Vitamin B3 has two forms - nicotinic acid (niacin) and nicotinamide (niacinamide). It is primarily synthesized from the amino acid tryptophan, which is an essential amino acid obtained from dietary sources such as poultry, salmon, and red meat.

In the body, nicotinic acid is converted to nicotinamide, which is an important enzymatic cofactor. However, nicotinic acid can be overly irritating to the skin, so skincare products typically use niacinamide as the form of vitamin B3.

According to the latest cosmetic dermatology textbook "Cosmetic Dermatology: Products and Procedures" edited by the renowned scholar Zoe Diana Draelos and published in December 2021, recent research has shown that niacinamide has a wide range of beneficial effects for skin care.

The key to niacinamide's versatility is its excellent skin absorption, due to its small molecular size and non-ionic nature, which allows it to be effective in various formulations and vehicles.

A key formulation challenge with niacinamide is to prevent it from hydrolyzing into irritating nicotinic acid in the product. This requires high purity of the niacinamide raw material and careful formulation to minimize free acid contamination. Designing a well-formulated product is crucial to prevent negative reactions.
