The Niacinamide Serum 12% Plus Zinc 2% is a powerful formula that combines the benefits of niacinamide and zinc to address various skin concerns. Niacinamide helps to regulate oil production, minimize the appearance of pores, and improve uneven skin tone. Zinc works to control sebum production and reduce inflammation. However, some individuals may experience skin sensitivity or irritation when using this serum. It is recommended to perform a patch test before incorporating it into your skincare routine.
