Will drinking Alcohol after my Halo Fractional Laser Treatment affect the healing process?

You know the answer! Alcohol will not delay healing, it will just diminish results in the sense that your skin will be dehydrated and dehydrated skin looks dull and saggy.  But in the short term, there would be no healing problems. 

Drinking alcohol after having a Halo treatment shouldn't affect the results after your treatment. As alcohol is dehydrating to the body, it may slow down the healing process or the patient may feel dryer during the time of flaking. It's best to double up on your water intake and use as maybe hydrating lotions if possible.

Alcohol after laser treatments may make the redness worse and could dry out your skin.  Only more than moderate alcohol or chronic alcoholism will slow the healing process.
I usually allow 1-2 glasses of wine the night of the Halo laser treatment if they desire.Ken Oleszek, MDLa Fontaine AestheticsDenver, CO
