Medical devices based on light-emitting diodes (LEDs) are a secure means of treating various ailments, including skin inflammation, ageing, and skin-related illness. The current study examines LED-based treatment strategies for various skin conditions. In this proposed system, a phototherapy device treats acute and chronic wounds by delaying the growth of cells impacted by dermatological conditions including psoriasis and dermatitis, and promoting new healthy cell growth by employing an LED patch. This apparatus accelerates the proliferation of fibroblasts in the injured and afflicted areas. Under several light irradiation methodologies, the wound healing test on normal human fibroblasts demonstrated that the LED light had no harmful effect, with strong fibroblast proliferation and migration (over 10–20% compared to control). Experiments on cell migration and proliferation demonstrate the need for adjusting radiation dosages and LED wavelengths for improved clinical evaluation. The LED patch creates enormous prospects for the economic development of a future portable healthcare system.
