Layering Skincare: What to Mix (and What Not to Mix) with Niacinamide

The Golden Rules of Layering Niacinamide

Niacinamide is famously a team player in the skincare world, making it a staple in popular Korean skincare routines. However, to get the maximum benefits without irritating your skin barrier, it is crucial to know what to mix it with and what combinations to approach with caution.

Best Niacinamide Combinations (The Do’s)

• Niacinamide + Hyaluronic Acid: The ultimate hydration duo. Hyaluronic acid draws moisture into the skin, while niacinamide strengthens the barrier to lock that moisture in. Apply hyaluronic acid first on damp skin, followed by niacinamide.
• Niacinamide + Retinol: Retinol is fantastic for anti-aging and acne, but it can cause peeling and redness. Niacinamide’s soothing, barrier-strengthening properties perfectly counteract retinol’s harsh side effects. Apply niacinamide first to buffer the skin, then apply retinol.
• Niacinamide + Ceramides / Peptides: Mixing these creates an anti-aging and barrier-repairing powerhouse, ideal for mature or sensitive skin.

Combinations to Approach with Caution (The Don’ts)

• Niacinamide + High-Strength Vitamin C (Ascorbic Acid): While modern formulations are more stable, mixing pure Vitamin C with niacinamide can sometimes cause temporary redness or flushing in sensitive skin. Pro tip: Use Vitamin C in your morning routine and Niacinamide at night.
• Niacinamide + Direct Acids (AHA/BHA): Alpha and Beta Hydroxy Acids (like glycolic or salicylic acid) have a low pH, which can sometimes destabilize niacinamide and cause stinging. If you want to use both, apply your acid exfoliant, wait 15-20 minutes, and then apply niacinamide, or simply use them on alternating nights.
