  • there are other devices that work with ultrasound or galvanic. what is the difference between REX-KARA?

    The REX-KARA SPI Beauty System uses three treatment methods recognized in beauty medicine, namely ultrasound, galvanic and photon technology, synchronously and therefore at the same time. 

    It is unique in the world. This is the only way to effectively infuse the highly active ingredients of the specially developed and ionized REX-KARA care products into the skin.

    Other devices usually only have one or two functions, which moreover often cannot be used simultaneously, but only one after the other

  • where does the new REX-KARA beauty system differ from its predecessor?

    The new DEEP THERAPY Beauty System works with an ultrasound frequency of 1,7 Mhz.

    The infrared treatment was made possible by the absolutely new photon technology / light therapy replaced.

  • can the different spi care programs be used individually?

    Yes, of course you can use the care programs at any time as needed.

    However, you should first carry out REX-KARA Cleansing (program 1) before treatment with REX-KARA Deep Therapy (program 2) in order to thoroughly clean the skin and pores and thus prepare them optimally for the introduction of the active ingredient.

  • i am so excited about facial cleansing. can I do it daily?

    Yes, of course you can also carry out REX-KARA Cleansing every day.

    The active ingredients contained in the REX-KARA Hydra Active Cleansing Gel are particularly kind to the skin and additionally provide the skin with the necessary moisture.

  • can I also treat myself with the individual spi programs longer than indicated?

    Yes, you can also use the individual SPI programs longer than we recommend, depending on the desired treatment success.

    However, please note the relevant information in the enclosed operating and treatment instructions.

  • why should the spi-titanium head remain on every skin area for at least 5-10 seconds or reach these 5-10 seconds with circular movements?

    Depending on the strength and nature of the skin, the ultrasound waves and the ions need a certain amount of time to penetrate deep enough into the skin tissue.

    Likewise, the pollutants and impurities in the skin need a certain amount of time to reach the surface of the skin and the active ingredients in turn have enough time to penetrate deeply into the skin.

    By adhering to the specified duration of treatment, the efficiency of these processes is to be guaranteed.

  • what is ionized cosmetics?

    Ionized cosmetics were electrically charged using special manufacturing processes. This is the prerequisite for the highly active ingredients to be transported into the skin using galvanic.

    This so-called iontophoresis is also used very successfully in medical therapy, for example to inject certain medications into the body through the skin.

  • I have an older device that only works with galvanic. can I use the REX-KARA care products with it?

    Yes, you can basically use all REX-KARA care products with any other device that works with galvanic, ultrasound or photons, as they have been specially developed and ionized for this.

    The REX-KARA Hydra Active Cleansing Gel is positively ionized, while all other REX-KARA gels and serums are negatively ionized. You must therefore set the same polarity on your device that the respective REX-KARA care product has.

  • i feel the treatment sometimes stronger and sometimes less strong. is that normal?

    Yes, that's normal.

    The sensitivity of the skin varies depending on various circumstances, such as the time of day, general condition, the degree of moisture in the skin, the pH value on the surface of the skin, etc.

    If you ever feel that you don't feel anything at all, this may also be due to the fact that your palms are too dry and therefore the galvanic fine current cannot flow through the body optimally via the contact strips on the handle. In this case, simply moisten the palm of your hand a little.

  • why does the device switch itself off after a while?

    The automatic switch-off of the device enables you to precisely control the duration of the treatment without having to keep an eye on the watch.

    If you want to continue the treatment, simply switch the device on again and carry out the corresponding steps as before.

  • How long can I stay on a skin area with the treatment head?

    We generally recommend that you leave the treatment head on each skin area for at least 5-10 seconds so that the processes in the skin can run optimally.

    Of course, you can also treat wrinkles, love handles etc. more intensively as required. Please note, however, that you should never remain on the same area of skin for longer than 20-30 seconds.

  • I sometimes get pimples after cleaning my skin. can't I tolerate the cleaning gel?

    It is quite normal that during the first treatments with REX-KARA Cleansing (program 1) or even after a long break in treatment, more pimples can appear, since the skin is cleaned from the inside and pollutants and impurities are transported to the skin surface.

    As a rule, these pimples evaporate after only a few applications if the skin is clean to the pores. If necessary, you can speed up this process somewhat by using the REX-KARA Pure Balance Correcting Serum with REX-KARA Deep Therapy (program 2).

  • can I continue to use my existing cosmetics for normal facial care?

    Of course, you can apply your normal day and night care as usual after the treatment with REX-KARA

  • I have terrible pimples and blackheads. can I still use REX-KARA?

    Yes, the REX-KARA SPI Beauty System is even ideal for treating pimples and blackheads.

    We recommend doing REX-KARA Hydra Active Cleansing Gel after REX-KARA Cleansing (Program 1) with REX-KARA Deep Therapy (Program 2) and REX-KARA Pure Balance Deep Correcting Serum.

    For particularly sensitive and irritated skin, you should first carry out the treatment with the REX-KARA Photon Face Therapy (program 5) and the REX-KARA Pure Balance Correcting Serum until the condition of your skin has normalized.

  • I have used REX-KARA youth spectacular and hyaluron boost without infiltrating it, and I am thrilled with the feeling on the skin. can I use the REX-KARA care products without a device?

    Of course, you can use all REX-KARA care products as normal, even without using ultrasound or galvanic, since they generally contain combinations of active ingredients that care for the skin.

    However, you have to cut back on the specific effectiveness, because the active ingredients cannot get into the deeper layers of the skin.

  • do I have to remove make-up before using the spi?

