As we age, factors such as genetics, stress, sun exposure, nutrition, sleep and exercise may affect the body’s health and appearance. Eating a healthy diet and exercising regularly are important ways to help maintain overall health throughout life. While these habits may contribute to a healthy appearance, there are various cosmetic treatments and rejuvenating procedures that can reduce some of the changes that occur naturally over time. Some procedures have results that last a few weeks or months, while others may last for a number of years.
