Even with the added moisture in the air, it is still important to continue using a serum in your daily beauty routine during the summer months. A serum can penetrate deeper into the layers of the skin than a regular moisturizer. Kiehl’s Since 1851 Precision Lifting & Pore-Tightening Concentrate ($64) is a great choice. It’s a clinically tested serum that restores elasticity for more toned, uplifted looking skin. Pore size appears reduced and lines and wrinkles look diminished. The serum can be used both morning and night and should be applied to cleansed skin. For added hydration, follow with a moisturizer. Look for this nourishing product at the Kiehl’s store located on Level One near Nordstrom.
