How effective is red and blue light therapy for acne, exactly?

1. Blue-light therapy for acne removal works through a series of natural physical processes, including eliminating acne-causing bacteria, altering the intracellular pH, and—most importantly—improving the immune system’s function. 2. Because of these mechanisms, the treatment delivers noticeable results, and the effects persist even after the treatment is discontinued, making recurrence less likely. It is an effective photodynamic therapy approach. 3. Combined red-and-blue-light therapy for inflammatory acne: Combining blue light and red light to treat acne represents a novel therapeutic approach. This method can effectively clear inflammatory and cystic acne lesions while also enhancing immune system function. Blue light: has antibacterial properties and helps regulate the immune system. When used alone, blue light therapy can reduce inflammatory lesions by an average of 73%. Red light: has anti-inflammatory effects and can reduce the likelihood of acne scars forming. The average clearance rate for acne using red light is 82%. In addition to using red and blue light for acne treatment, patients can also opt for professional pharmaceutical treatments. For those with mild acne symptoms, topical clindamycin phosphate gel is recommended; it exhibits strong antibacterial activity against Propionibacterium acnes and can also reduce fatty acids on the skin’s surface, thereby aiding in acne treatment. If symptoms are more severe, oral medications such as Compound Muniziqi Granules are suggested. These granules help regulate abnormal body fluids and constitution, detoxify the body, treat acne, and reduce acne scars. Meanwhile, Detoxification and Skin-Nourishing Capsules are beneficial for constipation, acne, and facial pigmentation caused by internal heat toxicity, promoting qi circulation and blood flow while reducing acne formation.
