The words “hydrating” and “moisturizing” are often used interchangeably, but in fact they have a few key differences, which can become important when picking products for your skin type. Read on to learn more about the difference between hydrating and moisturizing your skin.
01 What Is the Difference Between Hydrating and Moisturizing?
Ingredients that are moisturizing typically include lipids that help form a lubrication barrier on skin to trap moisture so it doesn’t escape. Moisturizing ingredients for the skin tend to have high water-binding capacities so that they can hold onto water molecules to provide a water source for skin. For your skin to achieve maximum hydration, you may consider using a product that provides both benefits or multiple products to hydrate and moisturize skin. And always remember skin hydration is an inside job! You must be sure to stay hydrated from the inside-out by drinking plenty of fluids and maintaining a diet full of foods that help your skin such as healthy proteins, fats, and antioxidants.
Distinguishing a hydrator from a moisturizer can be difficult, as some products achieve both functions, while others achieve only one.1 The best way to tell whether a skin care product is moisturizing or hydrating is by looking at its ingredients. Different ingredients deliver hydration versus moisture, and some provide both, including emollients and humectants.

Why Is It Important to Keep Your Skin Hydrated?

- Darker under eyes
- Sunken eyes
- “Shadows” around the eyes and nose

How to Hydrate Skin
In a 12-week clinical study, our peptide moisturizer, OS-01 FACE, improved skin hydration and skin barrier by an average of +15%. Additionally, cleansing skin with our gel cleanser, PREP, before applying OS-01 FACE was shown to enhance the hydration effects of OS-01 FACE, as shown by analyzing a key marker associated with hydration, AQP3, in lab studies on human skin samples.
03 Skin Moisture
Why Is It Important to Keep Your Skin Moisturized?
Signs Your Skin Is Dry
- Tight feeling skin
- Feels and looks rough
- Reddish or grayish skin
- Moisturizing aims to fortify skin’s lipid barrier to help lock in moisture
- Hydrating aims to attract and hold onto water molecules, creating a hydration source for skin
- Keeping skin both hydrated and moisturized is key to ensuring your skin cells have access to enough water to function properly
- If you have dry skin, consider using a moisturizer
- If you have dehydrated skin, consider using a hydrator
- Some products can be moisturizers and hydrators, depending on their ingredients
