Light Therapy Research – Skin & Dermatological Issues

A collection of light therapy research articles on the benefits of light therapy use for dermatological issues like psoriasis, scars, eczema, etc.

NOTE: Researchers use several terms to describe “light therapy”. Photobiomodulation, low level light therapy (LLLT), phototherapy, photon therapy, photo energy, heliotherapy, and sometimes red, blue or (near)infrared radiation are synonymous; they all refer to light therapy.

 

Light-Emitting Diode at 460 ± 20 nm Increases the Production of IL-12 and IL-6 in Murine Dendritic Cells.

A Systematic Review of Light Emitting Diode (LED) Phototherapy for Treatment of Psoriasis: An Emerging Therapeutic Modality.

May 1, 2017

This study aims to prove that combined wavelengths (blue, red & infrared) of LED light is a cost-effective, safe, and portable treatment option for psoriasis.

Light therapy is a fast growing technology for stimulating, healing, and restoring the skin
Harvard Medical School Department of Dermatology is encouraging further testing of light therapy for dermatological conditions, particularly due to the “noninvasive nature and almost complete absence of side effects”. This published article goes over some of the potential benefits of light therapy for the skin including wrinkles, acne, scars, psoriasis, and healing of burns.

Potential implication for light therapy in the management of Eczema
This study demonstrated that, combination therapy of low level light therapy (850 nm) and low-dose Tacrolimus, showed a significant reduction in the severity of skin lesions (AD-like skin lesions).

Light-based technologies introduce new ways to manage keloids and scars
Keloids and hypertrophic scars represent a large concern in the cosmetic industry, mainly for aesthetic reasons. This article reviewed all the recent literature and studies on both lasers and L.E.D. light therapy and showed that both applications of light proved to enhance patient outcomes, affecting quality of life.

Light therapy on scar tissue
Low level light therapy “showed a tendency to decrease older scars’ thickness”.

Light therapy helps sensitive skin
Sensitive skin represents a major concern, both medically and aesthetically for the general population, due to its high prevalence. In this study, skin cells were treated with sodium laurel sulfate. Following the addition of this chemical agent onto the skin, light therapy was applied and ALL patients showed both subjective and objective improvements from the light therapy. The results suggest that low level light therapy could be a useful and safe treatment modality for sensitive skin.

Low-Level Laser (Light) Therapy
 (LLLT) in Skin: Stimulating, Healing, Restoring

Low-level laser (light) therapy (LLLT) is a fast-growing technology used to treat a multitude of conditions that require stimulation of healing, relief of pain and inflammation, and restoration of function. Although skin is naturally exposed to lightmore than any other organ, it still responds well to red and near-infrared wavelengths.

Evaluation of Light-Emitting Diodes (LED) Effect on Skin Biology (in Vitro Study)

Interest in anti-aging approaches has grown significantly in recent years. The most popular are the non invasive methods to decrease the signs of aging. One such method is LED-based therapy.
