Niacinamide is a form of vitamin B3 that is used in skincare products due to its many benefits. However, some people may want to look for alternative names for this ingredient when reading labels or shopping for products. Fortunately, there are several synonyms for niacinamide that may be helpful. These include nicotinamide, nicotinic acid amide, 3-pyridinecarboxamide, and vitamin PP. While these words may sound complex, they all refer to the same ingredient and can help consumers identify products that contain niacinamide without confusion.
