I love this product sooo much! I honestly don't know how I lived without it for so long. Being in lockdown without beauty salons being available, I thought I would invest in some at home equipment to keep my skin looking good and I have to say I have not been disappointed with any of it! I chose the 0.5mm derma roller and also it's a slight discomfort, I love it! Your skin looks glowy and dewy immediately after and a little bit red but I do mine at night so by the morning this has gone. I apply a stem cell serum before and after for a more comfortable application and product absorption. It only takes 5 minutes and after a couple of times you get used to how much pressure to apply etc. I watched an official video on YouTube before using to get a better idea of how and when to use it which was really helpful. Overall 5/5 for service, effectiency and availability from Current Body. Thank you!
