How does LED Light help acne?
Blue LED at the wavelength 470nm uses light energy to kill bacteria.
LED assists with killing p.acnes bacteria by using a byproduct from the bacteria called porphyrin against itself. “When porphyrins absorb light of certain wavelengths, free radical damage is produced, and this destroys the bacteria. Blue light acne treatment uses a narrow-band, high-intensity blue light source that is readily absorbed by porphyrins released by the bacteria causing acne.” (source www.dermnetnz.org) This is NOT a cure for acne since Acne is NOT caused by bacteria. Inflamed acne, for example, pustules, papules and cysts are a SYMPTOM of the skin disorder. That is why just killing bacteria is not a cure for it.
Acne results from an inflammatory cascade of events that occur. Inflammation occurs at a cellular level along with a “sticky” sebum that helps trap skin that exfoliates off the lining of the pore in “normal” people. An acne prone individual may even “exfoliate” off up to 5 layers of dead skin cells per day. The term hyperkeratization is too many dead skin cells coming off the lining of the pore.
Why does that happens? Science speculates that a certain genetic predisposition occurs in some people along with diets higher in sugar, acne inflammatory foods such as dairy products and high B-Vitamin Foods to name a few. (We’ll talk about how high doses of certain B-Vitamins help to increase acne on a later date.) In addition to this, high iodine diets or high salt diets (sea salt is fine), can exacerbate acne.
In addition to this we add on hair products like shampoo, conditioner and styling aids that have acne irritating ingredients in them. Then, we use make up with those same acne irritating ingredients. There is more, but that is why I am here to help!
