This is Jumiso's 10% niacinamide serum, positioned to compete with The Ordinary Niacinamide 10% + Zinc 1% but with a Korean formulation sensibility (better textures, fewer irritants, more supportive hydration). 10% niacinamide is the concentration at which most clinical studies demonstrate measurable effects on tone, pore appearance, and sebum regulation. Going higher than 10% rarely provides additional benefit and can cause flushing. At $18 for 40ml, this is competitively priced, about on par with The Ordinary but with a formulation upgrade.
The difference between a cheap 10% niacinamide serum and a well-made one is the supporting formulation. Jumiso includes hydration humectants, barrier-supporting ingredients, and doesn't use a harsh alcohol carrier. For users who found The Ordinary's 10% niacinamide drying or irritating, this is often the next step.
Niacinamide (vitamin B3) is one of the most extensively studied skincare actives. At 10%, it reduces pore appearance, regulates sebum production, supports barrier ceramide synthesis, blocks melanin transfer (brightening), and provides anti-inflammatory effects. Over 8 to 12 weeks of consistent use, expect visibly smaller pores, more balanced oil production, and more even tone.
Apply after toner, before heavier serums or moisturizer. Dispense 3 to 4 drops, press into clean skin. Use AM and PM. Start with PM-only for 1 to 2 weeks to establish tolerance, then add AM if no irritation occurs. Pair with SPF in the morning.
For users stacking actives: apply vitamin C first (AM), this niacinamide second. Old guidance that C and niacinamide shouldn't mix has been debunked in modern formulations; layering is fine with proper products.
For most skin types, 10% is well-tolerated. A subset of users experiences flushing or slight redness; these users typically do better with 5% niacinamide. If you get warmth or redness on first application, dial back to every-other-day use and build up gradually.
Yes. The outdated myth that they shouldn't mix was based on early 20th-century chemistry experiments at high temperatures. Modern formulations layer fine. Use vitamin C first (it needs low pH), then niacinamide after absorption.
Similar active concentration. Jumiso has a lighter, less-tacky texture and Korean formulation support ingredients. The Ordinary is cheaper and more widely available. For basic 10% niacinamide on a budget: The Ordinary. For upgraded texture and supportive formulation: Jumiso.
Reduced midday shine: 2 weeks. Smaller visible pores: 4 to 6 weeks. Fading dark marks and more even tone: 8 to 12 weeks.
Most sensitive skin tolerates niacinamide well; it's typically one of the friendlier actives. Users with rosacea sometimes flush; test on jawline for 3 to 5 days before committing.
Pair with Jumiso Antioxidant Glow Facial Essence for layered brightening, or Torriden SOLID IN Ceramide Cream as the sealing moisturizer with barrier support.
