Hyaluronic acid is having a moment in the skincare world. It seems like just about everyone is looking for the perfect hyaluronic acid serum to add to their routine. 

There are plenty of different hyaluronic acid serums available on the market, but today, we’re focusing on two in particular: the  Small Batch Serums Hyaluronic Pure Boost Serum  and  The Ordinary Hyaluronic Acid 2% + B5 Hydrating Serum.  These two formulas share quite a bit of similarities, but there are a few key areas where they differ. If you’re thinking of adding either to your routine, here’s a deep dive into how they compare, and how to choose the best option for your skin’s needs. 

The Ordinary vs. Small Batch Serums Hyaluronic Acid Serums

Purpose

The dermatologist tested and approved  Small Batch Serums Hyaluronic Pure Boost Serum  has a simple yet effective list of science-backed ingredients that promote hydrated skin and a youthful complexion. It helps the skin retain moisture so that it’s able to stay healthy and supple long-term. This gentle and lightweight formula immediately absorbs into the skin, and is suitable for all skin types. 

On the other hand,  The Ordinary Hyaluronic Acid 2% + B5 Hydrating Serum   similarly works to improve hydration levels at different layers of the skin. It helps soften and plump the skin for a younger-looking and hydrated complexion. It also has a lightweight formula, and is safe for all skin types (although those with acne-prone skin should use with caution – we’ll talk more about why below). 

Ingredient Breakdown

Both the Small Batch Serums and The Ordinary serums are powered by sodium hyaluronate, which is the salt form of hyaluronic acid. Compared to hyaluronic acid, sodium hyaluronate has a lower molecular weight. This means it is able to more effectively penetrate the skin, offering the best possible hydrating and plumping benefits. 

Additionally, both of these formulas feature propanediol. This ingredient works alongside the sodium hyaluronate, pulling moisture to the skin and preventing water loss.  

As far as ingredients go, this is where the similarities between the two formulas end. The Small Batch Serums product is simpler and cleaner compared to The Ordinary formula, and the only additional ingredients are water and two non-toxic preservatives to maintain the integrity of the formula.  

The Ordinary serum, on the other hand, also features panthenol and a sodium hyaluronate crosspolymer, which both work to hydrate different layers of the skin. Additionally, it contains glycerin (another humectant), as well as a range of different preservatives and texture enhancers. 

Another ingredient in The Ordinary formula worth noting is ahnfeltia concinna extract – also known as red marine algae extract. This ingredient is often used to improve the texture of skincare formulas, and also has antioxidant properties. For those prone to breakouts, however, this extract can cause issues, as it is a comedogenic ingredient – meaning it has a higher risk of clogging pores. 

How to Use Them

Since both The Ordinary and the Small Batch Serums products share the same star ingredients and serve similar purposes, they can be used in the same way. After cleansing, apply a few drops of your serum of choice to your face, neck, and chest, and then follow up with a moisturizer. Since they are gentle on the skin, these serums can be used both morning and night. 

Results

These serums both have effective formulas that can help boost the skin’s hydration while improving its ability to retain moisture. Reviewers agree that both formulas immediately promote a softer, comfortable, and more supple complexion, and do so without irritating the skin. These formulas also help minimize the appearance of fine lines for a youthful glow. 

Overview

Ultimately, these hyaluronic acid serums have a lot in common. They both target the same key concerns (dehydration and promoting a more youthful appearance), and have gentle, lightweight formulas that can be used on a daily basis. 

There are, however, two big differences between these two formulas. For those with acne-prone skin, The Ordinary serum may be a riskier choice, since it’s made with a comedogenic ingredient. The Small Batch Serums formula, on the other hand, has a super simple list of ingredients – and none of them are known to clog pores. 

Speaking of ingredients, the other key difference is that the Small Batch Serums formula is aligned with clean beauty standards, whereas The Ordinary formula is not. 

Here’s our final overview of how these formulas compare to each other.
