Moisturizers VS Serums: What Makes Them Different?


Moisturizers and serums have similar qualities but can they be used interchangeably?

The answer is simply no. Although moisturizers and serums have similar benefits, such as promoting moisture retention, they help the skin in different ways. To find out what makes these types of products different, continue reading!


  • Serums are thinner and have a lighter consistency than most moisturizers.
  • Serums are comprised of smaller molecules and can penetrate the deep lipid 04_Dec14_elemis_eyes_176_v2.jpglayers of the skin – deeper than moisturizers.
  • Serums contain concentrated active ingredients (vitamins, minerals, botanicals, antioxidants, etc.) to help soothe, nourish, replenish and rejuvenate the skin.
  • Serums have more anti-aging benefits (firming, line smoothing, plumping, etc.) than moisturizers alone due to their penetrating qualities and high-quality active ingredients.
  • Serums should be used directly after cleansing and toning the skin in order to be absorbed into the skin effectively.
  • There is a wide array of serums on the market – some aid in brightening and youth-enhancing while others aid in pore size and acne prevention.
  • Our LEROSETT® Pore Minimizer, GUNILLA® Cell Rejuvenator, and LEROSETT® Healing Serum are all examples of active serums.


  • Moisturizers are thicker and creamier in consistency than serums.
  • 02_Dec14_elemis_moisturising_132_v3_648.jpgMoisturizers can be either emollient or occlusive.
  • Emollient moisturizers are absorbed into the skin quickly and contain humectants to help attract and lock in moisturizers, preventing moisture loss.
  • Applying an emollient moisturizer should be the final step in your skincare routine.
  • Some moisturizers do have added anti-aging ingredients such as our GUNILLA™ Deep Skin Moisturizer with Ceramides.
  • Our GUNILLA™ Deep Skin Moisturizer with Ceramides and our LEROSETT® Moisture Matte Clear Skin Moisturizer are examples of emollient moisturizers.
  • Occlusive moisturizers sit on top of the skin and take longer to be absorbed. For instance, mineral oil and Vaseline are occlusive moisturizers and are considered a fast solution for chapped lips/skin.
  • Occlusive moisturizers can clog pores if used long-term.
