Blue light therapy at 415nm kills acne-causing bacteria without medication. Here are the top FDA-cleared masks that actually work.
Blue LED light at 415nm penetrates sebaceous follicles and activates porphyrins inside acne bacteria (P. acnes), destroying them from within. It also reduces inflammation and regulates sebum production. Red light (630nm) added alongside blue light reduces healing time and calms post-acne redness. The combination of blue + red is more effective than either alone.


CurrentBody Series 2 and Omnilux Contour Face do not include blue light — they use only red and near-infrared wavelengths, making them excellent for anti-aging but not suitable as primary acne treatments. If acne is your main concern, the Dr. Dennis Gross or iRestore Illumina are the clear choices. If you want to treat both aging and acne simultaneously, the iRestore Illumina is your best single-device solution.
