Sofwave Side Effects
Reviewed by Dr. Alexander Landfield, Board-Certified Neurologist
Sofwave is an FDA-cleared non-invasive skin tightening device that uses Synchronous Ultrasound Parallel Beam (SUPERB) technology to stimulate collagen production in the mid-dermis. Side effects are minimal compared to surgical alternatives. Rani Beauty Clinic offers Sofwave treatments under physician supervision for patients seeking non-surgical lifting and tightening of the face, neck, and body.
Common Side Effects
Redness and mild flushing
mildDuration: 30 minutes to 4 hours
Management: No treatment is typically necessary. Redness fades quickly and most patients can resume normal activities, including applying makeup, immediately after the session.
Mild tenderness in treated areas
mildDuration: 1–3 days
Management: Acetaminophen (Tylenol) can be taken if needed. Avoid firm pressure or massage on treated areas for 24 hours. Tenderness resolves on its own.
Temporary swelling
mildDuration: 1–3 days
Management: Apply a cold compress if desired. Swelling is typically subtle and resolves quickly. It may be more noticeable along the jawline and under the chin.
Warmth in the skin during and after treatment
mildDuration: 1–2 hours
Management: The warming sensation is from the ultrasound energy reaching the mid-dermis and is a normal part of the treatment process. It subsides shortly after the session ends.
Rare Side Effects
These are uncommon but patients should be aware of them.
- Temporary numbness or tingling in the treated area
- Mild bruising (uncommon)
- Temporary welts or raised areas along treatment lines — typically resolve within hours
- Nerve irritation — rare and temporary, resolving within days to weeks
When to Contact Your Provider

How to Minimize Side Effects
- 1Arrive to your appointment with clean, product-free skin on the treatment area
- 2Disclose any active skin conditions, infections, or implants in the treatment area

- 5Maintain realistic expectations — collagen remodeling results develop over 2–3 months
Frequently Asked Questions
How painful is Sofwave treatment?
Sofwave is designed with integrated cooling (Sofcool technology) that protects the skin surface and reduces discomfort. Most patients describe the sensation as a warm, pulsing feeling. Discomfort varies by treatment area, with bony areas (forehead, jawline) being more sensitive. No topical numbing is required for most patients, though it can be applied upon request. The procedure typically takes 30–45 minutes.
Is there downtime after Sofwave?
Sofwave has minimal to no downtime. Most patients experience only mild redness lasting 30 minutes to a few hours. There is no peeling, bruising, or extended recovery period. Patients can return to work, apply makeup, and resume normal activities immediately after treatment. This makes Sofwave a popular option for patients who want skin tightening without the downtime of surgical procedures.
How soon do you see results from Sofwave?
Some patients notice an initial tightening effect within the first few weeks, but the primary results develop gradually over 2–3 months as new collagen and elastin are produced in the treated tissue. Results continue to improve for up to 6 months. A single treatment session is typically sufficient, with results lasting 1–2 years depending on the individual's aging process and skin condition.
Can Sofwave cause nerve damage?
Sofwave technology targets a specific depth in the mid-dermis (1.5mm) using parallel ultrasound beams, which is above the depth where major facial nerves are located. Temporary tingling or numbness has been reported in rare cases and resolves on its own within days to weeks. Permanent nerve damage from Sofwave has not been documented in clinical studies.
Is Sofwave safe for all skin types?
Sofwave is FDA-cleared for all skin types (Fitzpatrick I–VI). Because the ultrasound energy bypasses the epidermis and targets the deeper dermis, it does not interact with melanin, making it a safe option for darker skin tones without the risk of hyperpigmentation associated with some laser treatments. This is one of Sofwave's key advantages over light-based skin tightening technologies.
