HOW TUA SPA WORKS
Tua Spa: Two Technologies
Tua Spa is the new advanced deep cleansing and anti-ageing system for the face and neck which combines two clinically proven technologies used by spa professionals.
Ultrasonic waves are sound waves that vibrate above 20,000 vibrations per second. Tua Spa emits sonic frequencies up to 26,000 vibrations per second!
These tiny but incredibly fast vibrations (elastic waves) generate alternating low pressure and high pressure waves in water which lead to a phenomenon called 'cavitation' (see cavitation below). Cavitation is frequently used in clinical aesthetic practice as a method of deep cleansing.
With Tua Spa, cavitation causes a gentle but effective deep cleansing action of the skin's pores, removing impurities via microscopic jets, suction and an anti-bacterial action. At the same time the ultrasonic waves perform an exfoliating action via gentle vibrational peeling.
Ultrasound is also an efficient form of massage due to the compression and expansion effect of the ultrasonic waves on the skin which enhances microcirculation and facilitates the absorption of cosmetic products such as serums and moisturisers.
Special low voltage electronic micro-currents pass through the Tua Spa modulator to the skin. These micro-currents alternate positive and negative impulses up to a maximum of 500 micro-Ampere which can be regulated in 3 intensity levels.
Tua Spa uses micro-current technology to boost the local circulation of the skin and stimulate the skin's own renewal processes thereby improving the tone and firmness of the skin as well as encouraging regeneration of the tissues. Tua Spa micro-current technology is the portable equivalent of professional spa and salon treatments.
The Phenomenon of Ultrasonic Cavitation
Tua Spa uses high intensity ultrasonic waves (known as elastic waves) that pass through water as a series of compressions and expansions of the water molecules.
These compressions and expansions cause alternating high and low pressure waves through the water which generate a phenomenon called 'cavitation': Microscopic vapour bubbles ('vacuum micro-bubbles') form within the water where pressure is low, then oscillate very fast and collapse under the pressure of the surrounding liquid forming a mist.
The micro-bubble formation produces a gentle suction effect that helps to remove dirt and impurities from the skin's surface and pores. When the bubbles collapse this creates microscopic pressure jets which gently hydro wash the skin's pores.
Because the process of bubble formation and collapse happens very quickly, it creates localised energy in the form of heat which has antibacterial benefits and can help with conditions such as acne.
