I am 48, have been using dermawand for 9 years. It helps with frowned brow, smile lines, jaw line, and I have NO crows feet at 48. It doesn't totally get rid of lines, but reduces them by a large %. People think I'm in late 30's or just starting my 40's. At first, it took a month to see results.
Tips: I use it with a fair amount of pressure for 30-45 minutes every night. If its not every day for a good amt. of time, u won't get good results. It's a pain in the butt, but just use it in front of tv. You don't need the products that come with it. Just use your own favorite moisturizer, ideally do your routine at night, & use your night moisturizer if it works well with the wand. Make sure your skin isn't pulling due to not enough moisturizer, or too thin of one. I only replaced mine once, but I wasn't careful enough with the cord. When u get a new one, just sign up for the warranty. You may also want to check Craigslist or Kijiji in your area, as u can find next to new sometimes. The bottom line is you must use this every day, and I also use the high setting at all times for all areas incl. crows feet area.
