Skin Rejuvenation by Low-Level Light Therapy

Skin Rejuvenation by Low-Level Light Therapy

Risk-Benefit Analysis

Low-level light therapy (LLLT) is the use of low incident levels of photon energy at a particular wavelength, targeting tissue to achieve a clinically useful local or systemic effect without the creation of heat (athermal) or damage (atraumatic) (Calderhead & Tanaka, 2017). LLLT has shown dramatic effects when used for wound healing, pain management, and various musculoskeletal conditions.

This review focuses on its potential use in skin rejuvenation. It has been shown that upon exposure to light, chromophores in the skin (mitochondrial cytochrome C, melanin, and protoporphyrins) absorb photons which lead to downstream alterations in physiology such as changes in cell proliferation, differentiation, migration, inflammatory mediators, and collagen production. It is supposed that these photobiomodulative effects have beneficial effects on the skin, leading to a more youthful appearance through increased collagen and elastin production, and a reduction in age spots and wrinkles. 

Key Questions 

This analysis seeks to answer the following questions:

  • Which benefits with regard to skin rejuvenation result from LLLT? 
  • Which risks are involved in using LLLT for skin rejuvenation (general and method-specific)?
  • What are the potential risk mitigation strategies?
  • Which method/device or combination of methods/devices is most effective for skin rejuvenation using LLLT?
  • Which of the available devices/methods are safe for use? 
  • What is the best therapeutic protocol available at the moment?

Medicinal Mushrooms (PDQ®)

“Medicinal mushrooms have been used for hundreds of years, mainly in Asian countries, for treatment of infections. More recently, they have also been used in the treatment of pulmonary diseases and cancer. Medicinal mushrooms have been approved adjuncts to standard cancer treatments in Japan and China for more than 30 years and have an extensive clinical history of safe use as single agents or combined with radiation therapy or chemotherapy.More than 100 species of medicinal mushrooms are used in Asia. Some of the more commonly used species include Ganoderma lucidum (reishi), Trametes versicolor or Coriolus versicolor (turkey tail), Lentinus edodes (shiitake), and Grifola frondosa (maitake).Studies have examined the effects of mushrooms on immune response pathways and on direct antitumor mechanisms. The immune effects are mediated through the mushrooms stimulation of innate immune cells, such as monocytes, natural killer cells, and dendritic cells. The activity is generally considered to be caused by the presence of high-molecular-weight polysaccharides in the mushrooms, although other constituents may also be involved. Clinical trials in cancer patients have demonstrated that G. lucidum products are generally well tolerated.[1]Many of the medical and scientific terms used in this summary are hypertext linked (at first use in each section) to the NCI Dictionary of Cancer Terms, which is oriented toward nonexperts.”