    Yes, please remove any make-up before the treatment.

  • can I also remove make-up from you with the cleansing gel?

    No, the REX-KARA Hydra Active Cleansing Gel was specially developed for deeply effective skin cleaning with ultrasound and galvanic and is generally not suitable for removing make-up.

  • can i start the treatments with the highest intensity?

    You can basically start the treatment at any intensity level and change it as often as you like depending on the sensitivity of the skin during the program.

    We recommend starting treatment at the highest intensity level and gradually reducing it if necessary.

  • can i also use other cosmetics for treatment with REX-KARA?

    In principle yes.

    However, it usually makes little sense since conventional cosmetic products are not ionized and therefore cannot be infiltrated into the skin using iontophoresis.

    Even if the products of other suppliers are ionized, we do not recommend use. They could possibly contain harmful substances that should under no circumstances be introduced into the skin.

    The REX-KARA care products have been specially developed for use with ultrasound and galvanic and are correspondingly ionized. In addition, all products have been dermatologically tested and skin tolerance has been confirmed. In addition, all products are guaranteed free of PEGs, silicones, parabens, mineral oils and dyes.

  • can i treat other people with the spi?

    Of course, you can also treat another person - but please make sure that there is direct skin contact between you.

    For example, you can easily touch your bare arm or shoulder with your hand. Through direct skin contact, you close the fine circuit and activate the galvanic ionization, which is responsible for the active ingredient injection.

  • i don't feel anything during the treatment. can it be that my spi is not working properly?

    Depending on various factors, you may feel the treatment more or less strongly or sometimes not at all. This is quite normal and is by no means an indication that the SPI is not working properly. Among other things, the SPI works with ultrasound, which you can neither feel nor see nor smell. If you want to make the ultrasound visible, please follow the steps below:


    •  Choose a program that uses ultrasound (1, 2, 3, or 4)
    • Adjust the ultrasound impulses using the intensity button
    • Put a drop or two of water on the SPI titanium head
    • Be sure to hold the SPI at the contact points

    The result: the vibration becomes visible. The drop is moving

  • what is the difference between the programs and the treatments?

    The individual REX-KARA SPI programs are set differently, they use different technologies and therefore also achieve differentiated results.

    In addition to using the individual programs, you can also use your SPI for more extensive treatments.

    The properties of the five programs are optimally combined in the 18 treatments.

    This is like a treatment in a beauty salon, which consists of different steps and products, which are selected with regard to the nature of your skin and in which the length also varies as required.

    For example, the “Cleavage Lifting” treatment combines the Deep Therapy and Classic Therapy programs and, depending on the skin type, recommends the use of REX-KARA Youth Spectacular or Pure Balance. You can also choose between "Daily" and "Intense" and thus determine the duration of the treatment yourself.

  • what exactly does the ultrasound do?

    The titanium head generates ultrasound waves with 2 million vibrations per second, which penetrate to the bottom layers of the skin and alternately exert pressure and suction on the tissue.

    The mechanical effect loosens the skin tissue, increases the cell spacing and loosens stuck slags. This enables the skin to better absorb cosmetic ingredients such as creams and serums.

    The thermal effect of ultrasound also accelerates blood and lymph circulation, increases oxygen supply, stimulates cell metabolism, strengthens connective tissue and stimulates the natural production of collagen and elastin as well as the burning of body fat.

  • what exactly does galvanic do?

    The titanium head creates electrical potentials that cause micro currents to flow when the skin is touched. The microcurrents drag charged particles (ions) with them and transport them through the skin surface.

    During cleaning, the microcurrent flows out of the skin to the titanium head and carries pollutants from the deeper layers of the skin and impurities from the pores to the surface of the skin. During the drug injection with the SPI, the microcurrent flows through the titanium head and supplies the skin with ionized cosmetic agents.

    In this way, the skin undergoes thorough deep cleansing and a highly efficient supply of active ingredients that cannot be achieved with conventional methods. In addition, cell regeneration and the body's own structure of collagen and elastin are promoted.

    The skin is regenerated from the inside by the application with the SPI and receives elasticity and elasticity. Wrinkles are visibly reduced and the skin appears smooth and supple.

  • what exactly does photon technology do?

    The lamps on the SPI titanium head generate colored light.

    The energy of the blue light has an antiseptic effect and is used to clean the skin and to relieve inflammation and skin irritation.

    Whereas the energy of the red light increases the blood and lymph circulation, activates the natural self-production of collagen, elastin and laminin and is used in particular for drug delivery.

  • I have very sensitive skin and am prone to allergies. can I still treat myself with the spi and the ionized care products?

    Yes, but please note the information in the operating and treatment instructions. Basically, all products have been dermatologically tested and skin tolerance has been confirmed.

    In addition, all ionized products are guaranteed to be free of PEGs, silicones, parabens, mineral oils and dyes. All REX-KARA care products contain high-quality ingredients and, not least thanks to the use of an anti-allergenic perfume, are well tolerated even by sensitive skin. Hyaluron Boost even completely dispenses with perfume and preservatives.

  • when should you completely forego treatments with the spi?

    When using a pacemaker and during pregnancy, you should generally not use the SPI.

  • How can I tell that the device's battery is fully charged?

    The red charging lamp on the handle flashes during the charging process.

    When the battery is fully charged, the lamp lights up red.

  • there are various devices on the market that use different mhz frequencies. what is the mhz frequency at REX-KARA?

    The SPI uses 1,7 MHz frequencies in order to be able to optimally develop its effects in combination with the ionized REX-KARA care products.
