Niacinamide 10% & Zinc 1% Oil Control Serum – 60ml

This serum combines a high-strength concentration of niacinamide (a form of vitamin B3) with 1% zinc to help regulate excess oil production and promote clarity. It is designed to reduce pore visibility and improve skin texture, leaving skin looking smoother and more radiant. In a clinical study of 35 subjects applying the product twice daily for 8 weeks, visible improvements in skin smoothness and hydration were seen within 7 days, and reduced excess oil was noted in 3 days (per boots.com).
