Turn Back the Clock, From Head to Toe

De-wrinkle knees and elbows
At home: Soothe dry skin with moisturizer containing ammonium lactate or urea—both help moisture get through the skin barrier. Two to try: AmLactin Moisturizing Lotion ($12) and Eucerin Plus Intensive Repair Body Cream ($8.49). Take the focus off wrinkly knees by giving your legs an allover glow. Deyette suggests Jergens Natural Glow Express Body Moisturizer ($8.99). And exfoliate elbows with your favorite cream or brush.

At the doc’s: You could consider a knee lift like Demi Moore famously had done. But here’s a better idea: Sign up for a yoga class. Poses that strengthen the quadriceps (e.g., Chair, Warrior I, and Warrior II) support and strengthen the knee joints, and also tighten the surrounding skin and muscle. If dry, droopy elbows bug you, ask about skin-tightening injections.

TLC for beat-up feet
At home: Moisturize cracked heels at bedtime. Shop for comfortable shoe brands like Aerosoles, Söfft, or Cole Haan, which builds Nike Air cushioning into dress shoes and boots.

At the doc’s: Cortisone injections or surgery are options for painful bunions.
