Facial Serum vs. Facial Moisturizer - What's the Difference?

Serums and moisturizers help the skin in different ways. Sometimes a serum alone will be enough for what your skin needs, and other times you're going to find that you need both a serum and a moisturizer.В Serums are typically thinner and lighter than moisturizers, and have a wide variety of functions. Typically, serums have active ingredients in them that you want to penetrate deeply as possible into your skin.В For this reason, you should always apply a serum directly to your skin after cleansing or toning and before your moisturizer and sunscreen. They absorb quickly, and can be used both morning and night. They're not meant to replace your moisturizer, but can be used to boost its hydrating effects.

Serums are usedВ to address a variety of skincare issues. For example, there are anti-aging serums,В skin brightening serums, and acne prevention serums. Serums tend to be more expensive than other skin care products, but being that they're full of potent ingredients, a little goes a long way.

Moisturizers are thicker and creamier than serums. They're meant to hydrate the skin and prevent water loss. Some moisturizers have added anti-aging ingredients, so they do double duty for your skin. But in order to really address a difficult skin care problem, like sun damage, you'll want to combine your moisturizer with a quality serum.В

Moisturizers to Try

A moisturizer has larger molecules than a serum. This means that a moisturizer won't penetrate the skin as deeply, or as quickly, as a serum will. This is a double-edged sword: if you're looking for strong effects you should be relying on your serum, but if you're looking for continuous hydration, that's your moisturizer's job.

Bottom Line

If you have a problem with your skin that you'd like to improve, such as dark spots or early signs of skin aging, adding a serum to your daily skin care routine can help improve the appearance of your skin. And if your skin is super oily, a serum can give you enough hydration that you won't even need a moisturizer. However, for those suffering from dry skin, the right serum and moisturizer combo can make all the difference.
