Does Chemical Peel After Laser Resurfacing Help?

New collagen will continue to form 3 to 6 months after ablative laser resurfacing.  To maintain the effects of the laser treatment, you should have light chemical peels or microdermabrasion to keep stimulating some collagen.  These can be started after 3 months.  You should also consider using tretinoin cream and you must use sun protection.

I would agree that chemical resurfacing after laser resurfacing would be redundant. If you have depressed, ice-pick scarring, there are other treatments that can manage what the re-surfacing procedures cannot address, including saline subcision, punch excision followed by resurfacing and the TCA Cross method in which strong chemical peeling agents are applied to individual depressed scars. If you really want to undergo another resurfacing procedure, I would wait 6 months since improvement in scars following the laser resurfacing procedure you just undertook can continue for several months.

Ablative laser resurfacing and chemical peeling can only improve superfiical scarring. Most noticeable scar improvement requires stimulation of new collagen growth deep in the Dermis; Chemical peels and Active FX just cannot do this.
The best, newest, most effective treatment for scars is called non-ablative fractional laser skin resurfacing. There is no raw skin or down time afterwards. I use the Starlux 1540 laser and the results on scars are very good. You will need 4 treatments a month apart.
Be sure to find an expert doctor who knows how to treat scars with this new technique. You can learn more by visiting the palomar medical website. A chemical peel would be a waste of time and money to treat scars.

If you have recently had laser resurfacing, there usually would not be any reason to go through further resurfacing using a chemical peel. Maybe there might be a few instances where this could be entertained but it certainly isn't the routine practice.
