Immediately after treatment:
- Immediately after subcision, most patients experience:
- Swelling of the skin
- 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.
- 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 Acne.org message board) note that they did not post a “before picture” so it is hard to say.
