Pearl is a fully ablative laser that is wonderful for early photoaging, especially for dark spots and dull, lifeless complexions. It requires only 1-2 treatments in contast to Fraxel Restore which requires 3-6. The social downtime is 4-7 days depending on the settings used. It gives your skin a fresh start, getting rid of all those years of sunbathing and tanning beds. The duration of effect will depend on how much sun damage you get AFTER the procedure. The regular use of sunscreens daily, along with topical antioxidants like green tea extract or vitamin C, and topical reinol, Renova, or Avage at night will allow your skin to look younger for YEARS! Of course, you will continue to age, so likely you will need to add fillers at some point, and maybe need Fraxel or pearl again in 3-5 years. Good luck and be smart.
