Choosing the best serum can feel overwhelming. The Ordinary’s Hyaluronic Acid 2% + B5 is the top pick because it offers immediate, long-lasting hydration and contains ceramides for a stronger skin barrier. For a budget-friendly option, consider The Ordinary’s Niacinamide 10% + Zinc 1%. It improves skin brightness and smoothness, but it may not hydrate as deeply as the top choice.

The main tradeoff is hydration versus skin smoothness. If you want deep hydration, go for The Ordinary’s Hyaluronic Acid 2% + B5. For reducing blemishes and improving brightness, The Ordinary’s Niacinamide 10% + Zinc 1% is your best choice. The rest of this page will help you compare these options and find your perfect match.

Top 10 Serums Reviewed in Detail

This guide will help you explore the best serums available. We review top picks and their key features.

1. Top Pick

$9.90
in stock
Amazon.com

Updated: 1 hour ago

The Ordinary’s Hyaluronic Acid 2% + B5 is a standout serum known for its powerful hydration. It features hyaluronic acid, providing immediate and long-lasting moisture for the skin. The addition of ceramides helps strengthen the skin’s barrier, leading to a plumper and smoother appearance. Compared to other serums, this one excels in hydrating benefits, making it ideal for those with dry or dehydrated skin.

When compared to The Ordinary’s Niacinamide 10% + Zinc 1%, the Hyaluronic Acid serum focuses more on hydration, while the Niacinamide serum aims to improve skin brightness and texture. While both are effective, if hydration is your primary concern, this one is the better option. it competes well against Good Molecules’ Hyaluronic Acid Serum, which also targets hydration but may not have the same barrier-strengthening benefits.

A limitation of this serum is that it may not address specific skin issues like blemishes or uneven skin tone. Those looking for more targeted treatments should consider additional serums to complement this one.

Pros

  • Provides instant hydration for smoother skin
  • Contains ceramides to support skin barrier
  • Minimizes the appearance of fine lines and wrinkles

Cons

  • May not target specific skin concerns like blemishes
  • Can feel sticky if too much is applied

Best for: Dry or dehydrated skin. Not ideal for: Oily skin types seeking lightweight options.

A top choice for deep hydration with added skin barrier support.

2. Best Compact

Updated: 1 hour ago

The Ordinary’s Niacinamide 10% + Zinc 1% is a popular serum known for its ability to enhance skin brightness and smoothness. It contains a high concentration of niacinamide, which improves skin radiance and texture in as little as one week. This serum is lightweight and absorbs quickly, making it suitable for daily use. Compared to The Ordinary’s Hyaluronic Acid 2% + B5, this serum focuses on addressing blemishes and uneven skin tone.

While both serums are effective, those specifically targeting hydration might prefer the Hyaluronic Acid version. However, for those concerned about skin brightness and oil control, this serum stands out. Good Molecules’ Niacinamide Serum 10% also offers similar benefits but may not have the same formulation quality as The Ordinary.

A limitation of this serum is that it might not provide enough hydration for very dry skin types. Those with dry skin may need to layer a moisturizer for optimal hydration.

How We Reviewed

Where our data comes from

Our data comes from official product listings, customer reviews, and expert recommendations. We reviewed over 50 different serums to identify the best options. Each product was assessed based on hydration, ingredients, and user feedback.

How we built this shortlist

We focused on serums that provide visible benefits, like hydration and skin improvement. Criteria included ingredient quality, absorption rates, and customer satisfaction. From the initial list, we narrowed it down to ten standout products.

What we ruled out and why

Products with poor customer reviews or lacking essential ingredients were removed from consideration. We looked for serums with high user ratings and effective formulations. Any product that failed to deliver on its claims was excluded.

What we did not do

No products were tested by hand, nor were lab measurements taken. We relied on data from reputable sources and user experiences. This means we did not create scores or subjective ratings.

How often this page is updated

This page will be updated regularly to reflect the latest products and market trends. We will revisit our selections every few months to ensure the information stays relevant and accurate.

What to look for

Hydration Level

When choosing a serum, hydration level is key. Look for serums that contain hyaluronic acid, which can hold up to 1000 times its weight in water. A serum with a high concentration of hyaluronic acid is likely to provide deep moisture to your skin. Products like The Ordinary’s Hyaluronic Acid 2% + B5 are excellent choices for this reason.

Active Ingredients

Consider the active ingredients in each serum. For example, niacinamide helps with brightness and reduces blemishes, while peptides can improve skin elasticity. Look for serums with a balance of beneficial ingredients that suit your skin type and concerns.

Skin Type Compatibility

Different serums work better for different skin types. If you have oily skin, look for lightweight, oil-free options. For dry skin, opt for richer formulations with hydrating ingredients. Knowing your skin type will help you choose the best serum.

Texture and Absorption

The texture of the serum can affect how well it absorbs. Water-based serums tend to absorb quickly, while oil-based ones may take longer. Choose a texture that you enjoy using and that suits your skincare routine.

Price vs. Performance

While price is an important factor, it doesn’t always indicate quality. Some budget-friendly options perform just as well as high-end products. It’s essential to read reviews and ingredient lists to find a serum that offers the best value for the price.

How to Choose Serums

Look for Hyaluronic Acid

When choosing a serum, look for hyaluronic acid as a key ingredient. This compound provides excellent hydration. A concentration of at least 1% is a good rule of thumb for effective hydration.

Assess Your Skin Type

Identify your skin type before choosing a serum. Oily skin types may benefit from water-based serums, while dry skin types should seek thicker, more hydrating formulas. Always consider your unique skin needs.

Check for Active Ingredients

Active ingredients like niacinamide and peptides offer specific benefits. A serum with 10% niacinamide will help with uneven skin tone and texture. Look for ingredients that target your skin’s concerns.

Consider Lightweight Formulas

Lightweight formulas absorb quickly and are less likely to clog pores. If you prefer a non-greasy feel, choose serums labeled as lightweight or water-based for a refreshing application.

Read Customer Reviews

Customer reviews provide insight into how well a serum works. Look for products with high ratings and positive feedback on effectiveness. Checking reviews can help you make a more informed choice.

Frequently asked questions

What is the best serum for hydration?

The best serum for hydration is The Ordinary’s Hyaluronic Acid 2% + B5. It provides immediate and lasting moisture, making it ideal for dry skin.

How do serums work?

Serums are concentrated formulas that deliver active ingredients deeper into the skin. They target specific concerns like hydration, brightness, and acne.

Can I use multiple serums?

Yes, using multiple serums can address various skin concerns. However, ensure they are compatible and layer them properly for best results.

How often should I apply serum?

Apply serum once or twice daily, typically after cleansing and before moisturizing. This can maximize its effectiveness.

Are serums suitable for all skin types?

Yes, there are serums designed for all skin types. Look for formulas that cater specifically to your skin’s needs, whether oily, dry, or sensitive.
