FAQ:

Q: Can you use vitamin C and niacinamide together?

A: You can use Niacinamide and Vitamin C together and apply the solution to your skin. When Niacinamide and Vitamin C are mixed, the two ingredients recharge and repair the texture of the skin. They also reduce the size of the pores, thus boosting collagen and enhancing a youthful glow. Understand that even though you can mix the Niacinamide and Vitamin C, they will still produce a chemical reaction.

Q: Can vitamin C be used with niacinamide?

A: You can totally use Vitamin C and Niacinamide together. The chemical reactions they trigger are very slow or reversible so they can’t compromise their effectiveness. Reddit cosmetic chemist Stephen Alain Ko was the first to point out they can be used together.

Q: Does niacinamide really help prevent skin cancer?

A: Cancer: A study published in the New England Journal Of Medicine showed that niacinamide was effective at reducing the risk of developing skin cancers. Participants at high risk of developing skin cancer who took niacinamide over one year reduced their risk of basal cell carcinoma and squamous cell carcinoma by 23%.

Q: Can niacinamide cause liver damage as niacin can?

A: Niacinamide might harm the liver, especially when used in high doses. Taking niacinamide along with medication that might also harm the liver can increase the risk of liver damage. Do not take niacinamide if you are taking a medication that can harm the liver.
