What Are Face Serums?

What Are Face Serums?

Any good skincare routine should include the staples: cleansers, moisturizers, serums, and SPF. Serums are the cornerstone of a solid routine and can do almost anything to improve the skin. These concentrated skincare elixirs are a must for tackling your most pressing skincare needs and doing the heavy lifting and choosing the right one can make all the difference in good and great skin. Ahead, we break down everything there is to know about using a facial serum and how to find the best face serum.


Despite all the skincare educational content out there, a major question remains: What is face serum, and what does a serum do for your face? From adding moisture to providing beneficial active ingredients and skin-friendly nutrients, serums can target a specific need. As a key step in building a skincare routine, serums often pack a more powerful punch compared to lesser potent products.


Lightweight serums typically contain active ingredients in high doses, including vitamins A, C, and E, glycolic, kojic, lactic, salicylic, and ferulic acids, peptides, resveratrol, hyaluronic acids, niacinamide, and retinol. While some may mistake a serum for a moisturizer, the two are entirely different. A serum for the face is far more than yet more potent. It is often used to address a specific skin concern, such as wrinkles, acne, or hyperpigmentation, depending on the main ingredients in the formulation. Since the active ingredients are typically in larger amounts and higher doses, they can better penetrate the skin for more visible results.


Different Types of Face Serums

  • Anti-aging serums: stimulate collagen and elastin to help fight the common signs of aging and defend against free radical damage 
  • Discoloration serums: brighten the skin to improve its overall tone 
  • Hydrating serums: add moisture to the skin for a younger, plumper look 
  • Acne serums: shrink pimples and diminish acne scars 
  • Retexturizing serums: improve the skin’s overall texture and appearance 

    The Key Ingredients in Face Serums

    Many different ingredients have made their way into face serums, some of which you might recognize from other skincare products. Commonly used active ingredients in serums typically include: 

    • RetinolRetinol is known for its anti-aging properties. It helps promote collagen production, speeds up cell turnover, and can also reduce the appearance of fine lines and wrinkles. Retinol is super effective against acne by preventing the buildup of dead skin and clogged pores.  
    • Vitamin CVitamin C (also known as L-Ascorbic acid) is a powerhouse antioxidant that does it all. Not only can vitamin C defend the skin against free radical damage, but it also helps stimulate collagen, brighten the skin, and improve the skin’s overall tone and appearance. 
    • Hyaluronic acidA staple moisturizing ingredient, it holds up to 1,000 times its weight in water, making it an excellent hydrating agent. By hydrating the skin, it works to plump up fine lines and wrinkles for younger-looking skin.
