Does red and blue light harm the skin?

Although red and blue light can remove acne and promote skin elasticity, red and blue light cannot be exposed to the skin for a long time, as it may cause skin cancer or aging, and may also burn the skin. Therefore, everyone should pay attention to the exposure time of red and blue light. When red and blue light are irradiated on the skin on a regular basis, it can promote the synthesis of collagen in the skin, promote cell growth, and help restore skin sagging.

Precautions

The red and blue light therapy device uses high-purity, high-power density red light, blue light and yellow light to irradiate the skin, which can change the cell structure, kill bacteria, provide a suitable environment for new cells, enhance the production of new collagen elastin and collagen, and promote cell growth; it can repair inflammatory acne, aging skin, relieve sunburn without damaging the skin, and can whiten the skin and promote skin elasticity. What are the precautions before red and blue light acne treatment?

1. Before the operation, pay attention to continuous sun protection, eat less greasy and spicy food, and keep a happy mood.

2. In the first 3 to 4 days after the operation, focus on "repair" work, try to wash your face with non-irritating facial cleanser, keep the affected area clean and refreshed, apply some restorative ointment prescribed by the doctor, and take some oral anti-inflammatory drugs and antibiotics.

3. After a week, the wound will begin to scab and fall off. At this time, sun protection is an absolutely essential step. Apply SPF 20 to 30 sunscreen when going out, and protect yourself from the sun for at least 3 to 6 months.

4. If you have any abnormal condition, consult your doctor and never make decisions on your own to avoid an irreparable situation.

side effect

Red and blue light are specifically used to kill Propionibacterium acnes that causes acne. It only needs to be irradiated on the skin for fifteen minutes and only targets acne. The light is very gentle and can be used on sensitive skin without any side effects. You don’t need to worry about the side effects of red and blue light acne removal.

Therapeutic Device

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.
