Recipe Plum Plump Hyaluronic Serum – Infused with three types of plums, hyaluronic acid, and silk proteins to support skin elasticity.
  3. iS Clinical Hydra-Cool Serum – A cooling, soothing formula with hyaluronic acid, vitamin B5, and centella asiatica to calm and hydrate.

4. Barrier-Strengthening Serums

Healthy skin holds moisture better. Serums with ceramides, peptides, and niacinamide repair and protect the skin barrier, locking in hydration.

  1. Paula’s Choice Resist Omega+ Complex Serum – A nourishing mix of omega fatty acids, ceramides, and antioxidants for deep moisture.
  2. Dr. Jart+ Ceramidin Serum – A ceramide-rich formula that strengthens the skin’s natural defenses while keeping it soft and hydrated.
  3. First Aid Beauty Ultra Repair Hydrating Serum – A soothing serum with peptides and colloidal oatmeal to restore balance and moisture.

Choosing the Right Serum

The best hydrating serums (เซรั่มเพิ่มความชุ่มชื้น, which is the term in Thai) depend on skin type and needs. Oily skin benefits from lightweight, water-based formulas, while dry skin thrives on rich, emollient blends. Sensitive skin types should opt for fragrance-free, gentle serums with soothing ingredients like aloe, centella asiatica, or vitamin B5.

Consistency matters. Apply serum to damp skin, followed by a moisturizer to seal in hydration. Over time, well-hydrated skin appears more radiant, smooth, and youthful.
