Serum vs Moisturiser - Which One Should I Use?

We get asked that question a lot - check out the simple answer here.

"Serum or moisturiser - which one should I use?"

In short, the answer is: Both

Why? The role Serums and Moisturisers have on our skin is very different. Let me walk you through each.



Serums are like vitamins for our body, they are supplements to the skin. Everyone should be using a serum in their skin regime. It is the greatest addition to target your skin concerns with potent ingredients.

When do I use a serum?

Serums can be used everyday, morning and night after cleansing the face. A different serum can be used in the morning to the one you use at night time. For example Vitamin C is a great one to use in the daytime and then a firming serum at night to target concerns of ageing. Some serums should be used less frequently than every day or only at night time and other serums can be layered over one another, so please make sure to follow the guidance of your skin therapist.

A moisturiser is designed to protect your skin and prevent hydration loss during the day and help repair and rejuvenate your skin at night. The ingredients in a moisturiser form a barrier and coat the skin to lock in all the goodness that you have applied underneath (i.e. your serums).

What type of moisturiser is best for me?

This is a common question and I have an easy guide for you! As a general rule, we base the ideal moisturiser for your skin on when you notice an oil shine during the day.

If you experience an oil shine:

  • Before lunchtime: Look for a matte finish or oil-free moisturiser
  • Midday/early afternoon: A oil-free moisturiser is perfect
  • Late Afternoon: Opt for a medium weight moisturiser
  • Never: Your skin will be thirsty for the heaviest weight moisturiser
