Is CO2 laser permanent?

Resurfacing changes the surface and triggers new collagen remodelling during healing. Once the skin has recovered, smoother texture or softer scar contours may remain for a long time, but the result is not a promise that the original concern will never reappear.

Sun exposure can contribute to new pigment and texture changes. Natural ageing, hormonal changes, acne activity, weight change and movement around a scar can also alter the appearance. Some people need a staged plan or later maintenance, while others may decide that one treatment is enough for their goal.

Ask for a plan that matches your concern rather than choosing treatment because it is described as permanent. Discuss whether fractional or deeper resurfacing is appropriate, what changes are realistic, and whether another session might be considered only after the skin has fully settled.

Use the sun protection recommended by your clinician, avoid picking during recovery, and treat new inflammation promptly. Keep photographs or notes for your own comparison after healing; judging the result while redness or swelling is present can be misleading.

Contact the clinic if the treated area develops worsening pain, spreading redness, drainage, fever, new thickening or a delayed wound. A sudden change in colour, texture or sensation should be assessed rather than assumed to be a normal part of lasting results.

Ask what improvement the treatment is targeting, how long assessment should be delayed while healing settles, what may cause the change to fade, whether maintenance is relevant, and how you should protect the area from sun and irritation.
