This is the ONLY home microneedle device I will ever buy, especially after reading the reasons why not to use a roller. The gold needles are worth it too, they use gold at my acupuncture clinic to prevent allergic reactions. I get VERY red when I use my Banisher. All irritation and puffiness subsides by morning. I only use it once a week (more is not better!) Yes, it hurts. Yes, it is worth it. Consistenct is key, and gradual change is the goal. Don't waste your money on basic microneedle stamps at .25mm. The Banisher .5mm is the real deal!!
