Compared to microneedling, nano infusion is less invasive.

• A. Nano infusion is more invasive
• B. Nano infusion is less invasive
• C. Nano infusion uses deeper needles
• D. Nano infusion has longer downtime

Answer: (B)

Invasiveness is about how much tissue disruption a procedure causes. Microneedling punctures the skin with needles to create microchannels, which penetrates deeper and leads to more inflammation and a longer recovery. Nano infusion uses ultra-fine, shallower channels or a non-penetrating delivery method, so it disrupts far less tissue. That means there’s less trauma, milder downtime, and quicker recovery, making nano infusion less invasive than microneedling. The other options would imply deeper penetration or longer downtime, which isn’t how nano infusion works.
