This small-but-mighty serum was created by derms and promises to improve your skin within three weeks of treatment. The natural approach to ingredients -- bee venom, honey and royal jelly, to name a few -- uses organic enzymes alongside hyaluronic acid and glucosamine to reduce inflammation and improve scarring. In the serum world, this price point isn't too shabby, either.

A few drops goes a long way with this pimple- and wrinkle-busting serum. A brand known for its gentle approach to skin care, Clinique pairs hydration with allergy-tested and 100 percent fragrance-free ingredients in their blemish-control line. The salicylic acid will tackle those breakouts while many extracts, oils and even caffeine will leave skin looking fresh and plump.

So while technically not a serum, this new acne-fighting lotion is getting rave reviews and quickly attracting a mass following. The Nerd Skincare acne line includes everything from a cleanser to a cream, and this light, serum-like lotion is queen for helping you battle breakouts. It has all of the good stuff that serums have: glycerin, protein and plenty of natural ingredients, but none of the tough stuff that sets sensitive skin aflame. Instead of salicylic acid and benzoyl peroxide, Nerd uses sulfur to clear breakouts and cultivate a strong skin barrier.
