15% Vitamin C and 10% Niacinamide Hyperpigmentation Treatment Set - Frequently Asked Questions

I read that you shouldn’t combine Vitamin C and Niacinamide because the combination can cause serious skin irritations?

This misconception is based on older research on how mixing Ascorbic Acid with Niacinamide can convert the latter into Niacin, which can cause skin inflammations.

In practice, Niacinamide is one of the most stable vitamins. There are specific studies* reporting test results of 10% Niacinamide solution being autoclaved in water at 120° without any degradation occurring for 20 minutes. These are extreme laboratory conditions that cannot be easily replicated in everyday life.

We always recommend, however, to stay out of the sun to avoid any skin irritations during hyperpigmentation treatments, as well as to preserve your skin.

I have sensitive skin. Can I use Vitamin C and Niacinamide together?

Yes, you can. However, we always recommend gradually introducing new treatments to avoid potential skin irritations.


How do you properly layer Vitamin C and Niacinamide?

Vitamin C is an unstable and sensitive molecule. To maximise its effectiveness, apply the Vitamin C on cleansed and dry skin, then wait for 5-10 minutes before applying Niacinamide.


How many times a day should you apply Vitamin C and Niacinamide?

Twice a day after cleansing your skin.
