What is the difference between a serum and a moisturizer?

Serums and moisturizers are both skincare products, but they serve different purposes and have different formulations:

1. Serum:

   • Purpose: Serums are formulated with a higher concentration of active ingredients like antioxidants, vitamins, hyaluronic acid, or peptides. They're designed to target specific skincare concerns such as fine lines, wrinkles, dark spots, or hydration.
   • Texture: Serums typically have a lightweight, gel-like or liquid consistency that allows the active ingredients to penetrate deeply into the skin.
   • Usage: Serums are applied after cleansing and toning but before moisturizing. They're meant to be used sparingly due to their potency.

2. Moisturizer:

   • Purpose: Moisturizers are meant to hydrate and seal moisture into the skin. They contain a mix of humectants, emollients, and occlusives to prevent water loss and maintain the skin's barrier function.
   • Texture: Moisturizers have a creamier consistency and provide a protective layer on the skin's surface, helping to lock in moisture.
   • Usage: They're usually applied after serums to provide hydration and seal in the benefits of the serums. They can be used day and night.

In summary, serums are highly concentrated treatments targeting specific skin concerns, while moisturizers focus on hydrating the skin and maintaining its moisture balance. Depending on your skin's needs, you might use both a serum and a moisturizer in your skincare routine.
