How Do Exilis Treatments Actually Help Reduce the Fat?

Exploring Exilis for skin tightening & fat reduction, and am trying to fully understand how it works. What actually happens to the fat cells during the Exilis treatments? I've read they "shrink", but if that's true, how is that different than what happens after regular, consistent exercise?

Also, if radio frequency waves surpass the outside layer of skin and penetrate into the dermis, how does that then make the skin/area look tighter? Can "destroying cells" really be good? Analogies? Help!

Exilis is a FDA approved form of skin tightening and also does fat/volume reduction.  Exilis is a radio-frequency device that puts a lot of energy into the skin.  This energy bulk heats the skin causing the collagen to tighten and causes the fat cells to open and spill out the contents. 

It is an effective way to spot treat exercise resistant fat - think stubborn lower abdomen pooches or love handles.   No cells are officially "destroyed". 

Good Luck!

Exilis Treatments Heat the Skin to Remove Fat and Tighten the Skin

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Exilis treatments use radiofrequency which is a type of energy that produces heat.  Exilis treatments utilize an applicator that is massaged over the desired treatment area.  This applicator cools the top of the skin while pushing the the heat to the fat layer.  The heated fat cells become metabolically active which causes the fat to exit the cell.  Once the fat exits the cell, it is excreted.  Post-treatment exercise and hydration will promote the elimination of the fat.

The treated fat cells are injured during the process and become unable to uptake more fat.  Many of the fat cells do not recover and this eliminates these cells as a fat storage site.

After the fat melting, the cooling on the applicator is turned off which allows the focus of heat on the top layer of the skin thus producing skin tightening.

Exilis Ultra is an outstanding treatment for skin tightening that combines two of the best technologies available for this purpose: radiofrequency (as found in Thermage) and ultrasound (as featured in Ultherapy). That means you get the best of both worlds!

Those two forms of energy heat up the collagen in the skin causing it to contract leading to skin tightening in the treated area. They also stimulate collagen production which will lead to further tightening visible within 4-6 months so you get an immediate and long-term benefit. The most common areas I treat are the eyelids, lower face (for the jowls), neck, and abdomen but any body part can be treated, including private areas. It also works well for cellulite especially when combines with our Cellutone treatment. 

The same combination of radiofrequency and ultrasound also works on fat cells by destroying them. The fat stored within leaks out and is excreted by your body. In this sense, the results are permanent as long as you don't gain a lot of weight. This also is perfectly safe without any short or long term side effects.

The treatment feels like a hot stone massage and is usually performed every other week for a total of four treatments. There is zero downtime and you can return to your regular activities immediately. There are no short term side effects other than the sensation of heat and there are no long term side effects other than tightening of the skin! No aftercare is necessary though I do recommend a combination of skin care products to further boost and support collagen production. There results aren't permanent; we are simply turning back the clock but the clock will keep ticking. After your series of four, I recommend maintenance treatments once or twice a year depending on your age, genetics, starting point, and lifestyle considerations.

Exillis heats the fat cells, they burst , which then results in cell death.  This is called apoptosis. The radiofrquency heat targets the fat cells themselves and does not burn the surface of the skin.
