Does red light therapy clear scars?

Yes, Red light therapy (RLT) can help reduce the appearance of scars by promoting healing and reducing inflammation. It stimulates collagen production, which is crucial for skin repair and elasticity, and improves circulation, enhancing nutrient delivery to the scarred area. Although RLT shows promise in diminishing the visibility of scars, its effectiveness can vary based on scar type, age, and individual skin response. For optimal results, consistent use over several weeks or months is often necessary.

2. Enhancing blood circulation: Boosts nutrient and oxygen supply to scar tissue, promoting faster healing.
3. Reducing inflammation and redness: Minimizes swelling and discoloration, making scars less prominent.
4. Improving skin texture and tone: Smooths and evens out the skin, aiding overall appearance.
