Can Vitamin C and Vitamin B3 be used together?

Vitamin C and Vitamin B3 are both ingredients included at many cosmetic products due to its anti-aging, antioxidant and restorative properties, but are they as effective as everyone say?

And most importantly, can they be used together on the same product? or will it negatively affect the skin?

These questions come from voices that claim that both, ascorbic acid (Vitamin C) and Niacinamide (Vitamin B3,) are incompatible when used together. However, other studies claim that it is only a myth based on no actual evidence.

We know that these two ingredients have great benefits for our skin to make it look healthy and prevent the signs of aging. It is, therefore, very important to know whether or not we can use them together so we can multiply their benefits or whether we should settle for just one of them at a time.


Incompatibility of Vitamin C and Vitamin B3 in the same cosmetic. Myth or reality?

Fortunately, it's just a MYTH. To dismantle this false myth, we must go back to the first studies that were made on the 60s, and that advised against the mixture of these two vitamins because of a misinterpretation of the studies by part of some scientists. These studies, already outdated, said that the effectiveness of these two vitamins combined was very limited and, and also, it could produce a substance called nicotinic acid that causes redness being negative the care of our skin and recommending to the people not to mix these two vitamins in the same cream.

The reasons given by the study is that vitamin B3 (Niacinamide) needs an almost neutral pH to be stable and vitamin C (ascorbic acid) needs a low pH, i.e. an acid pH. And that both, combined at high temperature could react, producing nicotinic acid. This last argument is the key that makes this incompatibility only a myth.

As the study says, this incompatibility only occurs at high temperatures, something that under normal conditions doesn’t happen, not even leaving a cosmetic under the sun during the summer.

However, the study may have some reason about the problem of different pH requirements. If both need different pH and both are in the same formulation, it is obvious to realize that one of them will not be preserved at its ideal pH (because either we use the pH that suits one or the other). If this happens, the active ingredient that is badly preserved, will degrade and therefore stop working.

This last point is one of the reasons that led us to create Lesielle, and one of the advantages of our isolated formulation.  Since our active ingredients are always separate (isolated formulation), and each one of them is preserved in its ideal medium, there are not pH incompatibilities, and active ingredients cannot react because they are only mixed at the moment before the application. Like this, they can maintain all their properties and do not degrade because being mixed at a different pH.


Benefits of Vitamin C and Vitamin B3 

Both, Vitamin C and Vitamin B3 have magnificent properties for the care and protection of our skin. These two ingredients are considered one of the most effective cosmetic ingredients and, especially Vitamin B3, it is very compatible even with the most sensitive skins.  

Vitamin C, in the form of ascorbic acid or any some of its stabilized forms (such as magnesium ascorbyl phosphate), is a great antioxidant that protects us from the pollution, diminish shines and brighten the face as no other active ingredient does. Its effects are visible and provides an effective solution to care for our skin needs and show a good tone. 


Niacinamide or Vitamin B3 has restorative properties
that lead to the correction of dilated pores, fine lines and cares dull skin. It stimulates our skin to produce ceramides and other lipids improving the barrier function of our skin and fighting against external aggressions and maintaining good hydration. In fact, these two substances combined can be very effective in a daily skin care routine (normal, oily, dry and mixed skin) giving an anti-aging and antioxidant effect, removing sun spots and improving skin tone. 


At Lesielle we offer both active ingredients to allow everyone to create their customized product that fits their unique cutaneous needs. We only use opaque and airless containers that maintain the properties of the active ingredients ensuring the effectiveness of these two vitamins in your customized cream so you can obtain visible results in just a few weeks.
