KEY INGREDIENTS
Yes, you can safely use vitamin C and niacinamide together. Our ROI's serum duo is specifically formulated with optimal pH levels to ensure both ingredients work effectively without causing irritation or ingredient conflicts.
Use the Vitamin C serum in the morning after cleansing and before moisturizer. Apply the Niacinamide serum in your evening routine after cleansing. Start every other day and gradually increase to daily use as your skin adjusts.
This serum duo targets multiple concerns: brightens complexion, minimizes pores, reduces oil production, fades dark spots, improves skin texture, strengthens skin barrier, and provides anti-aging benefits for smoother, more radiant skin.
Most users notice improved skin texture and brightness within 2-4 weeks of consistent use. For significant improvements in pore appearance and dark spots, allow 6-8 weeks of regular application.
