1. Older Population Continues to Grow.Almost a quarter of the US population is above the age of 55, according to 2010 census data (census.gov). A quarter of all American women are 55 or older, as are 22 percent of men. Those aged 55-64 account for 11 percent of the total population, and those aged 65 and up account for 12.5 percent of the population. Among the nearly 38 million Americans over the age of 65 are more than four million citizens age 85 or older.

2. Even “Elderly” Patients Seek Cosmetic Procedures.More than a quarter of cosmetic surgeries and procedures performed in the US are on individuals age 50 to 64, 2010 survey data from the American Society for Aesthetic Plastic Surgery show. Those age 65 and older had seven percent of all procedures performed in the US.

3. Melanoma Prevalence Correlates to Age.The incidence rate for cutaneous melanomas in individuals aged 65 or older in the US is 73.9 per 100,000 individuals, according to SEER statistics. For both sexes and across various ethnic groups, the prevalence of melanoma correlates with age, with an overall prevalence of around 0.5 percent for all Americans over age 70.

4. Rates of STDs Rising.Men who take drugs for erectile dysfunction (ED) have higher rates of STDs, including HIV, than do peers who do not use the drugs, data show (Ann Intern Med. 153(1): 1-7). The STD risk in this population was elevated both in the year before and the year after receiving the prescription for ED therapy. Additionally, data from the CDC suggest that rates of STDs overall are rising more rapidly in seniors than in the population as a whole.

5. Skin Functions Decrease with Age.Among the main functions of the skin that decrease with age are cell replacement, barrier function, chemical clearance, and mechanical protection, according to Robert Norman, DO, author of the 2008 book Diagnosis of Aging Skin Diseases. In the book, Dr. Norman describes various other functions known to decrease, which include immune responsiveness, wound healing, thermoregulation, DNA repair, sweat and sebum production, and vitamin D production.
