What is the Difference Between Serum and Moisturizer?

🆚 Go to Comparative Table 🆚

The main difference between serums and moisturizers lies in their texture, concentration of active ingredients, and function. Here are the key differences:

  1. Concentration: Serums have a higher concentration of active ingredients, such as antioxidants, vitamins, and peptides, due to their smaller molecular size. Moisturizers, on the other hand, have a lower concentration of active ingredients and are designed to hydrate and lock in moisture.
  2. Texture: Serums are lightweight and have a thin consistency, allowing them to be easily absorbed into the skin. Moisturizers are thicker and form a protective barrier on the skin's surface.
  3. Function: Serums are designed to penetrate deeply into the skin, delivering active ingredients to target specific skin concerns. Moisturizers work on the surface of the skin, creating a barrier to lock in moisture and prevent dehydration.

Both serums and moisturizers are essential components of a skincare routine, as they hydrate and nourish the skin in different ways. To use them effectively, apply serum after cleansing and toning but before moisturizing. This allows the active ingredients in the serum to penetrate the skin fully, while the moisturizer helps lock in the benefits and create a protective barrier.

    Penetration Penetrates the skin's surface up to 10 layers deep. Mainly affects the surface layer of the skin.
    Molecule Size Smaller molecules. Larger molecules.
    Ingredients Water-based, often contains ingredients like hyaluronic acid and Vitamin C. Contains emollients and may have UV protection.
    Purpose Repairs the skin at a cellular level, improves skin firmness, smoothness, and luminosity, and reduces fine lines and wrinkles. Locks in moisture and nutrients, sealing the skin and preventing moisture loss.
