This study from the American Academy of Dermatology found that with regular use psoriasis was reduced in a number of patients.
“…The researchers concluded that blue-light treatment is safe to use at home and can reduce psoriasis for some patients…”

“The clinical and histological effect of home-use, combination blue-red LED phototherapy for mild-to-moderate acne vulgaris…”
“…around half of a group of 35 people in Korea used a light therapy device combining blue and red light twice daily for 4 weeks.
They underwent evaluation after 12 weeks, while the other half used a placebo device.
Those who used the light therapy device saw a 77% improvement in inflammatory lesions and a 54% improvement in noninflammatory lesions.”

Note: If you are prone to acne leaving dark scars, blue LED light can worsen/darken some scars.
“The study showed that daily self-treatment using the device for mild-to-moderate inflammatory acne reduced the number of acne lesions significantly. Moreover, the study demonstrated a significant improvement of the subjects’ skin conditions. Subjects included in the study were able to, safely and effectively, administer self-treatment with the device and felt confident doing so.”

Blue LED light is most often used to treat acne. It may do this by reducing activity in the sebaceous glands, so they produce less of the oil that can plug the hair follicles, leading to acne.
Blue light may also kill acne-causing bacteria known as Cutibacterium acnes.
Often blue and red light are used in combination to help fight acne — the blue light targeting the C. acnes and the red light targeting inflammation and redness.”

“Red and blue lights are typically promoted in LED skin treatments. Experts believe that red LED light acts on cells in the skin known as fibroblasts, which play a role in production of collagen, a protein that makes up a large part of connective tissue and helps the skin to recover when it’s harmed.
So, in theory, red light could help to reverse some of the signs related to photoaging in the skin, says Dr. Buzney.
In addition, some studies show that red light may help to restore hair for those with androgenetic alopecia, or male- and female pattern hair loss …”
