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.

* Visible improvement began at Day 3 and improved throughout 8-week clinical study.
**Based on an 8-week clinical study.

Finding the best face serum for your skin concerns starts with knowing what active ingredients to look for. Dull skin? Find a serum containing vitamin C. Dark spots? Look for niacinamide. Are pimples the problem? Look for acne treatments that contain a blend of salicylic acid, lactic acid and postbiotic ferment to help target active acne breakouts, gently exfoliate, and calm and balance the look of skin. For large pores, glycolic acid is your go-to and for lines and wrinkles, hyaluronic acid is your hero ingredient.

Face serum should be applied before your moisturizer. Because serums are lightweight in texture, it is best they are applied directly to clean dry skin for maximum efficacy and then sealed in with your favorite moisturizer. Learn more about how to layer your skincare products.
