What is the difference between serum and moisturiser?
Serums are more concentrated than moisturisers. They aid in hydration but are intended to penetrate deeply into the layers of the skin to deliver high concentrations of targeted active ingredients and treat a wider variety of skincare concerns. Serums are generally thinner than a moisturiser and are easily absorbed, making them perfect for layering.
Moisturisers help to fortify the surface of the skin and work to increase hydration to the outer layers, prevent water loss and seal in moisture. They strengthen the skin’s protective barrier and help prevent harmful bacteria and environmental factors, such as pollution, from entering the skin.
Moisturisers are thicker than serums, so they can help build a barrier on the skin. They can contain active ingredients, but do not penetrate as deeply as serums.
