Unfortunately, the one photo does not permit an adequate assessment of the problem. Ideally, an up-close, in-person examination that allows for palpation and manipulation of the skin would allow for better evaluation. Although surgery may be used for significant laxity, it would be less desirable in milder cases, as scarring from the surgery itself can be at least as disfiguring. Radiofrequency, fraxel laser and ultrasound devices remain, to date, far more backed by device manufacturer backed marketing hype than hard science. The injection of hyaluronic acid based bioremodeling agents, such as Profhilo alone or in combination with injectable hyaluronic acid based "skin boosters," such as Viscoderm Hydroboosters has proven quite helpful for treating laxity of the upper arms, as well as for the thighs. Although these two products are not yet available in the U.S., a skin booster agent, Restylane Silk is. Typically two to three treatment sessions are required at monthly intervals to achieve maximal response. You might wish to discuss this option with a board certified aesthetic physician before embarking upon device treatments, which are likely to be costly and disappointing. Best of luck.
