If a person has herpes, why they can't they use a fat freezer machine? I didn't see a reason why but it states not to?

However, if you have a current outbreak around the treatment area, you should wait until it is fully cleared up. Also, CoolSculpting is not recommended for those who have developed shingles from a herpes virus. First, talk to the physician who treats you for herpes to see if he or she has any recommendations, such as taking a round of prescription anti-viral medication prior to treatment. After that, you can consult with a CoolSculpting Technician to develop a plan of action. Further, be sure to share your medical history and your concerns about this matter with them.

There is no reason to refrain from CoolSculpting simply because you harbor the herpes virus. In the United States, up to 68% of people are infected with HSV-1, which causes cold sores.  If you are having an outbreak, and are hoping to treat your submental area with CoolMini, I would just recommend waiting until your skin has cleared. If prior outbreaks are near the treated area, a prescription anti-viral medication should be prescribed before your treatment to  prevent activation of the virus. 
CoolSculpting may be contraindicated in people who have developed shingles from the varicella-zoster virus, which is a type of Herpes.  The neuropathy experienced by Shingles sufferers may be re-activated by a CoolSculpting treatment.  It is important to have your CoolSculpting done by a board-certified dermatologist, so that pre-existing medical conditions can be identified and problems can be avoided. Please find a board-certified dermatologist who can evaluate you to find out if you are a candidate for this highly effective, noninvasive body-sculpting technique.

What type Herpes are you referring to and where are any lesions on your body?
This would need to be discussed with your provider.

I would not recommend having a treatment under the chin if you have active herpes going on, but I don't see how it would affect treatment in other parts of your body.

Herpes is not a contraindication for having Coolsculpting . Having a history of post herpetic neuralgia from a previous shingles infection is considered a relative contraindication. This means case by case basis must be factored into the decision making process as a treatment may exacerbate or cause relapse of the condition because the virus remains dormant in the nerve roots and cold temperatures can possibly cause the condition to manifest 

Thanks for your question regarding herpes and aesthetic treatments like CoolSculpting.  These procedures are not contraindicated unless there is a current outbreak.  However, preventative antiviral medications like valcyclovir or acyclovir should be used if the treatment is done in an area where there has previously been an outbreak or herpes infection.  It is important to have your provider review and discuss your medical history, as well as risks and benefits any time that you do an elective treatment.
