Biophotonic pretreatment enhances the targeting of senile lentigines with a 694 nm QS-ruby laser

Fluorescent light energy modulates healing in skin grafted mouse model

Skin grafting is often the only treatment for skin trauma when large areas of tissue are affected. This surgical intervention damages the deeper dermal layers of the skin with implications for wound healing and a risk of scar development. Photobiomodulation (PBM) therapy modulates biological processes in different tissues, with a positive effect on many cell types and pathways essential for wound healing. This study investigated the effect of fluorescent light energy (FLE) therapy, a novel type of PBM, on healing after skin grafting in a dermal fibrotic mouse model. Split-thickness human skin grafts were transplanted onto full-thickness excisional wounds on nude mice. Treated wounds were monitored, and excised xenografts were examined to assess healing and pathophysiological processes essential for developing chronic wounds or scarring. Results demonstrated that FLE treatment initially accelerated re-epithelialization and rete ridge formation, while later reduced neovascularization, collagen deposition, myofibroblast and mast cell accumulation, and connective tissue growth factor expression. While there was no visible difference in gross morphology, we found that FLE treatment promoted a balanced collagen remodeling. Collectively, these findings suggest that FLE has a conceivable effect at balancing healing after skin grafting, which reduces the risk of infections, chronic wound development, and fibrotic scarring.

Evaluation of Fluorescent Light Energy for the Treatment of Acute Second-degree Burns

INTRODUCTION

The use of photobiomodulation has been proposed to improve wound healing for the last two decades. Recent development in photobiomodulation has led to the development of a novel biophotonic platform that utilizes fluorescent light energy (FLE) within the visible spectrum of light for healing of skin inflammation and wounds.

MATERIALS AND METHODS

In this article, FLE was used in preliminary analysis on 18 case studies of acute second-degree burns and in a pilot study using an ex vivo human skin model. Efficacy of FLE on wound healing and tissue remodeling was evaluated by monitoring improvements in the treated tissues, assessing pain for the patients, and by performing human genome microarray analysis of FLE-treated human skin samples.

RESULTS

Healing was reported for all 18 patients treated with FLE for acute second-degree burns without reported adverse effects or development of infections. Furthermore, preliminary ex vivo skin model data suggest that FLE impacts different cellular pathways including essential immune-modulatory mechanisms.

CONCLUSIONS

The results presented in this article are encouraging and suggest that FLE balances different stages of wound healing, which opens the door to initiating randomized controlled clinical trials for establishing the efficacy of FLE treatment in different phases of wound healing of second-degree burns.

Fluorescent light energy combined with systemic isotretinoin: A 52-week follow-up evaluating efficacy and safety in treatment of moderate-severe acne

Fluorescent light energy therapy combined with low-dose isotretinoin or tetracycline show remarkable clinical effect on 12 cases of moderate-to-severe acne. Treatment was considered safe, well-tolerated, and highly efficacious.

Effective removal of solar lentigines by combination of pre- And post-fluorescent light energy treatment with picosecond laser treatment

We present a novel treatment for removal of SL that is efficient and enables removal or lesions not immediately visible. Kleresca® FLE technology combined with picosecond laser treatment removes SL lesions and improves skin quality and appearance.
