Should You Use a Serum or Moisturizer?

Skin care is vital. Anything you can do to keep your skin looking healthy and flawless is worth doing. Whether you are applying serum or moisturizer, the undisputed fact is that both routines are advantageous to the skin. That being said, moisturizers and serums are both good for your skin. But what do these two skincare products do; and which do you need more?

Moisturizers are basically made to hydrate your skin. By moisturizing your skin, it is better equipped to seal in natural moisture produced by your body. While moisturizers also help in fixing specific conditions like aging and sun damage, their main function is to add moisture to the skin and keep it hydrated for long periods.

Serums¸ however, are designed to penetrate into the deeper layers of the skin to prevent the causes of aging and skin damage. Serums contain antioxidants, minerals, and vitamins that repair skin damage on a cellular level. This type of skincare product address specific skin issues and are very effective in enhancing skin smoothness, suppleness and radiance.


Serum or Moisturizer

You can find the differences between serum and moisturizers in their respective components and function. Here is a simple formula to break down their components.

Moisturizers = water + oil + waxes + actives.

Serums = water + oil + actives + peptides.

On closer inspection of these compositions, serum and moisturizers have a couple of differences; which are:

  • Serums don’t have ‘sealing’ components like moisturisers. They don’t moisturize or retain skin moisture.
  • Serums contain ‘peptides’ which infiltrate the deep layers of skin and enhance collagen production.
  • Serums have more ‘actives’ that deliver nutrients to layers of skin where moisturizers can’t reach.


How a Moisturiser Works

A moisturizer is a lotion or cream that is made of hydrating emollients that keep the skin hydrated. The molecules in a moisturizer are much bigger than serums which don’t allow them to penetrate the surface layer of the skin. Moisturizers simply form a moisturizing barrier on the skin.


How a Serum Works

Serums are intensive skincare products which do more work than moisturizers. Their lightweight properties allow them to penetrate the epidermis, injecting nutrients that combat free radicals, skin discoloration, scarring, aging and acne breakouts. Serums are very effective skincare products that combine the powers of peptides, antioxidants, hyaluronic acids and vitamin C which exfoliate, brighten and hydrate the skin at a fast pace.

Serums are skin-repair products. If you have damaged, scarred or sun-damaged skin, your best bet is to use a serum. Serums repair skin on a cellular level improving the skin’s firmness, brightness and smoothness while also reducing wrinkles and fine lines from within.

Should You Use a Serum or Moisturiser?

As we’ve previously established, serum repairs skin damage on a cellular level, while a moisturizer prevents the evaporation of moisture from the skin. Serums work more effectively than a moisturiser. Mostly, we use serums alone, morning and night, to address specific skin conditions. However, should you combine with moisturizers, they can seriously improve hydration in the skin.

Moisturizers are basically a must—everyone uses them. Serums, on the other hand, are important determinants of a successful skin care routine. If you’re above the age of 30, serum use can definitely combat the effects of aging and sun damage.

Serums are also quite flexible to use. For people with oily skin, serums are used alone. But for people with dry skin, serums are advised to be combined with moisturizers. Although for winter months and drier climates, moisturizers should be prioritized over serums. The skin finds it hard to cope with cold temperatures and drying winds and often gets dry in such seasons.


Here are some candid reasons to include the use of facial serums in your skin care routine:

  1. Brightens the Look of Dull Skin

The older you get, the more your skin starts to lose its youthful sheen. To maintain your skin’s radiance, you can apply serums to your skin. Serums have ingredients that illuminate the tone of your skin and stimulates cell production that keeps your skin healthy. Want to incorporate an anti-aging process into your skin care routine? Simply use your preferred serum to clean your skin twice daily, i.e. in the morning and at night, before bedtime.

  1. Minimizes Skin Discoloration

The bane of dark spots is one in which all human beings suffer. Daily exposure to UV rays from the sun, not to mention aging, can lead to discolorations in the skin. In other words: dark spots. Serums are very effective in glossing over the vivid appearances of dark spots. Apply your serum morning and night daily for best results. Also, don’t forget to apply sunscreen or SPF whenever you head out. You may reapply sunscreen every two hours, or immediately after swimming.

  1. Slows Aging Symptoms

Serums are very powerful anti-aging skincare products. You’ll need to use a serum that has hyaluronic acid (HA) as one of its main components. This ingredient, HA, is responsible for brightening the skin. Another important ingredient your serum should have is vitamin C. It is a very potent anti-aging vitamin. Your serum must also have vital antioxidants. For best results, apply serum morning and night before using your anti-aging moisturizer.

  1. Boost Collagen Production

As you age, your body produces less and less collagen which leads to dry skin and wrinkling. Serums have vitamins and minerals that penetrate the skin to stimulate the cells that produce collagen.  You can apply your preferred serum to delicate areas of your skin that are losing color and moisture.
