What is Pore & Acne Scar Treatment?

Large pores and acne scars relate to damaged dermal collagen. Microneedling radiofrequency (Potenza) delivers heat and micro-injury to the dermis, and fractional CO2 laser (U-Pulse CO2) creates micro-columns that trigger regeneration.

Common concerns

  • Enlarged pores
  • Depressed acne scars
  • Uneven texture
  • Stretch marks and scars

Treatment areas: cheeks, forehead, around the nose, scarred areas.

Key facts

  • Device / product: Potenza and U-Pulse CO2
  • Treatment time: about 30–60 minutes (plus numbing time)
  • Anaesthesia: numbing cream
  • Downtime: redness for 2–3 days after Potenza; small scabs for about 5–7 days after fractional CO2
  • When results show: gradual improvement over a series of sessions
  • Repeat interval: usually several sessions 4–6 weeks apart
