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

The MENDS of Halo

The 'mends' of Halo are expected and indicate you are getting a great response to the treatment.  Mends stands for 'microscopic epithelial necrotic debris' and are the result of the 1470 laser energy creating these columns of injury that are absorbed into the deeper tissue or come to the surface.  Your skin will look and feel like sandpaper for up to a week as these come up and flake off with the healing process.

MENDS are a predictable part of healing from a laser resurfacing treatment.

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.

Mends is Normal

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.

"Mends" = great response to Halo Treatment

The 'mends' of Halo are expected, you are getting a great response to the treatment.  Mends stands for 'microscopic epithelial necrotic debris’, which is a result of the ablative portion of the laser creating these columns that are absorbed   into the dermis that come to the surface.  Your skin will look and feel like sandpaper for 5-7 days.  Gentle washing of the face ( no picking or scrubbing), followed by Cicalfate cream  9 used in our office helps heal the skin. We also schedule a follow up at 1 month to check progress.

Hope you found this answer helpful.  All the best!

MENDS post Halo

Based on your description, you are healing as you should, and MENDS is usually an excellent sign 3 days post Halo treatment. Consult with your treating physician as he or she knows the scope of the treatment and the specifics about you.

MENDS are Great

You want this!  Once they appear, your job is to be gentle to your skin, protect it, follow your provider's instructions and let the MENDs go away on their own schedule.  Go, MENDs!

Halo Healing

This is a normal and expected part of the healing process.  It sounds like you responded well to treatment.  Your skin will have a rough texture during this phase, but after 5-7 days the majority of the "MENDs" should shed.  Good luck and enjoy your results!!

It is very common to develop darker colored small spots all over the face around 2-3 days after HALO laser treatment. These are the MENDs that you mention.  These will go away over time.  In my patients that MENDs have typically disappeared at 5-7 days depending on how aggressive the treatment was that they received.  Your skin will feel very dry and rough which is normal.  As you shed the MENDs this should reveal new healthy soft skin underneath.  Make sure to use sunscreen with an SPF30 or greater after your treatment.  In patients with darker skin, which may include yourself, this cannot be emphasized enough to prevent hyperpigmentation after laser treatments.  In some cases I recommend pre- and post-treatment regimens with hydroquinone to further decrease the risk of hyperpigmentation in people with darker skin.

Take care,

MENDs after HALO

If you are talking about the small raised coffee brown spots all over your face then that is a normal process of healing after HALO. Within a week, the spots will fall off. Your face will feel like sand paper but you will start to peel and your face will feel smooth again. Make sure you use a good physical block that contains titanium and zinc.  However, if you are experiencing hyperpigmentation than you should visit your doctor.

Halo laser and pigmentation issues for Asian patients

MENDs?   Microscopic Epidermal Necrotic Debris? 

I assume that you are asking about the texture change and temporary color change associated with the fractional aspect of Halo laser treatment. 

After Halo, our patients are generally on a very strict protocol of sun avoidance and an array of topical products used to facilitate the healing process and to prevent hyperpigmentation. 

Would suggest calling your physician.
