Ingredient to Know: Niacinamide (Vitamin B3)
Seen the word Niacinamide everywhere recently but not totally sure what it is - or if it’s right for you?
We’re here to fill you in on everything you need to know about this trending active ingredient. We’ll be covering what Niacinamide is, how to use it as part of your regime and why it’s so amazing for your skin.
What is Niacinamide?
Niacinamide is a form of a water-soluble vitamin found naturally in the body, one that contributes to your overall wellbeing.
It plays an important part in keeping your cells functioning normally, as well as supporting your skin health.
The Simple truth
Nicinamide is an active ingredient that gives you multiple skin benefits in one - without causing irritation.
You’ll get this vitamin through your diet in the form of things like eggs and leafy green veggies, but topical Niacinamide is also a great way to experience some of this active ingredient’s skin benefits.
Is Niacinamide the same as Vitamin B3?
Yes, Niacinamide is one of the different forms of Vitamin B3. You might also see it referred to as Nicotinamide.
While it may sound very similar to Niacin, they’re technically different types of the same vitamin.
Both forms are safe to use, but you’re more likely to see Niacinamide listed as an ingredient in products.
One key benefit of Niacinamide is that it’s considered to be absorbed well, which makes it perfect for use in skincare.
What is Niacinamide good for?
Topical Niacinamide is famed for its ability to tackle a whole host of different skin needs without causing irritation.
Whether you're looking to make your skin tone look more even, tackle the first signs of ageing or get more control over breakouts, pretty much everyone can benefit from adding Niacinamide into their routine.
Some of the many Niacinamide skin benefits include:
- Balances oil production
- Minimises the appearance of pores
- Softens the look of fine lines
- Evens skin tone
- Makes skin feel firmer
- Helps tackle breakouts
- Supports skin barrier function
- Reduces moisture loss
- Improves skin elasticity
- Soothes redness

Is it ok to use Niacinamide every day?
Absolutely, Niacinamide is an ingredient that’s gentle enough to use daily. In fact, we recommend that you use it as part of both your morning and evening routines to get the best results.
When to use Niacinamide?
We think that the most effective way to use Niacinamide is in serum form. That’s because you get a more concentrated level of this multi-tasking active ingredient.
Plus, it's so lightweight that it penetrates through the skin easily, delivering all of those incredible benefits deeper.
If you’re new to using serums, then all you need to do to use our Booster Serum is smooth a few drops onto your skin after cleansing in the morning and evening.
Then, just follow with your favourite moisturiser. Don’t forget to use one with SPF if it’s in the beginning of the day to help give your skin some essential protection against UV rays.
How long does it take for Niacinamide to work on your skin?
Everyone’s skin is different, of course, but try using a Niacinamide Serum consistently twice a day for a few weeks and you’ll start to notice a difference in things like your skin tone and texture.
Can all skin types use Niacinamide?
Yes, one of the best things about Niacinamide is that it’s gentle enough for all skin types without having to worry about experiencing a potential side effect.
Like all Simple® products, our 10% Niacinamide (Vitamin B3) Booster Serum has been developed with sensitive skin in mind. Which means no perfume, colour or harsh chemicals either.
It’s also blended with 1% Vitamin B5, which helps keep skin hydrated, soft and smooth.
Plus, it’s vegan and cruelty-free certified by PETA, so it fits with your values as well as your regime.

Is Niacinamide or Hyaluronic Acid better?
Both Niacinamide and Hyaluronic Acid are equally amazing active ingredients that we recommend including in your skincare regime.
Depending on your skin’s needs, you might choose to just use one. However, combining Niacinamide and Hyaluronic Acid helps boost their effectiveness. It’s also a way to boost hydration, so it’s ideal if you have dry skin.
You can either blend them together and apply before your moisturiser or alternate between each different formula – see what works best for your skin.
