The Palomar Icon 1540 non-ablative fractional laser is a great option for skin resurfacing and the treatment of surgical scars, acne scars, and stretch marks. It is the only FDA cleared laser for this treatment. 

This laser delivers light to the skin through high precision microbeams that penetrate the skin deep into the dermis. The microbeams create narrow, deep columns of skin coagulation, surrounded by healthy, untreated skin. This causes the skin to repair itself by replacing old, sun-damaged skin with new, younger, healthier skin. The 1540 fractional resurfacing is less invasive than ablative laser procedures, so it results in faster recovery time. 

The downtime is usually minimal with some mild redness and swelling for 3-7 days after a procedure. 

Generally, 3-5 sessions are recommended for optimal results.
