By preserving the skin's natural oil balance, THALIA 5% NIACINAMIDE PORE TIGHTENING SERUM 30ML helps minimize pore size and smooth out uneven skin texture. The pores appear more stretched and larger the more dead tissue and oil they contain. The pores expand less the less oil that is trapped within them. Smaller pores on your skin can give it a smoother appearance. Vitamin B5 helps you achieve tighter skin by providing your skin with intense hydration. HOW TO USE: Apply just a few drops to your cleansed face and neck in the morning and evening. Following that, you can moisturize your skin with Thalia moisturizing cream.
