LED light-therapy for acne and pimples

LED light-therapy, also known as photodynamic therapy, is very popular in skin care nowadays. Whether done at home or in a dermatologist’s office, LED light-therapy can improve acne, decrease oil production, and even soothe inflammation no matter the skin color.

There are two types of lights: blue light and red light. Both are believed to target different triggers. Blue light is anti-bacterial and the red light can briefly reduce oil production in sebaceous glands.



Blue Light

The specific wavelength of blue LED light can remove a major trigger of acne and pimples while calming the skin and diminishing oily skin at the same time. Bacteria are very sensitive to the blue light spectrum. It can shut down their metabolism and kill them. The light penetrates the skin’s hair follicles and pores which harbor bacteria and cause inflammation, and acne.



Red Light

Red light, on the other hand, can help reduce inflammation associated with acne. Most often it is used for anti-aging purposes because it can stimulate the production of collagen in the skin. At the same time, it can help reduce inflammation. It can also work on a different acne trigger. For many who have acne, their oil contains inflammatory substances that pave the way for acne to pop up on the surface. So, the red-light therapy can help reduce the inflammations and calm the factors that help trigger acne. Plus, this light can reduce the redness caused by the acne and breakouts.


In the end, both lights have been shown to improve the overall skin's health, without any or minimal side effects. The downside is that they need to be used several times a day. But this is a better alternative than trying to pick or pop a pimple, which aggravates acne and increases the risk of scarring.
