Yes, CO2 laser treatment involves a significant level of pain and discomfort. Because this procedure works by removing layers of skin tissue, medical professionals typically administer anesthesia—ranging from topical creams to general sedation—to manage the sensation during the treatment. However, you should expect the recovery period to involve ongoing soreness and sensitivity.
The Bottom Line: While anesthesia manages pain during the procedure, the aftermath feels comparable to a severe sunburn with raw skin. Expect acute post-treatment pain to last for one to two weeks, while full skin healing can take up to six weeks.
Managing Pain During the Procedure
The level of pain intervention depends heavily on the depth of the laser treatment and the size of the area being treated.
Extensive Treatments
For deep resurfacing or full-face treatments, doctors typically use general or dissociative anesthesia.
In these cases, you are sedated to ensure you do not feel the intense heat and abrasion of the laser.
Small or Targeted Areas
If you are treating a smaller, specific section of skin, the doctor may opt for local anesthetic injections.
This numbs the immediate area, blocking pain signals while allowing you to remain awake.
Surface-Level Discomfort
For less invasive sessions or minor corrections, a topical anesthetic cream is often applied beforehand.
This dulls the sensation of the skin but may not block the feeling of heat entirely.
The Recovery Phase: What to Expect
The pain does not end when the laser is turned off. The healing process involves a specific recovery timeline regarding physical sensation.
Immediate Aftermath
Immediately following the procedure, the skin will feel very raw.
Patients often describe the sensation as a severe sunburn. You may experience drainage (oozing) from the treated areas.
Duration of Pain
Acute post-treatment pain generally persists for 1 to 2 weeks.
During this time, the skin is fragile and highly sensitive to touch and environmental factors.
Pain Management at Home
To handle discomfort during recovery, doctors often recommend over-the-counter pain medication.
Applying ice packs can also help reduce the burning sensation and swelling.
Understanding the Trade-offs and Risks
CO2 laser treatment is aggressive, and with that intensity comes specific risks and physical side effects beyond simple pain.
Extended Healing Time
While the acute pain may subside in two weeks, the skin takes up to 6 weeks to fully heal.
Furthermore, residual inflammation and redness can persist for up to 6 months after the procedure.
Skin Reactions and Texture
You may experience peeling, redness, and changes in skin tone, such as hypopigmentation (lightening) or hyperpigmentation (darkening).
Some patients develop milia, which are small white or yellow cysts, during the healing process.
Infection and Viral Risks
Because the skin barrier is compromised, there is a risk of infection and scarring.
Notably, the laser can reactivate the herpes simplex virus. Prophylactic medication is sometimes prescribed to prevent this complication.
Planning Your Recovery Strategy
Success with CO2 laser treatment requires preparing for the downtime as much as the procedure itself.
- If you are treating a large surface area: Prepare for general or dissociative anesthesia and arrange for someone to assist you immediately after the procedure.
- If you cannot commit to a long recovery: Be aware that you may need to stay home and avoid strenuous activity for several weeks while the raw skin heals.
- If you are prone to cold sores: inform your doctor immediately so they can prescribe preventative medication to avoid viral reactivation.
Recovery is a slow process, but strict adherence to aftercare—including sun avoidance and wound care—is essential for minimizing pain and achieving the desired results.
