　　A

　　The older we get, the more our bodies change, especially our skin. One of the biggest changes: it itches (发痒) more than ever.

　　"Itching is a common problem as we age，" says Dr. Vishakha Gigler. "The skin changes, often becoming thinner, drier and more sensitive."

　　Biological changes are one thing, but there is now strong evidence to support the thinkng that something else is partly to blame: prescription and non­prescription medications. Dr. Gigler says, "I often see seniors in my practice who are suffering from itchy skin. Medical conditions and certain medications can be an underlying (潜在的) cause."

　　Medications commonly prescribed to senior citizens, including pain relievers, blood pressure medications, sleep aids, can often cause increases in skin sensitivity and itching.

　　Many seniors seek relief from itching with products containing steroids (类固醇), but this can present another problem. According to medical professionals, steroidal creams carry their own side effects, including thinned skin, allergic reactions and more itching.

　　Fortunately, one of the best­selling, most effective itch relievers is steroid­free and safe for the whole family to use: TriCalm(r) hydrogel (水凝胶). TriCalm is a non­prescription medication that is guaranteed to relieve itch.

　　TriCalm's strong guarantee and effectiveness are why skin doctors throughout the country are recommending TriCalm to their patients year round.

　　While other products can take up to 24 hours and require repeated applications to get the full benefit, TriCalm works almost immediately, providing rapid relief from itch with a single application, and because TriCalm is steroid­free, it is safe for the whole family to use.

　　TriCalm is also backed by a 100% Money­Back "Itch Free Guarantee，" which promises the product will relieve your itchy skin, or you can send back the empty tube for a full refund.

　　TriCalm is available for purchase at several major retailers (零售店)，including Walmart, Walgreens and CVS/pharmacy. For more information about TriCalm, visit www. TriCalm. com.
