What Is the Difference Between ThermiSmooth and ThermiTight?

As the demand for anti-aging solutions continues to surge, consumers are looking for new, less invasive options to turn back the clock. Cutting-edge options like ThermiSmooth and ThermiTight that address issues such as skin laxity and wrinkles have therefore become very popular. Let’s find out what is the difference between ThermiSmooth and ThermiTight.


ThermiSmooth and ThermiTight are two of the anti-aging procedures available on the ThermiRF platform developed by Thermi Aesthetics. ThermiRF is a multi-application system that utilizes radiofrequency (RF) energy to combat signs of age. It combines wrinkle reduction and skin tightening technologies, to create an effective skin rejuvenation treatment.

ThermiRF system is FDA approved for use in cosmetic enhancement procedures. The system is safe and comfortable, and produces very impressive results. The ‘science of heat’ is what makes ThermiRF so effective, as the technology precisely heats soft tissue, ensuring that you get the results you want. ThermiRF is suitable for all skin types.


ThermiSmooth is a skin rejuvenation procedure that makes your skin smoother and tighter without downtime. The heating action revives the skin cells, creating a more youthful appearance. ThermiSmooth is commonly used to smooth fine lines and wrinkles around the eyes, and also to help with reduce cellulite.

How it works

The controlled RF energy gradually heats the deep layers of the skin, where it stimulates collagen and improves the quality of the skin. The additional collagen provides the structural support the skin needs to become stronger and firmer.

The handpiece is moved across the treatment area in a circular motion, and the temperature can be adjusted depending on the specific area being treated.

For optimal results, doctors usually recommend 4-6 treatments with ThermiSmooth, spaced about 2 weeks apart. Treatment time is 10-30 minutes on average, depending on the size of the area being treated. Clients can resume regular activities immediately afterwards.

What Results can you Expect

Patients often notice a softening of wrinkles after the first treatment, but it will take a series of treatments to get the desired aesthetic result. Final results can take 3-6 months to show.


If you are not yet ready for a surgical facelift and neck lift, ThermiTight may be the right procedure to tighten those loose areas. ThermiTight corrects mild to moderate sagging, and is especially beneficial for tightening the skin in the lower face, jowls, and neck. It is the ideal solution for individuals who want to achieve tighter skin without surgery.

How it works

ThermiTight tightens the skin by way of a tiny thermistor probe that is inserted through tiny incisions made in the treatment area. The probe heats the subdermal (inner layer) tissues below the skin, to a user-selected temperature.

During the procedure the system computer monitors and regulates internal temperatures, in order to ensure that the procedure is safe and there are no burns. If the temperature is getting too high, the device will turn off automatically.

ThermiTight is an in-office procedure that is done using local anesthesia. It only takes a single treatment of 20 minutes duration, to produce remarkable skin tightening results.

The protocol provides excellent results for individuals with mild skin laxity.

What results can you expect

You can expect to see some immediate results after the treatment session, but the skin will continue to contract for the next few months.

What is the Difference between ThermiSmooth and ThermiTight?

ThermiSmooth is designed to smooth fine lines and wrinkles, particularly those around the eyes and mouth. Treatment is done using an external handpiece on the surface of the skin.

ThermiTight uses a probe that is inserted beneath the skin, and is therefore a more aggressive treatment. It is designed to tighten the skin, and can also help to reduce fat deposits. It is very effective when used to tighten the jowls and neck.

ThermiTight is more effective for treating excess skin, while ThermiSmooth is more suited for reducing the appearance of lines and wrinkles. These procedures are both suitable for people who don’t want to undergo surgical facial rejuvenation procedures.
