Niacinamide is well-known for its ability to minimize enlarged pores by normalizing the pore lining, preventing oil and debris buildup that can cause blockages and skin texture issues. Regular use helps pores return to their natural size, and higher concentrations can improve sun-damaged skin with “orange peel” texture. Additionally, niacinamide enhances the skin’s moisture retention by boosting the effectiveness of moisturizers, which helps reduce dryness and flaky skin. It also brightens the complexion by preventing and reducing discolorations caused by excess melanin, promoting an even skin tone.
