I think it does work for spot treatments but if you deal with multiple frequent breakouts you might want to consider a mask or panel

I've been using late therapy for a while and find it very effective. I wanted to use this little pen like device because I do suffer from melasma due to my skin tone the blue light has been very effective for my acne. Unfortunately I'm returning this product because it has a light buzz and vibration which I do not like and is unnecessary.
