Now they dont mention the uneveness, I guess thats just a result not a side effect
…. You may also feel intense cold, tingling, stinging, aching, and cramping…
Immediately after treatment, there may be redness and firmness; transient blanching (make white or pale by extracting color; bleach.. ) and/or mild bruising around the edges of the treatment area; tingling and stinging. Typically, these side effects are temporary and resolve completely. Many patients do experience redness in the treated areas for up to a few hours after the applicator is removed. In rare cases, this redness may persist up to 2 weeks, but it will completely resolve itself.
At 1 to 2 weeks after treatment, there may be redness, bruising, and swelling; tenderness, cramping, and aching; itching, skin sensitivity, tingling, and numbness. In some cases, numbness may persist for several weeks after a treatment. Talk to your doctor if these side effects persist past 2 weeks or worsen over time.
Rare side effects include:
- Paradoxical hyperplasia:
Visibly enlarged tissue volume within the treatment area, which may develop 2 to 5 months after treatment. Surgical intervention may be required.Definition of hyperplasia: the enlargement of an organ or tissue caused by an increase in the reproduction rate of its cells, often as an initial stage in the development of cancer.
- Late-onset pain with a typical onset several days after a treatment and resolution within several weeks.
- Freeze burn: First- and second-degree freeze burn may occur during treatment. It typically resolves without sequelae with proper care.
- Vasovagal symptoms: Dizziness, lightheadedness, nausea, flushing, sweating, or fainting during or immediately after the treatment.
- Subcutaneous induration: Generalized hardness and/or discrete nodules within the treatment area, which may develop after the treatment and may present with pain and/or discomfort.
- Hyperpigmentation: Hyperpigmentation may occur after treatment. Typically, it resolves spontaneously.
- Hernia: Treatment may cause new hernia formation or exacerbate pre existing hernia, which may require surgical repair.
