BACKGROUND

Nonablative resurfacing, also referred to as subsurface or dermal remodeling, is a recently introduced technology for restoring damaged collagen without injuring or removing the overlying epidermis. To date there have been no published comparisons or reviews of these laser systems.

OBJECTIVE

The authors review the mechanisms of action of currently available nonablative laser technologies and published data on their performance.

METHODS

Literature concerning nonablative laser technology published between 2000 and 2002 was reviewed by use of Medline searches. Data on technical specifications were obtained from the manufacturers.

RESULTS

Significant improvement in skin elasticity and photodamage with few or no complications was noted after treatment with most of the systems reviewed. However, the results were generally more subtle than those achieved with ablative lasers.

CONCLUSIONS

Nonablative technology is currently at the forefront of skin rejuvenation. Data on long-term results must await several more years of accumulated clinical treatment. Improvement in skin quality, tone, and texture can be expected, but patients and physicians who expect nonablative laser treatment results to be similar to those achieved by ablative techniques may be disappointed.
