What is the use of blue light for acne

As long as we have acne on our face, we will feel troubled, especially for girls. Having acne means that your skin is in poor condition, and you cannot wear makeup when you have acne. There are many tips for removing acne on the Internet, and many people will follow them, but these methods require a lot of time and energy. Some people suggest that you can use blue light to treat acne. What is the use of using blue light to treat acne?

It can remove acne. Red and blue light acne removal is based on the blue light acting on the surface of the skin, killing Propionibacterium acnes and playing an antibacterial and anti-inflammatory role. It can also effectively inhibit the secretion of sebaceous glands and prevent the recurrence of acne; while red light can pass through the surface tissue of the skin, act on scar tissue, prompting cells to secrete collagen and play a role in removing acne marks and repairing acne scars.

Acne removal mechanism

1. First of all, red and blue light acne removal takes a short time and is effective quickly. A single treatment only takes about 30 minutes, and you can see obvious acne removal effects after one course of treatment. It is simple and quick, and there is no need to take a day off during treatment.

2. The treatment process is safe and has no side effects. It will not cause drug resistance or dependence. There is no irritation to the skin and the treatment process is painless.

3. Red and blue light is a more gentle pulse light. Its treatment process has no thermal effect and can avoid thermal damage to the skin.

The red and blue light therapy device uses a narrow spectrum light source to emit a cold light that does not generate high heat and will not burn the skin. It converts light energy into intracellular energy and is one of the safest and most effective instruments for treating acne and skin rejuvenation.

Studies have shown that mixed red and blue light exposure can reach 35.7%, which is much higher than the single blue light exposure group (8.3%) (P=0.008). Severe acne has a more obvious reaction than moderate acne, and the side effects are minimal. The use of blue light can produce an effect on inflammatory reactions, and the therapeutic effect is better than using red light alone, with no obvious side effects. Conclusion: Red-blue light combined treatment of acne can achieve ideal therapeutic effects and is suitable for the treatment of patients with mild and severe acne.

Therapeutic effect:

1. Blue light removes acne through a series of natural physical processes, including eliminating acne bacteria, changing the pH value inside cells, and more importantly, improving the immune mechanism.

2. Because of these, the effect is obvious during the treatment process, and after stopping the treatment, the effect will continue and will not recur easily. It is an effective photodynamic method.

3. Independent application of blue light to treat acne can reduce inflammatory lesions by an average of 73%.

Combining blue and red light to treat acne is a new treatment approach. It can effectively clear inflammatory and cystic acne and improve the immune mechanism.

Blue light: kills bacteria and regulates the immune system.

Red light: Anti-inflammatory, can reduce the possibility of acne scarring.

The average clearance rate for acne is 82%.
