Niacinamide (vitamin B3) is known for regulating Aquaporin-3 (AQP3), improving skin tone and texture, evening out skin tone, and may help reduce the appearance of acne. This natural compound is essential for the metabolism of proteins, carbohydrates, and fats in cells, and acts as a precursor in the synthesis of coenzymes NAD and NADP, which are involved in cellular energy production.
