What Is Niacinamide?
Benefits for Skin, Pigmentation, Redness & Barrier Repair

Niacinamide has become one of the most searched skincare ingredients globally. From “niacinamide serum for pigmentation” to “does niacinamide help with redness?” and “is niacinamide good for sensitive skin?”, interest continues to grow.

But beyond the trend, why is niacinamide so consistently recommended by dermatologists and cosmetic physicians?

At Rejuvaus, niacinamide is not used as a marketing hero ingredient. It is used as a structural ingredient, one that supports how skin functions.

This article explains what niacinamide is, how it works in the skin, its benefits for pigmentation, acne, redness and enlarged pores, and why formulation quality matters more than percentage alone.

What Is Niacinamide?

Niacinamide is a biologically active form of Vitamin B3, an essential nutrient involved in cellular energy production and DNA repair.

In skincare, niacinamide supports:

Hydration retention

Inflammation control

• 
  Fewer products
• 
  Better tolerance
• 
  Multi-functional performance
• 
  Long-term barrier support

Niacinamide delivers on all four.

It supports several biological pathways simultaneously, rather than targeting just one symptom. This makes it foundational in professional-grade formulations.

• 
  Stronger Skin Barrier.
• Niacinamide stimulates ceramide production in the stratum corneum. Ceramides are essential lipids that reduce transepidermal water loss and improve resilience.
• 
  Reduced Redness and Inflammation.
  
• Niacinamide modulates inflammatory pathways, helping calm visible redness and irritation.
• 
  Pigmentation Support.
• Niacinamide reduces melanin transfer within the skin. This helps improve uneven tone and reduce the appearance of dark spots over time.
• 
  Oil Regulation and Pore Appearance.
  
• Rather than stripping oil, niacinamide helps regulate sebum activity. This can lead to visibly refined pores and improved clarity.
  It does not shrink pores physically. it improves the biological factors that make them appear enlarged.
  

Clinical research shows:

However, higher percentages are not automatically better.

High free-form niacinamide concentrations can cause tingling or flushing in some individuals.

This is where formulation becomes critical.

Encapsulated Niacinamide: Why Delivery Matters

Encapsulation surrounds niacinamide in a protective carrier that controls release into the skin.

Benefits of encapsulated niacinamide:

In the Rejuvaus Bright & Correct Niacinamide Serum, 10% encapsulated niacinamide is used within a broader multi-pathway system.

Rather than relying on niacinamide alone, the formula combines:

This multi-pathway design supports pigmentation regulation, barrier function and hydration simultaneously.
The result is improved tone without aggressive correction.

Yes. Niacinamide works well with:

In fact, niacinamide often improves tolerance to stronger actives.

Rejuvaus serums are designed to be blended rather than layered, allowing niacinamide to support barrier strength while other ingredients perform their roles.

Myth: Higher percentages work faster

Reality: Delivery system and barrier support matter more than raw percentage.

Myth: Niacinamide causes flushing

Flushing is typically linked to niacin, not properly formulated niacinamide.

Myth: Niacinamide is only for oily skin

Niacinamide benefits dry, mature and sensitive skin due to its barrier strengthening properties.

How Long Does Niacinamide Take to Work?

Long-term barrier improvements continue with consistent use.

Niacinamide performs best when paired with daily UV protection.
