My upper arms, which had been a complex of mine since I was very young, now fall in a straight line that anyone can see. I honestly wondered if it was even possible, and I'm so happy that it worked that I'm already wearing short-sleeved shirts all the time. As for scars, ha~~~~~ I can't see them either. They're partly hidden in the armpit crease, and I'm too busy looking at my arm line to even notice the scars They told me I bruise more than most people, but unlike the reviews I'd seen on other channels I didn't get a single blue or purple bruise. Just some greenish and yellowish bruising, and even that faded quickly. As for recovery, right when you think you're dying it improves in a sudden jump. The first 3 days are a bit rough, day 4 gets much better, days 7-9 are hard again, and then day 10 gets much better again. I think I was already wearing short sleeves from around the two-week mark haha
