When your pores are blocked, and the bacterias that have all the time exist in your pores and skin will feast on the mixture. In other words they will try to survive a little bit longer by consuming the sebum, which is a kind of oil. The bacterias will then infect your pores and cause acne breakouts.
It was discovered that a number of the violet (or blue) light visible from the sunlight, within a range of 405 to 420 nanometers, activates the Coproporphyrin III found in the acne-causing bacteria, Propionibacterium acnes. The porphyrin destroys and kills the culprit bacteria as it releases singlet oxygen. An amount of 320 Joules per square centimeter of light in the 405-420 nm range prevents the survival and viability of the bacteria. This portion of the light spectrum, which is outside the sun's ultraviolet spectrum, produces minimal sunburn or tanning.
People having acne should seek dermatological care before trying anything on them just because it worked on some else. This is simply because there are different reasons as to why someone may suffer from it. Sometimes it's attributed to body hormone imbalances, diet, excessive salt intake, changes in humidity and high levels of calcium and magnesium. Male and female generally suffer from genetic related and stress related acne.
