Serum vs Toner: What’s the Difference and Do You Need Both?
Updated November 1, 2026
A toner is a watery liquid used after cleansing, often to prepare the skin or add a light layer of hydration. A serum is a more concentrated product built around specific active ingredients, used after cleansing (and after toner, if you use one). You don't need both. A simple routine can go cleanser, serum, moisturiser, and sunscreen in the morning, with toner as an optional extra.
Serum vs toner at a glance
| Toner | Serum | |
|---|---|---|
| Texture | Very watery, liquid | Watery to slightly thick, used in drops |
| Usual job | Follows cleansing; often adds light hydration or prepares skin for the next steps | Carries one or more main active ingredients |
| How much | Applied with hands or a cotton pad across the face | A few drops for the whole face |
| Step | Right after cleansing | After cleansing, or after toner |
| Required? | Optional | Optional, but it’s where the main actives usually are |
Products called "toner" vary a lot. Some are simple watery hydrators; others contain actives like acids. Always read the ingredient list rather than judging by the name.
What a toner usually does
Toners started as a way to finish cleansing. Today, many are light, watery products that leave a thin layer of humectants (water-attracting ingredients) on the skin before the next step. Some contain exfoliating acids, which is something to know before you combine them with other actives.
What a serum usually does
A serum is built around active ingredients at a stated strength. Epidora Niacinamide 10% + Zinc PCA 1% Serum, for example, has niacinamide (10%) and Zinc PCA as its main actives, with aloe vera and pullulan as supporting ingredients. It is made for oily and combination skin. Its main active, niacinamide, has been studied for facial oil (see What Is Niacinamide?). To learn about each ingredient, read Niacinamide and Zinc Serum Benefits.
Signs a product is really a serum or a toner
- Look at how it’s used. Toners are usually applied in a larger amount, by hand or pad. Serums are used a few drops at a time.
- Look at what’s named on the front. A serum usually names its main actives and their strengths. A toner often doesn’t.
- Look at the ingredient list. If a toner lists exfoliating acids, count it as an active step and plan the rest of the routine around it.
Which to pick, by skin type
There is no single right answer. Here’s a simple way to decide:
- Oily skin: if you want one extra step, a serum made for oily skin fits most routines. A toner is optional.
- Combination skin: the same as oily skin; a serum across the whole face, then moisturiser adjusted by zone. See Skincare Routine for Combination Skin.
- Dry skin: a hydrating toner can add a light layer before moisturiser, if you like the feel. Choose a serum made for your skin type.
- Already using a toner you like? Keep it. Apply it right after cleansing, then the serum.
- Using an acid toner? Introduce it separately from a new serum, and avoid strong acids alongside a niacinamide serum at first.
How to layer them if you use both
- Cleanse.
- Toner, patted or swept on.
- Serum, 2–3 drops, patted in.
- Moisturiser.
- Sunscreen, in the morning, as the last step.

Mistakes to avoid
- Assuming a toner replaces a serum, or the other way round. They usually do different jobs.
- Using several active products at once. One new product at a time.
- Using lots of serum to make up for skipping toner. 2–3 drops are enough.
- Choosing by name alone. Read the ingredient list.
- Skipping moisturiser because you used a hydrating toner. Keep the moisturiser step.
Pairs with
- Epidora Niacinamide 10% + Zinc PCA 1% Serum: the serum step, morning and night.
- Epidora Barrier Repair Moisturiser: after the serum.
- Epidora Sunscreen: last, in the morning.

Precautions
Epidora serum contains fragrance. Keep away from eyes. Stop use if redness lasts. Avoid any product if you are allergic to a listed ingredient. See a doctor if a skin problem is persistent, painful, spreading or getting worse.
Patch test first: try a small amount on the side of your neck or behind the ear for 24–48 hours before using it on your face.
Frequently asked questions
Do I need a toner if I use a serum? No. Toner is optional.
Does toner go before or after serum? Before. Cleanser, toner, serum, moisturiser.
Can I use my serum on a cotton pad like a toner? No. Use 2–3 drops on your fingertips and pat them in.
Can I skip both? Yes. A cleanser, moisturiser and sunscreen make a simple base. A serum is the step to add for specific actives.
