Body serums are the most underused step in a dry skin routine. Lighter than a cream but more targeted than a lotion, they deliver concentrated active ingredients — hyaluronic acid, niacinamide, peptides — directly into the skin before you seal everything in with a heavier moisturizer. Think of them as treatment, not hydration.

For dry skin, look for serums built around humectants that draw moisture into the skin rather than just sitting on top. Hyaluronic acid and glycerin are the workhorses here. Niacinamide adds barrier-repair benefits and is well tolerated by most skin types, including sensitive skin.

Layering order matters. Apply your body serum to clean, slightly damp skin before your oil or cream — never after. A sealed barrier won’t let actives through. Give it 60 seconds to absorb before the next step.
