Eye Serum
Eye Serum — a lightweight, fast-absorbing treatment for the eye area that delivers concentrated active ingredients in a fluid, often water-based texture. It typically layers under an eye cream or moisturizer and focuses on targeted concerns such as hydration, dark circles, or the look of fine lines and puffiness.
Key points
- Its thin, quick-absorbing texture makes it easy to layer before a richer eye cream or moisturizer.
- Serums usually carry higher concentrations of targeted actives than creams.
- Common ingredients include hyaluronic acid, caffeine, peptides, and niacinamide for hydration and a smoother, brighter appearance.
- It is applied gently around the orbital bone, avoiding direct contact with the eyes.
Frequently asked
What is the difference between an eye serum and an eye cream?
An eye serum is lighter and more concentrated in actives, while an eye cream is richer and more moisturizing; the two can be layered, serum first.
Do I need both an eye serum and an eye cream?
Not necessarily; using both can layer targeted actives with moisture, but many people find a single well-chosen product meets their needs.
