Azelaic Acid vs Niacinamide: Which Is Better for Dark Spots?
Both fade dark spots, but they work differently. Here's how azelaic acid and niacinamide compare — and how to choose between them or combine them.
If you're dealing with dark spots or the marks acne leaves behind, you've probably seen both of these ingredients recommended. They're both well tolerated and both fade pigmentation — but they work in different ways and suit different people.
Example prices are for The Ordinary versions at Pakistani retailers in November 2026 (via Derma.pk). 15–20% azelaic acid creams are sold in pharmacies; ask a doctor before using these stronger creams.

|---|---|---|---|---|
| Azelaic acid | 10% (cosmetic) to 15–20% (pharmacy creams) | Rs 3,150 | Acne-prone, rosacea, sensitive | Stronger for dark spots and acne marks |

How does azelaic acid fade dark spots?
Azelaic acid slows tyrosinase, the enzyme pigment cells use to make melanin, and it acts most on overactive pigment cells — the ones causing dark spots — rather than on normal skin. It also kills acne bacteria and calms inflammation. That's why it's used for both acne and pigmentation, and why dermatologists often prescribe it for melasma and post-acne marks in brown skin.
Cosmetic serums usually contain 10%. Pharmacy creams contain 15–20% and are more effective but more likely to sting.
How does niacinamide fade dark spots?
Niacinamide works further along the process: it reduces how much pigment is transferred from pigment cells to the surrounding skin cells. It also strengthens the skin barrier, reduces redness and controls oil. Its effect on dark spots is real but gentler and slower than azelaic acid.
Which is better for dark spots: azelaic acid or niacinamide?
For stubborn spots and post-acne marks, azelaic acid is usually the stronger choice. For overall dullness and uneven tone, or if your skin is easily irritated, niacinamide is a comfortable place to start.
Because they work on different steps of pigment production, using both together often gives better results than either alone.
Can you use azelaic acid and niacinamide together?
Yes. A simple routine:
- Morning: niacinamide, then moisturiser, then sunscreen.
- Night: azelaic acid on dry skin, then moisturiser.
Neither ingredient makes your skin more sensitive to the sun, but you still need daily sunscreen — otherwise new pigment forms faster than you can fade it.
Who should choose which?
- Choose azelaic acid if you have post-acne marks, active breakouts, rosacea or melasma.
- Choose niacinamide if you're a beginner, have oily skin, or want gentle overall brightening.
- Use both if you have time and patience — and give it 8 to 12 weeks.

Frequently asked questions
Can I use azelaic acid and niacinamide together?
Yes, they're compatible. You can use niacinamide in the morning and azelaic acid at night, or apply niacinamide first and azelaic acid on top in the same routine.
Which is better for post-acne marks?
Azelaic acid tends to work better for the brown marks left after acne, and it also helps prevent new breakouts — so it treats the cause as well as the mark.
Does azelaic acid sting?
It can tingle or itch for the first week or two, especially at 15–20%. This usually settles. Start every other night and apply it to completely dry skin.
Is azelaic acid safe during pregnancy?
Azelaic acid is generally considered one of the safer options for pigmentation and acne in pregnancy, but always check with your doctor before starting any treatment.
