Understanding Acne Spots

Acne spots are a chronic inflammatory skin disease that mainly accumulates in the sebaceous cells of the hair follicle. Acne is a disfiguring disease. If not treated in time or squeezed by itself, it will cause serious consequences and even disfigurement. Mild acne may be left with temporary pigmentation after healing, while severe acne can leave dimpled or hypertrophic scars that affect the appearance of the skin.

Causes of Acne Spots

  • Excessive sebum secretion (local androgen elevation): Oily skin is generallymore prone to breakouts than dry skin. After puberty, the level of androgens, especially testosterone, rises rapidly in the human body, which promotes the development of sebaceous glands and produces large amounts of sebum. The secreted oil needs to be excreted from the pores to the skin's surface. If the oil cannot be discharged and accumulates in the pores, sebaceous plugs will form to block the pores, causing acne spots.
  • Abnormal keratinization of the sebaceous glandsof the hair follicle causes impaired sebum excretion, resulting in the formation of keratin plugs. In addition to sebum that can clog pores, there is also a thick stratum corneum, external dust, greasy skin care products, cosmetics, etc., which may clog pores, which will form acne!

 

  • Inflammatory reaction:When you don't get good sun protection, UV rays can cause skin inflammation first and then slowly turn from inflammation to injury. This kind of damage is sometimes invisible to the naked eye, and if the inflammation encounters a variety of microorganisms, especially Propionibacterium acnes, it will eventually induce an inflammatory reaction and cause acne.

Acne Spots Treatment

There are several treatment options available for treating acne, such as topical creams like tretinoin, oral medications, etc. Conventional treatments can be effective, but they may not always provide the desired results. For a long time, dermatologists have paid less attention to the treatment of post-inflammatory skin lesions, including acne scars and acne pits. Among light therapy, blue light therapy is a popular method among doctors and patients' treatments for acne. Compared to intense pulsed light and lasers, blue light therapy is not so irritating and has been verified to be safe and effective.

What is Blue Light Therapy?

The wavelength of blue light therapy is high-energy short light between 400-500 nm. Its wavelength is close to ultraviolet light, which can be divided into natural blue light and artificial blue light, according to the source. Natural blue light comes from sunlight, and artificial blue light comes from a variety of electronic devices in life.

How Blue Light Therapy Works for Acne Spots?

With a wavelength of about 420nm, it acts on the superficial layer of the skin and quickly kills Propionibacterium acnes (P. acnes) by exciting the porphyrins within the bacteria. It changes the pH value inside cells, which plays an antibacterial and anti-inflammatory role. It can also effectively inhibit the secretion of sebaceous gland oil and prevent the recurrence of pimples. The blue light therapy device uses high-purity, high-power density light to irradiate the skin, which can change the structure of skin tissue, kill bacteria, provide a suitable environment for new cells, and repair inflammatory acne.

Blue light therapy is a non-invasive and gentle approach, unlike conventional treatments that can be harsh on the skin.

Blue light therapy can be an effective alternative for individuals who have developed antibiotic resistance or are looking for a drug-free solution.

Blue light therapy can not eliminate acne once. Doing it once only has a certain acne effect, but the treatment effect also needs to be judged according to the degree of inflammation. It is best to do a course of treatment. Generally, you can take it once every 1-2 weeks; after using it 5 times, redness, scars, swelling, and inflamed acne can be eliminated.
