Does Blue Light really work for Acne?Updated 3 days ago

Studies have shown that blue light therapy can be an effective treatment for mild to moderate acne. It works by targeting Propionibacterium acnes (P. acnes), the bacteria that contributes significantly to acne breakouts. When blue light is applied to the skin, it's absorbed by the porphyrins within P. acnes bacteria, leading to the production of a form of reactive oxygen that effectively kills the bacteria.

In one study, a significant reduction in acne was observed in 77% of participants after eight weeks of treatment. Research has demonstrated that blue light therapy can be as effective as benzoyl peroxide, a commonly used acne medication.

These findings suggest that blue light therapy may offer a viable and potentially gentler alternative for individuals seeking to improve their skin's clarity and reduce acne breakouts.
