A practical guide to niacinamide
/

Reading time: 5 minutes
Niacinamide is vitamin B3. It is one of the few actives that suits almost every skin type, and it works well alongside retinal, vitamin C and acids. That makes it a good first active for anyone building a routine.
What it does
- Less shine: helps skin produce less visible oil through the day.
- Smaller-looking pores over several weeks.
- More even tone: fades the look of post-blemish marks.
- Stronger barrier: helps skin hold on to water better.
2% or 10%?
| Strength | Role | Where you find it | Best for |
|---|---|---|---|
| 2 to 5% | Support ingredient, working in the background | Rice Water Essence, Daily Gel Cream | Every skin type |
| 10% | The main event | Niacinamide 10 Serum | Oily and combination skin that wants less shine and smoother-looking pores |
Higher is not always better
Some people feel a brief warmth or see mild redness at 10%. If that happens, use the serum once a day for two weeks before moving to twice.
How long it takes
| Result | When to expect it |
|---|---|
| Shine control | Within days |
| Pores and tone | Eight to twelve weeks of daily use |
Give it time. Judge pores and tone after three months of daily use, not three weeks.
What to pair it with
- Morning: next to Vitamin C 15 Serum.
- Night: next to Retinal 0.1 Night Serum.
The old advice to keep niacinamide and vitamin C apart came from tests on pure, unstable ingredients at high heat, and it does not apply to modern formulas.
A simple morning
- Cloud Gel Cleanser
- Niacinamide 10 Serum
- Daily Gel Cream
- Daily Sheer Fluid SPF 50
Frequently asked questions
Can I use niacinamide twice a day?
Yes, once your skin is used to it. Start once a day at 10% if your skin is reactive.
Is niacinamide safe with retinal?
Yes. They pair well, and niacinamide's barrier support can make retinal easier to tolerate.
Do I need the serum if my moisturizer already has niacinamide?
Not always. A 2 to 5% level supports skin every day. Add the 10% serum if you want more visible change in shine and pores.
