Laser Treatments
There are 2 major categories of laser used in acne scar therapy. They are the resurfacing (aka ablative) lasers and the non-ablative lasers.
Ablative lasers literally remove the outer layers of the skin, burning away scar tissue and stimulating the dermal collagen to tighten, reducing the amount of scar visibility. The ultrapulsed carbon dioxide laser and erbium YAG laser are most frequently used in laser resurfacing.
Because the skin is injured and unprotected tissue exposed, great effort must be put into wound care and infection prevention. The skin may remain reddened for several months or a year afterwards.
Non-ablative lasers trigger changes within the dermis without injuring the epidermis. They are the "lunchtime" form of laser therapy. Smoothbeam is the newest FDA approved laser for this treatment. Smoothbeam targets and heats the sebaceous gland, helping reduce sebum and acne formation. Heating the collagen helps tighten the dermis, resulting in less visible scarring.

Another option is the yellow pulse dye laser. The yellow light laser also helps treat keloidal scars, flattening and reducing redness as well as helping control itching of the raised scar.
A topical anesthetic like LMX 4% Topical Anesthetic Cream - 30gm is applied about an hour before the procedure. The surface of the skin is cooled to prevent the laser from damaging the epidermis. A patient will feel both the cold spray as well as some amount of stinging and heat during the session. The application of a topical anesthetic an hour before the procedure makes this tolerable. The procedure takes about an hour. Typically 3 sessions a month apart are performed.
Another non-ablative laser, the N-Lite is used to trigger collagen formation. Three or more treatments may also be required to obtain acceptable improvement.
