naturlase

Naturlase is a technology that integrates low‑intensity laser emitters with biological tissues to facilitate natural healing processes. The system uses wavelengths in the near‑infrared range (typically 600–900 nm) to stimulate cellular activity, enhance circulation, and accelerate tissue repair without the need for invasive procedures.

The concept was first introduced by Dr. Anders Karlsson, a Swedish physiotherapist, in the early 2000s while studying the effects of laser therapy on skin regeneration. In 2005, the company Naturlase AB was founded in Gothenburg, Sweden, to commercialize the technology. Patents covering the specific laser-tissue interaction protocol were filed in the European Patent Office and later in the United States. The product line expanded from handheld devices for home use to larger units for clinical settings by 2010.

Naturlase devices are employed in a range of medical and aesthetic applications, including treatment of chronic wounds, tendon injuries, and inflammatory conditions. They are also marketed for cosmetic use such as hair growth stimulation and skin rejuvenation. Clinical trials published in journals such as the Journal of Photochemistry and Photobiology have reported modest improvements in healing times, but results vary widely across studies.

Critics argue that the evidence base for Naturlase remains incomplete, citing small sample sizes and lack of double‑blind controls in many studies. Additionally, concerns have been raised about regulatory oversight in countries where the devices are sold over the counter. The technology is currently regulated as a medical device in the European Union and requires clearance before use in therapeutic contexts.

Related topics include low‑level laser therapy, photobiomodulation, and regenerative medicine. The role of Naturlase within these fields continues to be evaluated by researchers and clinicians seeking non‑pharmacologic treatment options.
