The niacinamide (vitamin B3) is a versatile cosmetic active ingredient that helps to even skin tone, minimise pores, reinforce the skin barrier and control sebum. In concentrations of 2-10 %is suitable for a multitude of skin types and routines. We explain how it works, when to use it, which concentration to choose and how to integrate it easily.
What is niacinamide and how does it act on the skin?
Niacinamide, or vitamin B3, is a water-soluble molecule that, once applied to the skin, acts on several fronts:
- improves the function of the skin barrier by stimulating ceramide and lipid synthesis: reduces transepidermal water loss.
- regulates sebum production and helps to minimise the appearance of enlarged pores.
- acts as a mild anti-inflammatory: soothes redness, acne outbreaks or irritations. Druni
- helps to mitigate the hyperpigmentation by inhibiting melanin transfer to keratinocytes.
Proven benefits of niacinamide
Here are the key benefitswith concrete data:
| Benefit | What it does | Evidence / indication |
| Unification of tone / blemishes | Reduces visibility of dark spots and marks | Studies show improvements after 4-8 weeks with 2-5% of niacinamide. |
| Sebum and pore reduction | Regulates sebaceous gland and smoothes texture | "Regulates sebum production, reduces enlarged pores" according to specialists. |
| Barrier reinforcement / sensitive skin | Inhibits water loss and soothes reactive skin | "Improves hydration and strengthens the skin barrier". |
| Universal compatibility | Suitable for all skin types, even sensitive skin. | Review articles describe it as "versatile for almost all skin types". |
A useful fact for your readers: in marketed products it is normally in the range of 2 % to 10 % of concentration - more on this later.
How to use niacinamide correctly in your daily care routine
Here you have concrete steps to include it without problems:
- Cleaningmorning and/or evening, a good cleansing to remove any traces of cosmetics or pollution.
- Toner/lotion (optional)prepares the skin.
- Application of niacinamide:
- In the morning: after toner, before moisturising cream and sunscreen (very important).
- At night: can be used alone, or before a more potent active.
- In the morning: after toner, before moisturising cream and sunscreen (very important).
- Moisturiser and/or final treatment.
- Sunscreen the next day (without SPF there will be no optimal staining results).
Compatibilities and tips for niacinamide application
- It can be easily combined with hyaluronic acid or ceramides.
- Regarding Vitamin C: although it used to be said that it was not, today most experts consider it to be compatible in the same routine if the formulations allow (pH, texture) - however, if your skin is very reactive, alternate nights.
- With "stronger" actives such as retinol, AHA/BHA: it is recommended to start with niacinamide alone, and then introduce the aggressive actives.
Watch out, don't make these common mistakes:
- Expect "immediate results" - the skin works slowly.
- Put niacinamide in the last step (it must act before the moisturiser).
- Use very high concentration on skin that has never tolerated it → irritation.

Does niacinamide lighten the skin or "erase" blemishes?
It doesn't "erase" like a concealer, but it does visibly decreases the skin blemishes by inhibiting melanin transfer. Results appear after a few weeks of constant use.
Can I use niacinamide with vitamin C?
Yes, nowadays it is considered compatible if both formulas are well designed. If you are a beginner, you can alternate nights for safety.
How long does it take to see the result?
It depends on the problem: for a smoother skin/texture you may see improvements in the 4-8 weeks. For deeper stains maybe 12 weeks or more. Consistency is key.
What if it irritates my skin?
Lower the frequency or use lower concentration (e.g. 2-3 %). Do a patch test before full incorporation.
Is it suitable for pregnant or breastfeeding women?
Yes, niacinamide is one of the safest active ingredients in cosmetics topical. However, always consult your dermatologist for your specific case.
Is 10 % better than 5 %?
Not necessarily "better" for all. The higher the concentration, the greater the potential for effect y of irritation. If your skin is a novice, start lower (5 %) and then move up if you can tolerate it.
