There are very few skin care ingredients that have been associated with words like “powerhouse,” “all-around ingredient” or “multitasker.” But Niacinamide (pronounced nie-uh-sin-uh-mide) is truly just that. It’s the one ingredient you’re probably missing, but should definitely be using.
Niacinamide, also known as vitamin B3, has been used in dermatology to improve skin health for years. So before you write this off as just another upcoming fad in skincare, know that it’s undergone clinical testing and established itself for being useful when applied topically—so it’s proven.
Niacinamide is great all year round, but especially in the winter (we’ll get to that in a second). Let’s get right into it...
3 Reasons You Should Incorporate Niacinamide Into Your Skincare Routine
Here are our top three reasons why you should be incorporating Niacinamide (B3) into your skincare routine.
1. Reduces Inflammation + Promotes Even Skin Tone
The Science: Niacinamide actively manages inflammation associated with acne and rosacea by improving the skin barrier. Plus, it increases the rate of skin healing and tissue regeneration.
The Results: It reduces the appearance of hyperpigmentation, redness, yellowing and blotchy skin spots for a clearer, more even skin tone (see ya, acne!).
2. Improves Hydration
The Science: This ingredient improves moisture content in the top layer of the skin by increasing the production of keratin, ceramide and fatty acids. It also encourages the production of natural emollients that can help the skin remain hydrated.
The Results: A glow and dewy, hydrated look you never thought possible? It’s yours!
3. Slows the Aging Process
The Science: Niacinamide decreases free radical damage associated with sun and pollutants. Even better? It reduces the rate of decline of enzymes in skin that influence the aging process.
The Results: Think of Vitamin B3 as a skincare miracle worker. It increases skin elasticity and smooths fine lines.
