Hyaluronic acid has become one of the most recognizable ingredients in modern skincare. You’ll find it in serums, moisturizers and other hydrating products — but what does hyaluronic acid actually do for your skin?
Despite the word “acid” in its name, hyaluronic acid isn’t primarily used to exfoliate the skin. It is a humectant, which means it can attract and hold onto water.
That makes it a popular ingredient in skincare routines focused on hydration.
What Is Hyaluronic Acid?
Hyaluronic acid is a substance that occurs naturally in the human body, including in the skin.
In skincare products, it is commonly used because of its ability to bind water. This can help the skin feel hydrated, smoother and more comfortable.
Unlike exfoliating acids such as glycolic or salicylic acid, hyaluronic acid is mainly associated with hydration rather than exfoliation.
What Are the Benefits of Hyaluronic Acid?
The main reason people add a hyaluronic acid serum to their skincare routine is hydration.
A hyaluronic acid product can help:
- Support skin hydration
- Help the skin feel softer and smoother
- Reduce the feeling of dryness or tightness
- Add a lightweight hydrating step to a skincare routine
Results can vary depending on the formulation, your skin and the other products in your routine.
Who Can Use Hyaluronic Acid?
Hyaluronic acid can be found in products designed for many different skin types.
If you have dry skin, it can add another layer of hydration to your routine.
If you have oily or combination skin, a lightweight hyaluronic acid serum may provide hydration without the feel of a heavier cream.
People with sensitive skin may also encounter hyaluronic acid in gentle formulas, although the complete ingredient list of a product still matters.
How Do You Use Hyaluronic Acid Serum?
Hyaluronic acid serum is generally used after cleansing and before moisturizer.
A simple routine could look like this:
Morning:
Cleanser → Hyaluronic Acid Serum → Moisturizer → Sunscreen
Evening:
Cleanser → Hyaluronic Acid Serum → Moisturizer
Always follow the directions provided with the specific product you are using.
Should You Apply Hyaluronic Acid to Damp Skin?
You’ll often see people applying a hydrating serum while their skin is slightly damp.
Because hyaluronic acid attracts water, applying it as part of a hydrating routine and following it with a moisturizer can work well for many people.
However, there isn't one application method that is perfect for everyone. Follow the instructions for your product and pay attention to how your skin responds.
Hyaluronic Acid vs. Moisturizer: Do You Need Both?
A hyaluronic acid serum and moisturizer don't necessarily serve exactly the same purpose.
A serum can provide a lightweight hydrating step, while a moisturizer can help support hydration and reduce moisture loss.
That means you don't necessarily need to choose between them.
For a simple routine, you can apply your hyaluronic acid serum first and follow with moisturizer.
Can You Use Hyaluronic Acid Every Day?
Many skincare products containing hyaluronic acid are designed for regular use.
How often you should use a particular serum depends on its complete formulation and the directions provided with the product.
If you're introducing a new product into your routine, starting gradually can also make it easier to see how your skin responds.
