Discover how light therapy promotes faster wound healing by reducing inflammation and stimulating tissue regeneration effectively.
I remember coming home with a new bruise or cut almost every day after childhood basketball practice. Cuts and bruises came with the game, yet my mother never dismissed them as trivial.
They may look minor, but even a small wound can matter. An open cut gives external bacteria a way in, so prompt care helps lower infection risk.
Do you know what actually occurs when the skin is sliced?
In a shallow cut only the dermis is pierced and small vessels are injured. A deep cut reaches underlying tissues and severs larger vessels, causing noticeable bleeding.
Within minutes, clot-forming cells and immune sentinels such as neutrophils converge on the area. Proteins and antibodies clear debris, then fibroblasts rebuild tissue and lay down new capillaries. The final phase remodels the repaired vessels and fibers so they regain strength and flexibility.

Science keeps adding tools to everyday medicine; one of them is light therapy.
Low-level red and near-infrared light can support healing in stubborn or slow-healing wounds such as:
• Diabetic ulcers
• Venous ulcers
• Pressure ulcers
• Non-healing surgical incisions
• Serious burns
• Oral mucositis from chemotherapy or radiation
• Metabolic-disease-related wounds
• Wounds that repeatedly break down
Devices deliver red (620–680 nm) and near-infrared (700–1100 nm) photons. Laboratory work suggests that irradiated skin cells can multiply up to twice as fast as non-irradiated controls, probably because the light boosts micro-circulation and cellular energy (ATP). Better blood flow brings oxygen and nutrients, while improved lymphatic activity removes waste, keeping the wound environment clean.
