⚠️ Do Not Mix With...
- •High Percentage Vitamin C (Pure L-Ascorbic Acid): While safe for most, using pure, high-percentage L-Ascorbic Acid and Niacinamide together can cause temporary flushing (redness and warmth) in sensitive skin. Apply them in different routines or wait 15 minutes between applications.
- •AHAs / BHAs (e.g., Glycolic or Salicylic Acid): Not a strict conflict, but layering multiple actives with Niacinamide can overwhelm a compromised barrier. Alternate use nights if sensitive.
What is Niacinamide?
Niacinamide is a form of Vitamin B3. Unlike some trend-driven ingredients, Niacinamide has decades of solid scientific research backing its efficacy. It's incredibly stable in formulations and plays nicely with almost every other active ingredient, making it a staple in countless K-Beauty products.
What does it do?
It might be faster to list what Niacinamide doesn't do. It is a true all-rounder:
- Brightens and Evens Tone: It inhibits the transfer of melanin (pigment) to the skin's surface, effectively preventing and fading dark spots, sun damage, and post-acne marks.
- Regulates Oil: It helps normalize sebum production, making it a game-changer for oily and combination skin.
- Minimizes Pores: By keeping oil production in check and improving skin elasticity, it makes pores appear visibly smaller.
- Strengthens the Barrier: It boosts the skin's natural production of ceramides, reinforcing the protective barrier and preventing moisture loss.
Who is it for?
Niacinamide is suitable for virtually everyone, but it shines brightest for:
- Oily and Acne-Prone Skin: It controls the oil that leads to breakouts.
- Those with Hyperpigmentation: It safely and gently brightens dark spots without the irritation of stronger acids.
- Aging Skin: Its barrier-strengthening and collagen-boosting properties help soften fine lines.
Note: While highly tolerable, some people may experience flushing or irritation at very high percentages (over 10%). Stick to 2-5% for daily use without irritation.
