- REDUCES FINE LINES: Minimizes the appearance of fine dry lines and wrinkles while promoting elasticity and skin smoothness.
- PRO-VITAMIN B5: Enhances the skin’s moisture retention and supports the formation of essential barrier components like ceramides.
- 5 TYPES OF HYALURONIC ACID: Delivers hydration to multiple layers of the skin, improving moisture retention and skin suppleness.
The Ordinary Hyaluronic Acid 2% + B5 is a standout serum. It combines hyaluronic acid with ceramides for deep hydration. This formula is designed to provide immediate, long-lasting moisture while making your skin look smoother and plumper. It also reduces fine lines, promoting a youthful appearance.
When compared to other options, The Ordinary excels in delivering quick hydration. Its ingredient list focuses on effective hydration components, making it a top choice for dehydrated skin. Other products, like the Good Molecules Hyaluronic Acid Serum, also hydrate well but may not match the potency found in this serum.
A limitation is that some users may find it slightly heavier than a lightweight serum. If you prefer a lighter texture, consider a different option. However, for effective hydration, The Ordinary remains a top pick.
Pros
- Contains 2% hyaluronic acid for deep hydration.
- Includes ceramides to support the skin barrier.
- Reduces appearance of fine lines and wrinkles.
Cons
- Can feel slightly heavy for some users.

The Ordinary Niacinamide 10% + Zinc 1% is designed for blemish-prone skin. This serum helps improve skin brightness and smoothness within a week. It contains niacinamide, which is known for its ability to reduce shine and support the skin barrier.
While it hydrates effectively, its focus on oil control may not make it the top choice for those solely seeking hydration. Compared to The Ordinary Hyaluronic Acid 2% + B5, this product targets different skin concerns. The hydrating formula is lighter but may not provide the same level of moisture.
An honest limitation is that users looking for intensive hydration may find this serum lacking. It’s great for balancing oil and improving texture, but not a primary option for deep hydration.

How to Choose Serums
Choose Based on Key Ingredients
Look for serums with hyaluronic acid, ceramides, or niacinamide. These ingredients help hydrate and strengthen your skin barrier. For maximum hydration, aim for a product with at least 2% hyaluronic acid.
Consider Your Skin Type
If you have oily skin, choose a lightweight serum that absorbs quickly. A richer formula may be better for dry or mature skin. Always test a small amount first to see how your skin reacts.
Look for Additional Benefits
Some serums also target specific concerns like fine lines or blemishes. For example, niacinamide helps brighten skin and reduce the appearance of pores. Consider what other issues you want to address.
Check the Texture
A lightweight, watery texture is ideal for layering under other products. If you want a serum to use alone, a thicker texture may be more suitable. Always check the consistency before buying.
Assess the Packaging
Serums in opaque bottles help protect the ingredients from light and air. Choose a serum that comes in a dropper bottle for easy application and to avoid contamination.

Frequently asked questions
What is the best hydrating serum for dehydrated skin?
The Ordinary Hyaluronic Acid 2% + B5 is the best hydrating serum for dehydrated skin. It combines hyaluronic acid with ceramides for effective moisture.
How do I know if my skin is dehydrated?
Signs of dehydrated skin include dryness, tightness, and a dull appearance. You may also notice fine lines and an uneven texture.
Can I use a hydrating serum every day?
Yes, you can use a hydrating serum daily. It’s best to apply it after cleansing and before moisturizing for optimal results.
What should I look for in a hydrating serum?
Look for key ingredients like hyaluronic acid, glycerin, or ceramides. These help attract and lock in moisture for better hydration.
Are hydrating serums suitable for all skin types?
Most hydrating serums are suitable for all skin types. However, choose a lightweight serum for oily skin and a richer one for dry skin.
What to look for
Key Ingredients
The most effective hydrating serums often contain hyaluronic acid, which can hold up to 1,000 times its weight in water. Ceramides help strengthen the skin barrier and lock in moisture. Look for concentrations of at least 2% hyaluronic acid for best results.
Application Frequency
For best results, apply your hydrating serum twice daily. Use it in the morning, followed by sunscreen, and in the evening after cleansing. Consistency is key to seeing significant improvements in hydration.
Texture Matters
The texture of a serum can impact its effectiveness. Lightweight, water-based serums are best for quick absorption, while thicker, oil-based serums may provide longer-lasting hydration. Choose based on your skin type and preference.
Packaging Considerations
The way a serum is packaged can affect its shelf life. Opt for serums in dark bottles to protect from light and those with pumps or droppers to minimize contamination. This preserves the product’s effectiveness.
Hydration vs. Moisture
Understanding the difference between hydration and moisture is important. Hydration refers to water content within the skin, while moisture locks that water in. Look for products that provide both for the best results.
