Vacuum Suction Technology for Safe RF Microneedling Treatments With the application of vacuum suction technology, you can penetrate Radiofrequency energy deep into the dermis to cause a thermal effect. The thermal effect causes an instant contraction to the fibrous septa and dermis which boosts collagen and elastin production, with continuous results seen over the following 3 – 6 months. This fine penetration depth control function through vacuum-based absorption can be customised to fit a variety of skin conditions.Vacuum suction technology allows you to pull up the treatment area to stabilise the microneedles for safer and more precise treatments – especially useful around the delicate eye area.
