I recommend LED Light Therapy to treat body acne because the results speak for itself.

Blue wavelengths kill the bacteria that causes acne breakouts, while reducing the inflammation, pimples and redness associated with acne. A reduction in lesions and overall improvement in skin appearance is often seen in only a matter of weeks. Of course, outcomes vary depending on severity of the condition and compliance to recommended protocols.

I use a device with a flexible design.  It is able to mold to the treatment area to improve cellular performance on a microscopic level. Skin cells are able to absorb even more light energy in less time, speeding up the acne elimination and skin healing process. Because of the ability to place the device close to the skin, this device outperforms many even more expensive devices that cannot wrap around the treatment area.

I use a device from Celluma that is FDA cleared for the treatment of acne.
