Serum vs Moisturiser: What’s the Difference & Which One Does Your Skin Really Need?


If you’ve ever built a skincare routine, you’ve probably wondered: Do I need both a serum and a moisturiser?

They may look similar, but they do completely different jobs and using them correctly can transform your skin.

Here’s a simple, beginner-friendly guide to help you understand the difference and choose what works best for your skin.

What Is a Serum?

A serum is a lightweight, fast-absorbing liquid packed with high-potency active ingredients.
It targets specific skin concerns such as:

  • Dullness

  • Dark spots & pigmentation

  • Acne marks

  • Uneven skin tone

  • Dehydration

  • Fine lines

Why Serums Work So Well

  • They have smaller molecules, which penetrate deeper into the skin.

  • They deliver targeted results, making them great for glow, hydration, acne, or anti-aging.

  • They show visible improvements faster than most skincare products.

Popular Types of Serums

  • Vitamin C serum – for glow & pigmentation

  • Niacinamide serum – for pores & oil balance

  • Hyaluronic Acid serum – for deep hydration

  • Retinol serum – for fine lines & texture

If you want fast results, a serum is your go-to.

What Is a Moisturiser?

A moisturiser keeps your skin soft, hydrated, and protected.
It acts like a comfortable barrier that locks moisture in and prevents dryness.

Why Moisturising Is Essential

  • Keeps the skin barrier healthy

  • Reduces dryness, tightness, and irritation

  • Locks in hydration from your serum

  • Helps maintain smooth, glowing skin

Types of Moisturisers

  • Gel moisturiser – for oily/combination skin

  • Cream moisturiser – for dry and sensitive skin

  • Water-based moisturiser – lightweight and perfect for humid weather

  • Barrier creams – for repairing damaged or sensitive skin

Even if your skin is oily, skipping moisturiser can make it produce more oil so moisturising is non-negotiable.

They don’t replace each other they work together.

Do You Need Both Serum and Moisturiser?

Yes — most skin types benefit from using both.

  • The serum gives your skin treatment.

  • The moisturiser locks it in and keeps your skin hydrated.

Using only a serum can leave the skin dry.
Using only a moisturiser may not give targeted results.

Think of it like:
Serum = nutrients
Moisturiser = protection

How to Layer Them Correctly

  1. Cleanse your face

  2. Apply your serum

  3. Seal it with a moisturiser

  4. Use sunscreen during the day

This routine works for oily, dry, combination, and sensitive skin.

Which One Should You Choose First?

Choose based on your main skin goal:

If you want glow

→ Use a Vitamin C serum + lightweight moisturiser

If you want smaller-looking pores

→ Use Niacinamide serum + oil-free moisturiser

If your skin feels dry or tight

→ Use Hyaluronic serum + rich cream moisturiser

If you want anti-aging benefits

→ Use Retinol serum (night only) + barrier-repair moisturiser

Serums and moisturisers are not competitors they are teammates.
A serum targets your skin concerns, while a moisturiser locks in hydration and keeps your skin protected.

When used together, they make your skincare routine more powerful, balanced, and effective helping you achieve smoother, brighter, healthier-looking skin.
