Three days ago, I had the Halo laser procedure. I am Asian and now have developed tons of MENDs. Will these disappear?

Hi EmmaLothlorien, thanks for your question.
This is great news. MENDs are “microscopic epithelial necrotic debris.” They appear as a predictable part of healing from a laser resurfacing treatment such as Halo. The Halo laser creates intentional, microscopic columns of injury in the skin. In the days following treatment, these microscopic columns are shed from the skin as MENDs. In this phase of healing, the skin typically takes on a dry, “sandpaper-like” quality before revealing the new, smoother skin below. 
While not all patients develop significant MENDs, this is often an indication of a good response to the treatment. Continue to follow your post-care instructions and look forward to following up with your doctor to review your results.  

The more MENDs you see, the more aggressive a treatment and/or response you'll probably get. Seen lots of them makes me happy. You sti need to be carful to fallow your post procedure instruction to guarantee a great results. MENDs should start to fall in the next few day. If you feel this is not happening, I would recommend to see your provider for an evaluation. Best, Dr. RG

Firstly, congratulations to you, because having the mends means you're on your way to a great results. the appearance of the mends is an expected outcome of this procedure, because it forces the pigmentation to come to the surface through the fractionated openings, and we usually expect this process to be completed by day 5, especially if you have had a lot of pigmentation and sun damage in your history. The next stage of your healing is going to be that you absolutely protect your skin against the sun with the right sunscreen that is SPF 30 with protection against UVA and UVB light. Please make sure you follow up with your physician within the first week of your treatment to make sure you are reaching the right milestones of your recovery.
