What Should I Know About Hypopigmentation Before a CO2 Laser Correction for Acne Scarring?

My dermatologist/surgeon wants to use CO2 laser for acne scarring. The scarring is not too extensive or extremely severe, but needs to be improved. I'm concerned mostly about hypopigmentation. I am a white male, 37, with fair to somewhat darker skin tone. I think my dermatologist called it a 2 out of 5? What should I know about the possible permanent change in skin color?

Hypopigmentation has a low risk

Hypopigmentation after CO2 laser skin resurfacing has a low risk. This is especially true if done in a fractionated manner and not one laser treatment under general anesthesia.

The Fraxel 1540 laser-although called nonablative is mildly ablative but I have not seen any cases of permanent discoloration. The Pixel CO2laser has also drastically lowered the risk of discoloration which I have not seen to date but can occur. There is always a risk of skin color change but use of Hydroquinone and sunscreens may further lessen the risk.

Hypopigmentation after CO2 laser no longer an issue.

The original CO2 lasers (15 years ago) did a nice job on wrinkles and acne scars but did cause loss of pigment in a large minority of patients. The pigment loss generally did not appear for a year after the CO2 laser treatment. This is no longer a problem with the fractional CO2 lasers. The fractional lasers (Active FX, Fraxel and others) treat less than 100% of the surface area of the face leaving untouched cells that result in rapid healing and elimination of the... more

Fractional non-ablative Erbium laser resurfacing is more effective for acne scars

CO2 laser resurfacing treats the surface of the skin and does carry a 10% risk of hypopigmentation and demarcation lines next to untreated areas. Correction of acne scars requires the production of new collagen in the deep skin layers. New fractional non-ablative 1540 Erbium laser resurfacing is much more effective at building new collagen in the deep skin layers, and thus is much more effective at correcting acne scars. Non-ablative fractional 1540 Erbium laser resurfacing is also much... more
