Microdermabrasion treatments that buff aging, sun-damaged skin bring about molecular changes that help rejuvenate and improve an older adult's appearance, according to a new study.

The procedure - which is performed with a fine sandblaster-like device that sprays tiny grains of diamond or another hard substance across the face - takes off the dead, outer layers of skin to improve the appearance of wrinkles,  acne scars, dyspigmentation and other signs of aging skin, according to a report in the October issue of Archives of Dermatology. 

To change the appearance of wrinkled skin, microdermabrasion induces the production of collagen, the major structural protein in the skin. More than one treatment is usually needed to kick things up a notch and reduce or remove fine wrinkles among aging boomers seeking a youthful appearance. 

"The beneficial molecular responses, with minimal downtime, suggest that aggressive microdermabrasion may be a useful procedure to stimulate remodeling and to improve the appearance of aged human skin, researchers said in the report.

'An effective procedure'
Dr. Darius Karimipour and colleagues at the University of Michigan, Ann Arbor, conducted a biochemical analysis of skin biopsy specimens before and four hours to 14 days after a microdermabrasion procedure on the sun-damaged skin of 40 volunteers' arms. The volunteers were aged 50 to 83.

When performed with a coarse-grit hand piece, microdermabrasion resulted in the increased production of a wide variety of compounds associated with wound healing and skin remodeling. However, these changes were not seen in individuals who received treatments using a medium-grit hand piece, researchers wrote. All patients experienced a mild period of redness that typically lasted less than two hours.

"We demonstrate that aggressive nonablative microdermabrasion is an effective procedure to stimulate collagen production in human skin in vivo," according to the report.

$139 per session
Treatments, on average, costs about $139 per session, according to American Society for Aesthetic Plastic Surgery data. The number of sessions recommended for maximum results can range between five and to a dozen, spaced two to three weeks apart. Maintenance requires frequent repeat treatments after the initial regimen is completed.

Given the cost, microdermabrasion has suffered a bit with the down economy. The American Society of Plastic Surgeons reported earlier this year that the number of treatments had fallen 6 percent between 2008 and 2007. However, unlike facelifts, there is no downtime with this advanced skin buffing - a big draw to many older adults seeking a less invasive alternative to plastic surgery.

Additionally, other cheaper alternatives such as mineral-based make-up that deflect light and reduce the appearance of wrinkles, can help create a smooth, natural look many boomer women seek.
