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

Acne has long been a persistent challenge for beauty-conscious women, as it not only leaves their skin uneven and bumpy but also makes their pores appear unusually large. They’ve typically tried numerous treatments, yet most have ended in failure. Recently, red-and-blue light therapy has become quite popular online for treating acne. But just how effective is it? Let’s find out together below!
The tool used for red and blue light therapy to treat acne is a red-and-blue light therapy device. This device uses high-purity, high-power-density red and blue light to irradiate the skin, which can alter cell structure, kill bacteria, and provide a favorable environment for new cell growth. It promotes the production of new collagen, elastin, and other connective tissues, thereby stimulating cell proliferation. Additionally, it helps repair inflamed acne-affected and aged skin, alleviates sunburned skin without causing any harm to the skin itself, and can brighten the complexion while enhancing skin elasticity.
The advantages of red-and-blue light therapy for acne primarily lie in providing patients with an alternative to oral antibiotic treatment for acne. The treatment process is pleasant, painless, requires no anesthesia, and demands no recovery time. It delivers rapid results—just eight sessions per course—and exhibits significant efficacy. It is safe and free of side effects. In addition, red light has excellent effects on skin rejuvenation and the treatment of other skin conditions.

Given these advantages, how effective is red and blue light therapy for acne?

1. Blue light therapy for acne removal works through a series of natural physical processes, including eliminating acne-causing bacteria, altering the pH level inside cells, and—most importantly—improving the immune system.
2. Because of these factors, the treatment delivers noticeable results, and the effects persist even after the treatment is discontinued, making relapse less likely. It is an effective photodynamic therapy method.
3. Combined Red and Blue Light Therapy for Inflammatory Acne: Combining blue light and red light to treat acne is a novel therapeutic approach. It can effectively eliminate inflammatory and cystic acne and improve immune function.
Blue light: bactericidal and immune-regulating. When used independently to treat acne, blue light can reduce inflammatory lesions by an average of 73%.
Red light: reduces inflammation and may help minimize the formation of acne scars. The average clearance rate for acne is 82%.
In addition to using red and blue light therapy for acne, patients can also opt for professional medications. For those with mild acne symptoms, topical clindamycin phosphate gel is a suitable choice. This gel exhibits strong antibacterial activity against Propionibacterium acnes and can also reduce the amount of fatty acids on the skin’s surface, thereby promoting acne treatment.
If the symptoms are severe, it is recommended to choose oral medications such as Compound Muniziqi Granules, which can regulate abnormal body fluids and constitution, helping to detoxify the body, treat acne, and fade acne scars. Meanwhile, Detoxification and Skin-Nourishing Capsules are beneficial for constipation, acne, and facial pigmentation caused by internal excess heat toxins, as they tonify qi, promote blood circulation, and reduce the formation of acne.
