Daily visible oil and pore control serum. A fast-acting multi-functional serum to reduce the looks of pores (number and surface), shine, congestion and dermal impurity. Note: Pore Control is not designed to dry out the skin. Oily, congested skin types can actually be dehydrated as hydration refers to the water content of the skin and not the oil content. Similarly, dry skin can look congested with prominent pores. Pore Control helps increase the skin's ability to retain water while regulating the looks of pores and sebum activity.
