Immediately after treatment:

  • Immediately after subcision, most patients experience:

    • Swelling of the skin
    • Bruising
    • Pain
    • Skin redness
  • Bruising will disappear within a week after the procedure. Most of the other symptoms disappear within two weeks after the procedure.

Days and weeks after treatment:

  • In rare cases, a hematoma (a swollen and bruised area under the skin) may persist for up to 4 months after subcision.

Longer term:

  • Some people may need multiple subcision sessions to obtain the desired results.3
  • In rare cases, patients may experience long-term side effects, such as:

    • Excessive formation of skin (hypertrophia)
    • Formation of fibrous tissue leading to a bump under the skin (subcutaneous nodule)
    • Cysts from disruption of skin oil gland and nearby structures
    • Additional scar or worsening of the scar2

Additional scars and/or worsening of scars 2.5 months after subcision (source: posted on message board) note that they did not post a “before picture” so it is hard to say.
