Vitamin B3 or niacinamide is a nutrient essential for health owing to its conversion to the coenzyme nicotinamide adenine dinucleotide (NAD). NAD is utilised as a catalyst by more than 400 enzymes in the body, and along with its active form NADP; is required in most metabolic processes of aerobic metabolism. It is especially important in transferring potential energy from fats, carbohydrates and proteins to adenosine triphosphate (ATP), and also has function as an antioxidant and promoter of gene integrity and expression.
However when applied topically, niacinamide helps to lock in moisture and act as an anti-inflammatory and antioxidant, preventing environmental damage and inflammation. As such vitamin B may help to treat skin conditions such as eczema and acne. Furthermore, topical vitamin B:
Helps to increase keratin – a structural protein found in skin, hair and nails
Improves the skin barrier, helping to retain moisture and prevent dehydration
Minimise redness and irritation
Minimise the appearance of pores and regulate oil production
Protect again sun damage and oxidative stress i.e. pollutants and toxins
Minimise fine lines and wrinkles, and improve pigmentation by aiding in increased collagen production
