Superhero serums: Find the right one for your skin

Here's how serums work, in case you missed the memo: The highly concentrated formulas (you might say the triple espressos of skincare) are made up of a combination of active ingredients — vitamins, antioxidants and plant extracts — and are designed to take aim at specific skin conditions (acne, dry skin, wrinkles, dark spots and sagging, to name a few). Unlike moisturizers, which can sit on top of your skin, serums are finer formulas that easily absorb and penetrate deeper into the epidermis. It's easy to sneak one of these powerful elixirs into your routine: Massage a few drops onto your skin after cleansing, let it absorb, then apply your moisturizer, sunscreen or night cream to help lock in the benefits. Remember, a little goes a long way.
