How it works

See what Tesla 21 can do

Function 01

Pelvic floor

Tesla 21 stimulates the pelvic floor muscles in depth. These muscles help support the pelvic organs and control urination, and the treatment is done while the client stays fully dressed.

Contractions The technology produces 20,000 muscle contractions in 30 minutes.
Support The stimulation targets the pelvic floor muscles that support the pelvic organs.
Role A well-functioning pelvic floor also plays an important role in sexual function, including arousal and orgasm.
Format The client stays fully dressed on the chair, with no gel and no need to undress.
Function 02

Rehabilitation

The stimulation can also be included in recovery programs for muscles weakened after illness or injury, without mechanical load on the joints.

Combination The technology combines nerve and muscle stimulation for more intense activation of the area.
Circulation The stimulation supports local blood circulation and tissue nutrition.
Metabolism The rhythmic contractions stimulate metabolic processes in the treated area.
Applications According to the specification, the system is also used for certain neuromuscular conditions involving limited movement and muscle hypotrophy.
Function 03

Muscle volume and density

Repeated contraction and relaxation help build muscle fibers and make them denser.

Hyperplasia The stimulation helps increase muscle density and tone.
Depth The field reaches up to 10 cm deep and activates the muscles without voluntary effort.
Intensity The technology produces stronger contractions than those normally achieved voluntarily.
Result In 30 minutes the technology produces 20,000 muscle contractions.

Always known for her elegant and dignified presence, Diana chose to preserve her beauty and youth with HIFU treatments, because it is a non-invasive therapeutic technology that helps awaken the body's own resources, leaving her fully satisfied with the result.

Her music has been performed and released in 25 countries on 4 continents, and her lyrics span 17 languages. Her song “Aadiya” was selected by NASA for transmission into space aboard the Space Shuttle Columbia. Diana Dafova also holds the prestigious Gold Remi Award for her concert in Las Vegas.

“HIFU is a proven, modern non-invasive technique based on ultrasound waves, used for non-surgical face and body lifting with great results visible after the very first treatment.

Ultrasound has been used for diagnosis in medicine for many years, and in recent years it has made great progress as a therapeutic treatment in aesthetic medicine. The only side effects shown by clinical studies so far are short-lived swelling and redness of the treated area, and not in all patients. I recommend this method because, first and foremost, it is harmless, and its effect is immediate.”

I highly recommend it. Here in Dubai, women know which technology to choose to look their best!

I had the great honor and pleasure of trying HIFU by Denny Divine treatments for beauty, rejuvenation and other health benefits. A wonderful experience and clear changes for the better, thanks to the reliability and professionalism that Denica Voynova embodies.

One of the results is instant and almost unbelievable. You see your face before and after treatment with this wonderful technology, at the highest and most modern level. People my age, over 55, are very happy with the change, which is clearly visible after the treatment.

Denica is a miracle worker in every respect when it comes to energy and technology. Huge thanks from me to Denica, the program and the HIFU by Denny Divine team. Body and soul enjoy this treatment!

I have known Denica since she was a little girl. I truly value her professionalism and knowledge, her passion, ambition and personality! When I wanted my first real facial care, I went to her because I trusted her.

After two HIFU facial treatments, my face and skin felt much fresher and firmer within just a few days, the fine lines disappeared and my skin looked renewed. It is not a miracle cure and it will not iron out every line, but it leaves the skin lively, soft, radiant and fresh.

I would definitely repeat the HIFU treatment, and only with Denny, because I trust her and I am very happy with the results so far!

I want to thank Denny for her great professionalism and the attention she gives me, and to express my sincere admiration for the incredible result of the rejuvenating treatment with HIFU by Denny Divine.

I felt a difference right after the first session: my skin became firmer, radiant and refreshed. The treatment was completely painless and comfortable, and the modern equipment saves you the cost of expensive surgery with the same effect.

Every step was explained in detail, and the care I received made me come back again and again. I highly recommend it to anyone who wants to keep their skin healthy, young and beautiful!

“I was extremely happy with the HIFU by Denny Divine treatment. Right after the first session my skin looked firmer and fresher, and the results after Foxy eyes are impressive.

My eyelid is lifted, my brows are raised and my eye looks more open. The treatment was comfortable. I saw a big improvement in my facial contour and an overall rejuvenated look, exactly what I was looking for, and I found it here! I will definitely be back for more treatments!”

Doing business with Denny is very simple, fair and professional. We work with Denny easily, with great mutual trust and respect, as partners in selling and distributing HIFU equipment.

Her well-developed business model and training encouraged us to buy the best device on offer, the HIFU Ultraformer 7D, and to open a HIFU center in Croatia. The results we have achieved are of exceptional quality, and our clients are very happy.

Denica Voynova is a very fair business partner, always ready to help, full of great ideas and with excellent knowledge of working with HIFU devices.

“For years I have had the chance to work with HIFU equipment and watch its results, and I can confidently say they are impressive and apply to absolutely every area of the body and face.

I have worked with my own device for 2 years, and the results are impressive and lasting. That keeps my clients coming back and recommending my services to their family and friends. Denica Voynova has established herself in the market as a fair and reliable partner you can count on.”

Mariana Nikolova, Mani
Mariana Nikolova, Mani Manual therapist, HIFU 7D

“I have worked in a beauty salon as a manual therapist for more than 20 years, but in 2024 I bought a HIFU 7D device for non-surgical SMAS lifting.

Fate brought me together with Denica Voynova at just the right time, so I could discover this magical device, which first transformed me and my own body in an amazing way. In 9 months we achieved unique results: visibly firmer and smoother skin, and quite a few centimeters lost from places that are hard to reach with manual techniques. At almost 55, I have not had skin this beautiful and smooth since I was young.

Denny Divine is a brand we work with successfully in beauty and aesthetics. I am happy to have the honor of working with partners who value beauty, good intentions and results.”

The results after HIFU are incredible. You can see them even after the first treatment.

I bought the device from Denica Voynova and she gave me great training. Denny is fair and an excellent professional in her field, and I am in the process of buying more equipment from her.

My Denny, you are the best teacher I have ever had in my life. Despite the language barriers, you are always there and always explain everything to me.

I am grateful and happy to have you and to learn from you.

“I am extremely happy with the results of my new equipment from Denny Voynova. With the 5D HIFU I get incredible results in face, neck and décolleté lifting, as well as in melting fat and tightening loose skin on the body.

My clients are happy and send me new clients, which speaks well of my work and of the equipment. And with the Estella laser I have rounded out my services, because it lets me remove old pigment from brows or eyeliner and do new micropigmentation.

In short: I do not regret this investment, because it helps me grow and be useful to my clients and to myself. Thank you, Denny.”
