Hello everyone. I just bought a Derma roller / micro needler along with some Hyaluronic acid serum. Not quite sure how to use, does anyone else use a dermaroller and have you noticed a difference? I think I’m going to put the serum on, use the roller, then finish with more serum. Really excited to see how it turns out as my skin is currently terrible, despite a very healthy diet and three litres of water a day!
