How to cure strechmarks?

Laser therapy. Stretchmarks, or striae distensae, can be treated with fractional photothermolysis (fp). Fp uses small laser beams to create numerous microscopic areas of thermal necrosis within the skin called microscopic treatment zones. It is also used to treat acne scars, photodamaged skin, and fine wrinkles.
Vitamin E. There really is no good cure. You can try vitamin E cream. It has worked for some of my patients.
