I get a lot of questions about rosacea treatment at medical spas or by estheticians. Very few are geared towards dealing with rosacea and many times just keep 'angry face syndrome' going in a vicious cycle.
I want to thank Ruth Padilla for forwarding me this interesting excerpt about a potential esthetic treatment and/or take home treatment device.
We use ultrasound all the time in medicine and biomedical research, so I am quite familiar with what it does, how it does it and why it might help. Below is a very good article that holds up to scientific rigor based on the theories. Very interesting to see how this progresses.

Advance Ultrasound Treatment for Skin
The frequency resonance hypothesis aspires to increase healthy skin cells with the treatment of non-thermal levels of ultrasound. With more than four decades of research and recent findings describing the effects of non-thermal therapeutic levels of ultrasound at the cellular and molecular levels, skin care specialists are beginning to consider incorporating this advanced mechanical modality tool for results-oriented skin treatments.
What is ultrasound?
Ultrasound, a cutting-edge technology, utilizes low-frequency sound waves in a three-stage system for safe mechanical exfoliation, molecular penetration and healing micro-amp therapy to combat aging skin, reduce wrinkles, clear acne, manage rosacea and control hyperpigmentation, in addition to many other skin challenges.
Skin types and skin tones of all types benefit from ultrasound. In fact, clinical studies have established that ultrasound can increase the efficacy of certain skin treatments by as much as 10,000 times. The most obvious extrinsic changes can be seen with acne grades, rosacea and Glogau 3- and 4-aged skins that exhibit the most obvious visual clinical morbidity. The rapid response time for skin will vary due to genetics. However, because ultrasound has the ability to support cellular repair, increase collagen and elastin, hydrate the skin and kill bacteria and viruses, dramatic results are seen and felt even after the first treatment.
The frequency resonance hypothesis provides two possible biological mechanisms that may alter protein function as a result of this absorption. Absorption of mechanical energy by a protein may produce a transient conformational shift that modifies the three-dimensional structure and alters the protein’s functional activity. The resonance or shearing properties of the sonic wave may dissociate a multi-molecular complex, thereby disrupting its function. In addition to removing the damaged micro-thin cell layers of the epidermis, the cavitation stimulates lymph nodes that, in turn, assist in detoxifying connective tissue to promote healthy skin.
Aging skin, acne, rosacea and hyperpigmentation are linked to inflammation. Medical research data provides examples in which exposure of cells to therapeutic ultrasound under non-thermal conditions modified cellular functions. Non-thermal levels of ultrasound modulate the cell membrane, alter cellular proliferation and increase production in proteins associated with inflammation and injury repair. The data suggests that non-thermal effects of therapeutic ultrasound can modify the inflammatory response, thus providing a friendlier environment for cells to reside.
The second phase of ultrasound treatments initiates sonophoresis that uses ultrasonic frequencies to help transfer substances of high molecular weight throughout the skin. Low-frequency ultrasound just above the range that is audible to the human ear enables dissolved gases in liquid regions between skin cells to bubble and move, clearing toxins caused by free radical activity. The sonophoretic action creates pathways into the skin, allowing specific molecules to enter. Using low-frequency ultrasound—sound waves oscillating at a rate above 20 kilohertz—is essential.
Obtaining healthy skin can be achieved only with healthy cells. Working inside out, therapeutic ultrasound produces a combination of non-thermal effects, such as acoustic streaming and cavitation, which are difficult to isolate in other ways. Acoustic streaming results from the physical force of sound waves that are capable of displacing ions and small molecules. The mechanical pressure produces unidirectional movement of fluid along and around cell membranes.
Ultrasound treatments provide a safe, effective treatment for skin tones that are color blind to all ethnic blends. This mechanical method exacts results by increasing the bioavailability of antioxidants, providing spas with a substantial advancement for treating skin of color. The procedure kills bacteria and viruses, but, unlike with microdermabrasion, there is little pain, inflammation or irritation.
A skin care tool that can be utilized in the treatment of all skin types and conditions is a valuable resource in the esthetic environment. Introducing ultrasound for use in medical spas, skin clinics, skin care centers, destination and treatment can improve treatments and programs. As science continues to progress and reveal more ways to fight aging, acne and hyperpigmentation, one thing is certain—ultrasound is here to stay.
