Stay Young | February 6, 2026 6:40 PM CST
What Is a Moisturizer?
A moisturizer is a skincare product which is a cosmetic, cream, gel, or lotion based product designed to hydrate, soften, and protect the skin by locking in moisture and strengthening the skin's natural barrier.
What is Face Serum?
A face serum is a lightweight, fast absorbing, and highly concentrated skincare liquid designed to deliver active ingredients (like Vitamin C or hyaluronic acid) directly into the skin.
7 Key Differences Between Face Serum and Moisturizer
1. TextureFace serums are lightweight and watery and can be absorbed quickly by the skin whereas moisturizers are thicker and creamier and sit on the skin for a longer period of time.
2. PurposeThe main purpose of serums are to treat specific skin conditions like acne, dark spots, wrinkles or dullness. Moisturizers are designed to hydrate and protect our skin barrier.
3. ConcentrationSerums usually contain high concentrations of active ingredients such as vitamin C, hyaluronic acid, niacinamide etc. Moisturizers contain less concentrations than serums and focus more on hydration.
4. AbsorptionSerums are absorbed deeper into the skin because of their small molecules. Moisturizers work on surface level and locks the moisture.
5. Skin Type SuitabilitySerums can be used for all types of skin depending on formula. Moisturizers can be used according to skin types i.e. gel based for oily skin and cream based for dry skin.
6. Order of UseWe should always apply serum before moisturizer because it helps in treating skin and moisturizer helps in sealing everything in.
7. Can You Skip One?
You can skip a serum if your skin has no major concerns, but skipping moisturizer is not recommended, as every skin type needs hydration.
Serums help treat skin problems, while moisturizers keep the skin hydrated and soft. Using both together keeps your skin healthy, smooth, and glowing.
