Your skin is one of your most important physical assets. While diet and genetics play a role in determining the health and appearance of your skin, over-the-counter skin creams may be effective at improving your appearance or healing and preventing skin damage. Depending on what you use over-the-counter skin creams for, you may need to try several different brands before finding the one that works best for you.
Inhibitor Creams
Inhibitor creams protect your skin from damage. The most well-known inhibitor cream, also available in gels and sprays, is sunscreen. Sunscreen works by absorbing sunlight and deflecting dangerous ultraviolet rays away from the skin, allowing you to enjoy your time outdoors without worrying about sunburn. You must reapply most sunscreens periodically for maximum protection. Another less well-known variety of inhibitor cream available over the counter protects surfers and beachgoers against jellyfish stings. Dr. Alexa Kimball, an assistant professor of dermatology at Stanford University, claims the inhibitor cream works by repelling water and confusing the communication sensors in the jellyfish's tentacles---allowing it to sting yet not release venom.
Wrinkle Creams
A wide variety of wrinkle creams are available over the counter for aging consumers. A 2010 "New York Times" report suggests that, although additional studies are necessary, some wrinkle creams may be effective at treating and preventing fine lines by providing the skin with the antioxidants it needs to stay healthy. Look for over-the-counter wrinkle creams that contain antioxidants such as coenzyme Q10, selenium and alpha-lipoid acid. Although retinol is a common ingredient in wrinkle creams, keep in mind that over-the-counter retinol is not regulated by the U.S. Food and Drug Administration.
Moisturizers
If your skin cracks, itches or appears scaly, you may suffer from dry skin. According to MedlinePlus, dry skin is most common on the lower legs, arms and thighs and can occur frequently during the colder months. Over-the-counter moisturizers can help you treat dry skin and prevent future occurrences. Look for a moisturizing cream with a high oil content, as thick, greasy creams work best to restore your skin's natural oils and prevent dryness.
Medicated Creams
Medicated creams are available over the counter to treat bug bites, minor cuts and scrapes, sore muscles, and acne. When using over-the-counter medicated creams, take care to use them in moderation. A 2008 CNN report notes that, in large doses, medicated creams can cause illness and, in some cases, death. Conduct an allergy test by applying the medicated cream on a small area of skin first, and never use more than the recommended amount. If you have concerns about using medicated skin creams to treat minor ailments, ask your physician for a recommendation.
