Red and blue light treatment for acne]
I. What is acne?
Acne is a chronic inflammatory skin disease that mostly begins in adolescence and occurs in the sebaceous glands of hair follicles. It also occurs in middle-aged women and is most common on the face and chest and back, with characteristic acne, papules, pustules, cysts, nodules and other damage.
Malignant acne: It occurs in weak individuals with lesions of papules, pustules and nodules, and has a long and persistent course.
Eruptive acne: Occasionally seen in young men, many lesions with heavy inflammation suddenly appear, forming nodules and ulcers, in addition to local pain and discomfort, accompanied by generalized fever and multiple joint pains, with obvious scarring left behind at a later stage.
Second, what is the principle of red and blue light treatment for acne?
Red and blue light treatment for acne, also known as combined red and blue light treatment, is mainly used to treat mild to moderate acne. Red light has the longest wavelength and deepest penetration ability among visible light, and can penetrate 8-10mm deep under the dermis, so it is most widely used. Red light can stimulate the body and increase the activity of immune cells for the purpose of anti-inflammation and skin repair. When blue light is used to remove acne, it penetrates to the deeper layer of the skin where Propionibacterium acnes is located, rapidly killing Propionibacterium acnes on the skin surface and in the glands, inhibiting sebaceous gland secretion, reducing the number of acne and inflammatory lesions, and promoting tissue repair.
C. What are the treatment and interval times for red and blue light treatment of acne?
Five sessions of red and blue light treatment for acne is a course of treatment. Generally, one course of treatment is sufficient for milder cases, while more severe cases can receive multiple courses of treatment with an interval of 2-3 days each time.
