✨ Niacinamide in Skincare: Why This Powerhouse Ingredient Deserves a Spot in Your Routine

If you’re on a mission to achieve healthier, clearer, and more radiant skin, niacinamide should be at the top of your skincare ingredient list. Also known as Vitamin B3, niacinamide is a multitasking active loved by dermatologists and beauty experts for its wide range of benefits.

What is Niacinamide?

Niacinamide is a water-soluble vitamin that works with your skin to:

Improve uneven skin tone
Soften fine lines and wrinkles
Minimize enlarged pores
Strengthen the skin barrier
Reduce inflammation and redness
Regulate sebum production

Unlike some actives that can cause sensitivity, niacinamide is well-tolerated by most skin types—including sensitive, oily, acne-prone, and mature skin.

The European Food Safety Authority (EFSA) issued its assessment on 26 September 2023, confirming that nicotinic acid and niacinamide continue to be considered safe for all animal species, for consumers, and for the environment when applied under currently authorized conditions.

EFSA also reaffirmed that both substances are reliable sources of niacin in animal feed. While they are not irritating to the skin or likely to cause skin sensitization, they can be irritating to the eyes, and inhalation exposure may occur during handling or processing. No additional post-market surveillance measures were deemed necessary beyond standard regulatory oversight.

Key Benefits of Niacinamide

✅ Brightens and Evens Out Skin Tone

Niacinamide helps reduce hyperpigmentation and dark spots, making it ideal for dull or uneven complexions.

✅ Fights Acne and Redness

Its anti-inflammatory properties calm breakouts and soothe irritation. It also regulates oil production, preventing clogged pores and congestion.

✅ Strengthens Skin Barrier

Niacinamide supports ceramide production, fortifying your skin’s moisture barrier to prevent water loss.

✅ Anti-Aging Power

Regular use can reduce the appearance of fine lines, improve skin elasticity, and smooth texture for a youthful look.

How to Use Niacinamide

You’ll find niacinamide in serums, moisturizers, and toners. For best results:

Use daily, morning and night, after cleansing and before heavier creams.
Combine with hyaluronic acid for hydration or retinol for enhanced anti-aging benefits.
Avoid layering with pure vitamin C (ascorbic acid) unless formulated together.
