When it comes to customizing our skin care routines to target concerns like fine lines, dark spots, and a dull complexion, we always turn to a certain magic potion that can tackle an array of skin ailments—and by magic potion, we mean facial serum. For those unfamiliar: Serums are formulas that are often highly concentrated and consist of nutrients, vitamins, and a boat-load of other beneficial ingredients. They are applied after an alcohol-free toner and before a moisturizer and can be used all over the face or as a spot treatment. Using a serum that can target specific skin concerns in your daily skin care regimen can not only reduce their appearance, but can help improve the overall appearance of your complexion, too. Our top three must-try serums by skin concern, below.Kiss Dull Skin Goodbye  Inspired by the skin’s natural renewal process, Vichy’s Idéalia Life Serum contains the brand’s first behavioral molecule association, LR2412 + LHA, which can boost the skin’s resistance to external aggressors, micro-exfoliate, and stimulate the skin’s renewal process. Micro-exfoliating the skin can help target pigmentation, which may result in a complexion that is brighter and more youthful-looking. This lightweight formula can also work to hydrate the skin and contains golden and pink micro-pearls that may illuminate the complexion for youthful-looking skin.  Vichy Idéalia Life Serum, $39Say No To Dark SpotsLooking for a serum that can help reduce the appearance of dark spots? Look no further than Kiehl’s Clearly Corrective Dark Spot Solution. This silicone-free, paraben-free, and fragrance-free, fast-acting serum—formulated with vitamin C, peony extract, and birch extract—can brighten the look of dark spots and help your skin to appear more youthful.   Kiehl's Clearly Corrective Dark Spot Solution, $49.50What Wrinkles?The great thing about serums, is that they can be used to treat certain problem areas, like crow’s feet and other types of wrinkles that form around the eye. Luckily, Giorgio Armani Beauty’s Crema Nera Extrema Serum can address those fine lines, and then some. This “Youth Memory Eye Serum” can visibly lift and restore the youthful shape of the eyes and leave the skin feeling more nourished.   Giorgio Armani Crema Nera Extrema Eye Serum, $150
