Niacinamide Serums: Which Strength Should You Buy? (8 Compared)
Last reviewed: November 2026. Affiliate links below: as an Amazon Associate we earn from qualifying purchases.
Short answer: For most people, a 10% niacinamide serum is the right place to start: The Ordinary 10% + Zinc for a basic routine, Good Molecules if you want a minimal formula, or La Roche-Posay Mela B3 for dark marks. Higher strengths (12 to 20%) are not automatically better and are more likely to irritate, so patch test first.
Niacinamide is vitamin B3 in skincare form. It is used for visible pores, uneven tone, oiliness and fine lines. Here is how the eight serums differ and how to avoid the common mistake of starting too strong.

How to choose your strength
- Start at 5 to 10%. A review of the research notes tests found no stinging up to 10% and no irritation up to 5%.
- Read the label. Some listings do not state the percentage.
- Match to a goal. Pores and oil: plain niacinamide with or without zinc. Dark marks: look at a formula built for pigmentation. Dry or sensitive: a hydrating or soothing formula.
- Fragrance-free if you are sensitive.
- Patch test. Cleveland Clinic suggests applying a little on your forearm and waiting 24 hours.
What the research shows
In a published double-blind study, topical niacinamide reduced the look of fine lines, dark spots, blotchiness and sallowness. Reviews describe it as well tolerated, but also note that many studies are small or short. Results appear over weeks, not days.
Serum-by-serum notes
1. The Ordinary Niacinamide 10% + Zinc 1% Serum
Verdict: Best basic pick. The classic 10% niacinamide with 1% zinc, in a light gel. It has no added soothing or brightening actives, which makes it easy to judge how your skin reacts.
- Listing details: 30 ml; fragrance-free per the listing
- Good for: Normal to oily skin and first-time niacinamide users.
- Keep in mind: Some people find it pills (rolls into flakes) under heavy moisturizer.
2. Tree of Life Niacinamide Serum for Face
Verdict: Value size, check the label. A larger 60 ml bottle with a hydrating base. The listing does not clearly state the niacinamide percentage, so look at the label before treating it as a 10% product.
- Listing details: 60 ml; hydrating base with botanical extracts per the listing
- Good for: People who go through a lot of serum.
- Keep in mind: Ingredients may vary by batch, and some versions may contain fragrance.
3. Good Molecules Niacinamide Serum 10%
Verdict: Best minimalist 10%. A short ingredient list built around 10% niacinamide. It is a good choice if you want to avoid extras and keep a simple routine.
- Listing details: 30 ml (1 fl oz); described as non-comedogenic and fast absorbing
- Good for: People who prefer minimal formulas.
- Keep in mind: No other actives, and a smaller bottle for the price.
4. SKIN1004 Tone Balancing Capsule Ampoule
Verdict: Gentler multi-ingredient option. Pairs niacinamide with centella asiatica for soothing and tranexamic acid, which is marketed for uneven tone. The percentage of niacinamide is not stated on the listing.
- Listing details: 100 ml; hydrating, lightweight texture
- Good for: People who want a soothing formula rather than a high percentage.
- Keep in mind: More ingredients mean more chances of a reaction; patch test.
5. La Roche-Posay Mela B3 Dark Spot Face Serum
Verdict: Best for dark marks. Combines 10% niacinamide with Melasyl, a patented ingredient the brand positions for dark spots. Marks fade slowly, so expect to use it for weeks to months.
- Listing details: 30 ml (1 oz); light, non-greasy texture per the listing
- Good for: People targeting post-acne marks or uneven tone.
- Keep in mind: Premium price; results take time.
6. Eva Naturals Niacinamide 12% Serum with Zinc & Hyaluronic Acid
Verdict: Stronger, with hydration. A 12% serum with hyaluronic acid added for hydration and zinc. That is slightly above the usual 10%, so introduce it slowly.
- Listing details: 60 ml (2 fl oz)
- Good for: Oily or combination skin used to active serums.
- Keep in mind: Higher concentration can irritate sensitive skin.
7. medicube TXA & Niacinamide 15% Glow Serum
Verdict: High-strength, introduce slowly. Pairs 15% niacinamide with 5% tranexamic acid, aimed at dark spots. This is a potent combination; start a few times a week, not daily.
- Listing details: 30 ml (1.01 fl oz)
- Good for: Experienced users of active serums.
- Keep in mind: High actives can irritate sensitive skin.
8. Paula's Choice CLINICAL 20% Niacinamide Serum
Verdict: Highest strength, not for beginners. A 20% niacinamide serum in a small bottle. Percentages this high are not necessarily more effective and are more likely to irritate, so this is for people who already tolerate lower strengths.
- Listing details: 20 ml (0.67 fl oz); fragrance-free per the listing
- Good for: People who have already used 10% comfortably.
- Keep in mind: Higher risk of irritation and a small bottle for the price.
Who should skip it or go slowly
- Very sensitive, eczema-prone or broken skin. Ask a dermatologist first.
- Anyone who has had a reaction to niacinamide or a similar ingredient.
- People who are pregnant or breastfeeding and are considering formulas with added actives such as tranexamic acid should check with their doctor.
- Anyone with a rash or skin changes that do not clear up. See a clinician rather than layering products.
How to use niacinamide safely
Cleveland Clinic says niacinamide is generally gentle, but can rarely cause allergic reaction, itching, mild burning or redness. Start every other day, apply to clean skin before moisturizer, and use sunscreen in the daytime. If irritation appears, stop and give your skin a break.
Niacinamide FAQ
Is 10% niacinamide enough?
For most people, yes. It is the most common strength and sits near the level where studies reported good tolerability. Higher strengths may help some people but raise the chance of irritation.
Can I use niacinamide every day?
Most people can, once they have patch tested and built up. Start a few times a week.
Can I use niacinamide with vitamin C or retinol?
Many people do, usually in a routine that starts slowly. If your skin gets irritated, use them at different times of day or on alternate days.
How long until I see results?
Studies typically run for several weeks to months. Do not expect overnight change.
Does niacinamide help acne?
Reviews describe topical niacinamide as helpful for acne in some studies, but it is not a replacement for medical acne treatment.
