Microneedling rollers are durable, high-quality precision tools and are produced in quality-controlled, certified manufacturing facilities. They deliver ingredients by mechanically perforating the outer skin layer and allowing for transdermal absorption of solutions. The microneedling rollers are sterilised within the UK with the correct dose of sterilisation to eradicate bacteria. Each roller comes with a lot number and an expiry code that you must put on your clients consultation form.
