Stretch marks are linear stripes in the skin that occur when the subcutaneous connective tissue tears during mechanical stretching. Occurrence of stretch marks most often are caused by certain changes of body shape: pregnancy, breastfeeding, rapid growth during puberty, strong skin stretching caused by  weight gain, and also prolonged administration of certain medications (anabolic steroids, oral and topical glucocorticosteroids). The most common stretch mark locations include thighs, abdomen, breasts, and buttocks. Despite stretch marks do not pose any serious health risks, the majority of patients are willing to remove stretch marks for aesthetic and other reasons that cause discomfort.

Laser treatment for stretch marks is a procedure when a laser beam stimulates collagen production inside the skin and cell regeneration in the affected area to increase skin elasticity and "fill" the stretch marks with new collagen. Gradually, stretch marks become less visible leaving the skin more supple, more elastic, and smoother.

Usually, the procedure must be repeated few times depending on the length and width of stretch marks as well as the affected area, therefore the exact number of sessions can only be determined by a dermatovenerologist during the course of the treatment. It is important to know that the earlier you start treatment after occurrence of stretch marks, the better results can be achieved during treatment.
