Both are gentle, both work on dark marks and breakouts, and both show up in a lot of routines. So which one is for you? Often the answer is “it depends what’s bothering you most”.
Niacinamide: the all-rounder
Niacinamide is a form of vitamin B3. It’s easy-going and works for almost every skin type.
- Helps control oil and the look of large pores
- Calms redness and supports your skin barrier
- Fades dark marks slowly with steady use
Best for: oily or combination skin, shiny T-zones, and anyone starting out. Use it morning or night, after cleansing and before moisturiser.
Azelaic acid: the targeted one
Azelaic acid is a gentle acid that works on breakouts and uneven tone at the same time.
- Helps clear breakouts and keeps pores from clogging
- Fades dark marks and uneven patches
- Calms skin that flushes or turns red easily
Best for: breakouts with dark marks left behind, redness-prone skin, and stubborn uneven tone. It can tingle for the first week or two. Start every other night.
Can you use both?
Yes, and they work well together. A simple way:
| Morning | Night | |
|---|---|---|
| Step 1 | Cleanser | Cleanser |
| Step 2 | Niacinamide | Azelaic acid |
| Step 3 | Moisturiser | Moisturiser |
| Step 4 | Sunscreen |
Give any new product 6 to 8 weeks before deciding if it works, and add one at a time.
