Face serum is a lightweight, highly concentrated formulation that penetrates below the skin’s surface to deliver active ingredients like glycolic acid and hyaluronic acid to the skin. With this targeted approach to skin concerns, serums can often improve your skin’s overall appearance more quickly than a cream or moisturizer. Take, for example, Bye Bye Breakout Salicylic Acid Acne Serum: It’s clinically tested to visibly reduce acne in just 3 days* and fade the look of post-acne marks in 8 weeks.** Learn more about how serums work here.
