Punch Techniques

The charts below show the chances of developing various side effects from punch techniques procedures.4 For some side effects, we currently do not have enough data to provide a percentage.

Certain/Likely Side Effects (% = Incidence)

SHORT TERM Itchingup to 25%
SHORT TERM Scabbingup to 20%
SHORT TERM Swelling immediately after procedure (edema)up to 15%
SHORT TERM Wound dischargeup to 10%
SHORT TERM Painup to 5%

Possible/Rare Side Effects

LONG TERM Rest scar tissue (some scar tissue remains from acne scars, or new tissue forms after stitching up)incidence not known
LONG TERM Punch grafting only: Mismatch of skin color and textureincidence not known
LONG TERM Punch grafting only: Graft failure (the skin rejects the graft, and the grafted skin comes off)incidence not known

Studies:   

One study has looked at the side effects of punch elevation:

  • Study 1:

    • Authors: Faghihi et al.4
    • Total # of patients: 21
    • # of female patients: not reported
    • # of male patients: not reported
    • Age of patients: Average: 23.4
    • Duration of treatment and follow-up: 1 session punch elevation, followup at 16 weeks
    • Side effects:

      • Itching: 25%
      • Scabbing: 20%
      • Edema: 15%
      • Wound discharge: 10%
      • Pain: 5%  

Study 1: In a study published in 2015 in the Indian Journal of Dermatology, Faghihi and colleagues randomly assigned 42 patients to one of two groups. The first group received punch elevation followed by fractional CO2 laser treatment, and the second group received only fractional CO2 laser treatment. To determine which side effects were due to punch elevation, the researchers compared the side effects in the two groups.4

The graph below shows a comparison of the side effects on the third day after treatment.4
