Hi! Welcome to Maelove.
Today we answer the question, can I use Vitamin C and Niacinamide together in my skincare routine?
The answer is yes. You may have heard not to mix these 2 ingredients together, but let me explain WHY you can most definitely use them both in your skincare routine.
If you’re new here, my name is Jackie and I’m the CEO and Chief Product Obsessor at Maelove.

Now, when you’re making a skincare formulation, like we do at Maelove, there is a reason NOT to combine vitamin C and niacinamide into a single product. Why is that you ask?
First of all, in most cases, the Vitamin C you’d find used in skincare products is ascorbic acid. Or L-ascorbic acid to be more specific although on ingredient labeling you’d see just “ascorbic acid” because that’s the official recognized ingredient term by INCI. I-N-C-I which is international standards in cosmetic ingredient labeling.
If a skincare product says it contains Vitamin C, probably 95 out of 100 times, it’s ascorbic acid. This is because ascorbic acid is the most widely used type of Vitamin C as it’s the most researched and proven form of Vitamin C.
Ascorbic acid is water soluble, which is why you usually find it in a serum form but it has to be formulated very specifically for it to actually get past your skin barrier and into your skin in significant amounts.
Ascorbic acid should be formulated to be pretty acidic - in pH 3.5 or lower and optimally at 10% or higher concentration. Ideally you also want to see it formulated with both Vitamin E and Ferulic Acid. This is because a study by Lin and colleagues in 2005 showed that if you add antioxidants Vitamin E and Ferulic acid to Vitamin C, this not only improves the stability of Vitamin C, but it also increases the photoprotective ability of Vitamin C by eightfold compared to Vitamin C alone
On the other hand, Niacinamide should ideally be formulated between a pH of 4 and 6 Why? Because outside of this pH range, Niacinamide is more likely to break down into Niacin which can be irritating to the skin.
