Although there are advocates for each of these technologies, there is no question that both lead to clinical improvement.^1-2 Unfortunately, ablative techniques are sometimes accompanied by adverse effects and complications. The most common of these is postoperative erythema, an adverse effect that is experienced by virtually all patients who are treated with these modalities. Other potential risks induced by ablative dermal wounding modalities are infections, delayed healing, postoperative pigmentary changes, and scarring.

If dermal wound formation and new collagen formation are the primary mechanisms behind the improvement seen after laser resurfacing, techniques that induce a dermal wound without epidermal ablation should theoretically also lead to cosmetic improvement of dermal photodamage. The primary purported mechanism responsible for the effect of nonablative treatments is thermal denaturation of collagen associated with unwinding of the . . . [Full Text of this Article]
