How Light Therapy Treats Acne
Acne forms in our skins pores, the tiny holes in your skin. Each pore contains an oil-producing gland called a sebaceous gland. The oil is good for our skin as it helps to keep our skin youthful and healthy but sometimes our sebaceous glands can overproduce oil and the excess oil, dirt, and dead skin cells can get trapped inside pores and clog them up. Bacteria called Propionibacterium acnes (P. acnes) that live on your skin can also get inside these blocked pores. P. acnes make the clogged pores swell up into bumps called acne.
One way to kill the bacteria and clear up pimples is with light therapy. The bacteria in your skin are sensitive to the blue light spectrum. Research shows that blue light penetrates skins hair follicles and pores, unlike topical treatments that work to ease inflammation and bacteria on the surface of the skin. When the blue lights are on your skin, substances form that kill the bacteria before it begins to feed on the oil glands. Light therapy also shrinks the oil glands in your skin, so your skin produces less pore-clogging oil, preventing future breakouts.
I recommend also using Red Light as an acne treatment in combination with Blue Light because it works to soothe inflammation and redness.
