Does blue light therapy work for acne?
According to the American Academy of Dermatology, light therapies "show great promise in treating acne," with many people experiencing a significant improvement in their skin health after a number of sessions.
Blue light therapy can be used to treat acne that is already present on the skin or to control the condition before an outbreak occurs.
However, the academy warns that acne does not usually completely clear up with phototherapy alone.
Additional treatments are often needed to manage acne symptoms fully.
