Nonablative resurfacing with laser and lights warms the dermis and
can provide modest improvement of acne scarring by stimulating
collagen remodeling. All subtypes of acne scars can be improved by
nonablative therapy. Among the lasers used for this indication are
devices originally developed for otheruses, such as pulsed-dye lasers,
intense pulsed light devices, and Q-switched Nd:YAG lasers.
However, more recently nonablative devices have been optimized to
specifically target textural irregularities. For example, a series of
treatments with infrared lasers can significantly improve uneven
contour associated with acne scarring. These treatments are
typically uncomfortable and may require oral and/or topical
analgesics.
Similarly, fractional resurfacing is quite effective in the treatment of
acne scarring. Fractional resurfacing is a minimally ablative technique
that creates microscopic zones of dermal injury in a grid-like pattern.
Because only a small proportion of the skin surface is treated at
one time, and since the stratum corneum is not perforated, recovery
is quick. However, a series of treatments is needed...consult dermatologist they will do the needful
