Which one is the best for an acne treatment: e-light or nd yag laser?

Blue light and photo: If you are trying to reduce the frequency of braekouts then blue light and a photosensitizer such as levulinic acid is really quite good with up to 1 yr reduction in break outs. However if you are trying to resurface the effects of acne, ie fatten the mountains and raise the valleys really er yag is a good modality but the skin much be pretreated if fitz iii and above to prevent hyper-pigmentation.

Acne laser treatment: There are several lasers to treat acne and acne scars. Much of the data is comparable. My advise would be to seek a board- certified dermatologist who is knowledgeable in lasers and consult with them to to see which laser would be most beneficial for you.
