Niacinamide, also known as vitamin B3, is a common skin care ingredient that can be beneficial for the skin. However, it is possible for niacinamide to worsen skin in some cases. Studies have shown that people with sensitive skin may be more likely to experience irritation from niacinamide. Additionally, it is possible for people to become sensitized to niacinamide over time, leading to worsening skin. It is important to start with a small amount of niacinamide and increase slowly to avoid irritation or other skin issues.

Can niacinamide damage your skin?

There is limited research regarding the potential side effects of niacinamide on the skin. While it is generally considered safe for most people, some people may experience skin irritation, redness, or a burning sensation after application. It is always best to speak to a qualified healthcare professional before using any topical skin care product. Additionally, be sure to follow the instructions on the product label and discontinue use if any signs of irritation occur.
