HOW IT WORKS

Niacinamide boosts the production of ceramides and fatty acids that strengthen your skin's natural barrier. It also slows pigment transfer to skin cells, helping fade dark spots over time. On top of that, it supports collagen production for firmness and has antioxidant properties that protect against UV, blue light, and pollution damage. 2

KEY BENEFITS

Evens Skin Tone and Fades Dark Spots: Helps reduce the appearance of hyperpigmentation, age spots, and uneven skin tone by slowing the transfer of pigment within the skin. 2
Reduces Fine Lines and Wrinkles: Supports collagen production to help maintain firmness and smoothness, with visible improvements over consistent use. 2
Strengthens the Skin Barrier: Boosts the production of ceramides and fatty acids in the outer skin layer, reducing moisture loss and improving the skin's ability to protect itself. 2
Protects Against Blue Light and Pollution: Helps defend skin cells against damage from everyday environmental stressors including screen-emitted blue light and urban pollutants. 2

INTERACTION WARNINGS

Non-sensitizing and well tolerated at typical cosmetic use levels. May cause skin irritation in susceptible individuals. 4 As a general reminder, avoid combining Cellexia products with retinol products. A patch test is recommended before first use.
