I have pretty decent skin at 48, definitely getting some smile wrinkles around my eyes, some forehead wrinkles, but overall, look on the younger side of my age. I just started getting these weird under eye criss cross wrinkles and and decided to look into a product or treatment for that sensitive area. I bought this derma roller about 3 or 4 weeks ago, and have used maybe 5 times. I sterilized it and my face with 70 percent iso alcohol, rolled over my whole face and neck, then rinsed and sterilized microneedler and face again. The under eye area looked amazing, criss cross wrinkles were just plain gone. I thought it was probably due to swelling and they would be back in a day or two... still gone! What I noticed even more was the texture of my skin...super glowy and clear...like no foundation or makeup clear. Even better, when I did apply foundation, it went on flawlessly. For the price, this is the most effective item I have EVER used and as most of us, I have spent plenty on gadgets, potions and treatments over the years. My use has been the following: weekly use (maybe twice a week on occasion or on a particular area), sterilization of both skin and roller before and after treatment with 70% isopropyl alcohol, then application of the dermacell collagen cream, or dermac+ anti-aging serum. I usually do not use any make up or harsh products for 24 hours after figuring my skin would be more prone to breaking out. They equate it to exfoliation, but I have exfoliated plenty in my lifetime and with plenty of different products...never had results this good.
