When To Use Face Serum
Face serums have become a must-have in modern skincare.
They are lightweight, fast-absorbing, and packed with powerful active ingredients that target specific skin concerns — like acne, pigmentation, aging, dullness, and dehydration.
But one question almost everyone has is:
“When should I use a serum?”
Using a serum at the right time is just as important as choosing the right serum.
Here’s a complete guide to help you understand when and how to use serums correctly.
What is a Serum?
A serum is a concentrated skincare product designed to deliver active ingredients deeper into your skin.
It usually has a thin, watery, or gel-like texture — making it easier for your skin to absorb.
Common serum types include:
- Vitamin C serum
- Hyaluronic acid serum
- Niacinamide serum
- Retinol serum
- Salicylic acid serum
- Brightening serums
- Anti-ageing serums
So, When Do You Use a Serum?
1. After Cleansing
Your serum should always be applied right after washing your face. Clean skin ensures that the active ingredients penetrate better.
✔ Start with a gentle cleanser
✔ Pat dry — don’t rub
✔ Use serum after facewash & toner
✔ Apply while your skin is still slightly damp for better absorption
This boosts absorption and effectiveness.
2. Before Moisturizer
Serums are lightweight and made to be layered under heavier skincare products.
Rule:
Cleanser → Toner → Serum → Moisturizer → Sunscreen
Moisturizer helps to “seal in” the serum and lock the ingredients into the skin.
3. Morning or Night? Depends on the Serum!
Not all serums are meant for the same time of day.
Here’s a breakdown:
Use in the Morning
- Vitamin C serum – Brightens skin, fights pigmentation, protects against pollution
- Niacinamide serum – Controls oil, strengthens skin barrier
- Hyaluronic acid serum – Adds hydration and plumpness
Morning serums work best when followed by sunscreen.
Use at Night
- Retinol serum – Anti-ageing, reduces fine lines, evens skin tone
- AHAs/BHAs (exfoliating serums) – Removes dead skin, unclogs pores
- Peptide serums – Repairs skin overnight
Night is the best time for stronger serums because your skin is in repair mode.
Use Both Morning & Night
(Some serums can be used twice daily)
- Hyaluronic acid
- Niacinamide (depending on concentration)
- Gentle brightening serums
Always check your skin’s tolerance and product instructions.
4. Use Serums Based on Skin Concerns
Every serum targets something specific.
Use the right one at the right time:
- For dullness: Vitamin C in the morning
- For dark spots: Niacinamide morning & night
- For acne: Salicylic acid at night
- For ageing: Retinol at night
- For dryness: Hyaluronic acid twice a day
5. How Much Serum Should You Use?
A little goes a long way.
Use 2–3 drops or a pea-sized amount.
Pat gently into your skin — do not rub aggressively.
6. When NOT to Use a Serum
Avoid serums if:
- Your skin is broken or irritated
- You have active burns, allergies, or infections
- You are using multiple strong actives together without guidance
Don’t mix:
- Vitamin C + AHAs/BHAs
- Retinol + AHAs/BHAs
- Retinol + Vitamin C (unless instructed)
Final Thoughts
Using a serum at the right time can completely transform your skincare routine.
Remember the simple rule:
Cleanser → Toner → Serum → Moisturizer → Sunscreen
Choose your serums based on your skin type and concerns, use them consistently, and let the ingredients work their magic.
