Is Sodium Lactate The Same As Lactic Acid?

In the realm of skincare and health, the terms “sodium lactate” and “lactic acid” are often mentioned in the same breath, leading to a common misconception that they are interchangeable. However, while they are closely related, they serve different purposes and offer unique benefits. Let's delve into the distinctions and similarities between sodium lactate and lactic acid, shedding light on their individual roles in skincare and beyond.

Understanding the Basics

Before we explore their differences, it's crucial to understand what each compound is:

Lactic Acid: A naturally occurring alpha hydroxy acid (AHA) found in dairy products, fermented fruits, and vegetables. Which fruit contains lactic acid?Apples, bananas and pears are all examples.

List of specific applications: Lactic acid in skincare routine can significantly exfoliate the skin, helping to remove dead skin cells and promote a brighter, more even complexion.

Sodium Lactate: This is the sodium salt of lactic acid. It's produced by neutralizing lactic acid with sodium hydroxide. Sodium lactate for sale is a humectant, which means it helps to retain moisture, making it a popular ingredient in moisturizers and other hydrating skincare products.

The Key Differences

Functionality in Skincare:pH Levels and Skin Compatibility:Enhancing Other Skincare Ingredients:
The primary difference between the two lies in their functionality. Lactic acid is celebrated for its exfoliating abilities, helping to improve skin texture and reduce the appearance of fine lines. On the other hand, sodium lactate in skin care is a champion of hydration, drawing moisture into the skin and keeping it locked in.Lactic acid has a lower pH, which is what gives it its exfoliating properties. However, this also means it can potentially irritate sensitive skin if not used carefully. Sodium lactate, being a salt, has a higher pH and is generally gentler on the skin, making it suitable for a wider range of skin types, including those that are sensitive.Sodium lactate can also enhance the effectiveness of other skincare ingredients by improving the skin's barrier function and overall health. This is not a primary function of lactic acid, which focuses more on renewing the skin's surface.

Incorporating Them into Your Skincare Routine

For Exfoliation: If your goal is to gently exfoliate and renew your skin's surface, incorporating products containing lactic acid is your best bet. Start with a low concentration and use it 2-3 times a week to avoid over-exfoliation.

For Hydration: For those seeking deep hydration, especially in dryer climates or seasons, look for products that list sodium lactate as one of the top ingredients. It can be used daily, both in the morning and at night, to maintain optimal skin hydration.

The Synergy of Sodium Lactate and Lactic Acid

While they have their distinct benefits, using sodium lactate and lactic acid together in a skincare routine can create a well-rounded approach to skin health. By combining the exfoliating power of lactic acid with the hydrating effects of sodium lactate, you can achieve a balanced, radiant complexion. However, it's essential to listen to your skin and adjust usage based on its needs and reactions.


Sodium lactate and lactic acid, though stemming from the same source, serve different purposes in skincare. Understanding their unique properties allows you to make informed decisions about your skincare routine, ensuring that you're providing your skin with what it needs to thrive.
