The Cosmetic Vein and Laser Center estimates the cost of stretch mark laser therapy to be anywhere from $100 to $2,000 per treatment, as of 2015. The American Society of Plastic Surgeons notes that nonablative procedures in 2012 averaged approximately $1,100 in costs, with ablative laser skin resurfacing costing twice that.
Laser skin resurfacing treatments for stretch marks typically involve yellow light and other advanced lasers, according to the Cosmetic Vein and Laser Center. The cost of each treatment depends on the amount of skin being treated during a single session. While lasers have the ability to improve the look of stretch marks in some people, lasers cannot completely erase stretch marks, notes About.com. Stretch marks are the result of permanent changes to the deep epidermis layer underneath the skin's surface. Studies show that lasers may improve younger red stretch marks, but are practically useless for mature white stretch marks.
Laser skin resurfacing treatments are not recommended for people with darker skin tones, because treatments may cause hyperpigmentation of the skin, reports About.com. Ablative lasers are more invasive laser skin treatments than nonablative, and risks associated with both treatments include infection, skin color changes and scarring, explains Straith Clinic. Nonablative lasers produce modest results, but patients experience little downtime and fewer side effects.
