We began this FAQ post on Niacinamide with two important questions. 

Are you familiar with the properties of Niacinamide?

And then a second question. If you know these amazing properties, what are you waiting for to use it?

Having clarified these two important issues, let’s continue the journey into Niacinamide that we started some time ago, before diving into the most common donde on the use of Niacinamide in skin care products.

We were saying that if the most experienced skincare addict had to choose just one ingredient to take on a desert island, they would choose Niacinamide. Why?  For two reasons: its totally natural composition and the fact that it contains so many benefits, each one more incredible than the other.

Once we have defined what Niacinamide is and recalled what its properties are for the skin, we are going to answer many questions about the use of Niacinamide and dispel some popular beliefs that are completely wrong. Because it has to be said that yes, whatever your skin type, resorting to Niacinamide-based cosmetics means being able to ward off multiple problems thanks to a single ingredient, which is both versatile and effective at maximum power.

That’s what we’re going to talk about today: 

  • What is Niacinamide?
  • What Are the Surprising Properties of Niacinamide?
  • Conclusions

What is Niacinamide?

The first question about Niacinamide should really be about its composition. Good. As we have written in our guide to the ’use of Niacinamide cosmetics, this is nothing other than a derivative of vitamin B3, whose chemical name is Niacin.

Niacinamide is not synthesized directly by the skin and therefore must be taken through foods that contain it such as white meat, spinach, peanuts, beef liver, brewer’s yeast or certain fish such as salmon, swordfish and tuna. In addition it can be taken through supplements or through topical application to the skin. 

What Are the Surprising Properties of Niacinamide?

The second frequently asked question about Niacinamide is about its properties, which many compare to real superpowers. Its fame as a WOW ingredient stems from the fact that this substance gives the skin a youthful appearance. 

For the sake of convenience, the effects can be grouped into three distinct categories, based on the benefits they provide: Purifying, Nourishing, Enlightening effects. 

Let’s look at them in detail.

This is one of the first questions about Niacinamide that is asked, especially by those with sensitive skin that is prone to irritation. 

The answer to this question is “generally no”, in principle there are no side effects from direct application. It must be said that, given its vasodilating action, Niacinamide on the skin at very high concentrations could lead to temporary redness due to the accumulation of blood on the surface. 

However, this is true for formulations that use concentrations of 1.5%, which can reach up to 10% for more accustomed skins. It must be said that these concentrations are really very high and almost impossible to find.

Niacinamide in cosmetics has no side effects because it mixes easily with any active ingredient without causing irritation. This is mainly due to the fact that the Niacinamide contained in cosmetics is not present in such large doses as to cause reactions. 

I Have an Extremely Dry Skin. Can I use Niacinamide?

Absolutely. Just by virtue of its infinite number of benefits, Niacinamide is the number one ingredient for reducing dryness and itchiness.

I have super sensitive skin. Could Niacinamide Cause Irritation? 

Niacinamide is tolerated by most sensitive skin types. But if you’re unsure, the rule of thumb is still the same. Run a patch test on a small area of your face and see what happens. We take this opportunity to remind you in this case, to always use a few cosmetics, perhaps with a minimal list of ingredients, so you can always monitor the situation.

I have oily or combination skin. Will it help me to apply Niacinamide? 

Let me put it this way. If you have Oily or Combination skin, Niacinamide should have its own place in your routine. In fact, it regulates the production of sebum. This results in less enlarged pores and healthier skin. Plus, it eliminates acne scars and blemishes. So what do you say, are you in?

No. Niacinamide is not a photosensitizing active. This means that you can safely expose yourself to the sun without fear of developing blemishes or sunspots. What’s more, among the characteristics of Niacinamide is precisely that of eliminating spots, as well as acne scars.

Is it true that Niacinamide is one of the Actives that can be more easily mixed with other ingredients to trigger virtuous effects?
