Creams vs. Serums: What’s the Difference?

Over here on eraclea’s skin care blog, we talk all the time about the importance of a daily skin care routine. But with so many products on the market, it’s hard to know which products are essential and which products may (or may not) be necessary for your unique skin. One of the most common questions we encounter when it comes to skin care:

What’s the difference between a facial cream and a serum?

They’re similar, but not the same. While everyone should use a facial cream on a daily basis for basic skin hydration and protection, serum is a more specialized lotion that delivers super-hydrating ingredients to the skin. Here’s an overview of each:

Facial cream

Facial creams hydrate and protect your skin. Different creams hydrate your skin to different extents. For example, eraclea creams use HylaFusion® to intensely hydrate the skin as well as deliver biologically active molecules, such as vitamin C, to the skin. They also create a protective barrier between your skin and the toxins in the outside world.

Some creams, like our Restorative Hydrating Night Cream, are thick and designed to firm, repair and restore the skin while you sleep. Others, like our Intensive Hydrating Day Cream, are lighter, and thereby designed to be worn throughout the day to hydrate your skin, protect it from dirt and pollution, and reduce the appearance of fine lines and wrinkles. And still other creams are more specialized, like our Eye Surround Cream, which is especially light to treat the delicate area around the eyes.

No matter your skin, everyone should use both a day cream and a night cream on a daily basis. This is an essential component of a good skin care routine.


Serums are super light, fast-absorbing ointments that typically do not contain oil. They are used to effectively deliver active ingredients like antioxidants, vitamins, and basic anti-aging elements. For example, our Pure Hydration Serum/Zinc treats irritated skin by drawing on the antibacterial and anti-inflammatory properties of zinc to promote healing while reducing redness.

Serums tend to be very powerful — a little bit goes a long way! While they aren’t necessary to a basic skin care routine, they can help reduce the signs of aging and eliminate irritation. Applying a small amount of serum before using face cream can help your skin maintain its healthy glow throughout the day — and over the years.
