According to New Jersey plastic surgeon Dr. Sam Rizk, M.D., in an interview in this week’s Star, there are several differences between ablative and non-ablative lasers:

Ablative Lasers

• Also called: Erbium, CO₂
• Treatments needed: 1
• Used for: Wrinkle reduction, tissue tightening
• Relative downtime: Significant. Up to 10 days post-treatment.

Non-Ablative Lasers

• Also called: Fraxel, Affirm
• Treatments needed: Several. Number varies; usually at least 3.
• Used for: Sun damage, skin texture and discoloration treatment.
• Relative downtime: Not significant.

One note of caution

According to renowned dermatologist Dr. Jeannette Graf, M.D., in the April 2008 issue of Allure magazine, “Lasers [are the most overhyped anti-aging treatment] – particularly the new radio frequency machines such as Fraxel and Thermage. There’s a small percentage of people who do well with them, but there’s a huge percentage for whom they do nothing.” Thankfully, lasers are (for now) only administered by licensed professionals, so speak to your dermatologist or plastic surgeon to see if you a good candidate for any laser procedure.
