At Naples Longevity Clinic, our aim is to have you Feel Younger....Look Younger and actualIy…Become Younger! Theories of aging revolve around four basic principles; Glycation (Sugar Metabolism), Inflammation, Oxidation (Free Radicals), Methylation (Abnormal gene expression). Physicians used to believe that our hormone levels decline because we age, but modern research has shown that we age in part because our hormone levels decline.
