Fraxel is a great laser for treating scars, hyperpigmentation and other forms of sun damage. Stretch marks are difficult to treat. I don't know what settings were used on your arms or what your natural skin type is from the small photo. I prefer eMatrix laser for stretch marks since it does not run the risk of hyperpigmentation. Please consult a board certified dermatologist for evaluation and treatment of your arms.

Hyperpigmentation after Fraxel for stretch marks is treated with hydroquinones
Hyperpigmentation after laser is more common in darker skin types and people with a lot of sun exposure. I can be treated most often with hydroquinones 4%. If not improving, adding Retin A +/- a steroid cream. It almost always resolves. A better, newer treatment for stretch marks, particularly darker skin types, is the Infini RF device. I would try it, but not many docs have it presently. Steve Weiner, MD, Facial Plastics, Destin, Fl
