Supposed to promote a more youthful appearance [SEP] This Rose Quartz Roller with Derma Roller 0.25mm is a great value for this facial kit. It’s giftable and is believed that the microneedling treatment and pink jade roller is supposed to stimulate collagen. I’ve only used both for a few days so I can’t say effective this product will be, but I’m willing to give it a try. The jade roller is great to use when applying your favorite face serum. It glides and rolls smoothly. The microneedling treatment is not too painful when you simply apply a little bit of pressure. It did not cause bleeding because I used it gently as directed. You do need to be sure to only use it on clean skin and wash it after each use. I am hoping to see more vibrant skin after using these tools for a few weeks.
