Quadthera

Quadthera is a South Korean brand that develops advanced skincare devices using ultrasound for home use. Instead of manufacturing traditional creams and serums, Quadthera focuses on technology that complements your regular skincare routine. Several of the devices use different ultrasound frequencies to provide skincare focused on hydration, radiance, skin texture, and a firmer appearance.

Quadthera is suitable for those who want to take their skincare routine one step further and be able to choose treatment based on the skin’s needs. The models work in different ways and have different programs. Therefore, it is important to choose the right device and follow the instructions for that specific model.

What is Quadthera?

Quadthera is a Korean brand of skincare devices using ultrasound technology. The brand was developed by ECO DM LAB, a company in Cheongju, South Korea. The company works with technical beauty tools and makes it possible to use principles from professional ultrasound technology in your at-home skincare routine.

There are several devices in Quadthera’s range. Quadthera V1, Titan and Penta use ultrasound that switches between different frequencies. PearlShot instead uses focused ultrasound and special interchangeable cartridges for different treatment depths. Teenz is a smaller and simpler model with three frequencies. Quadthera is therefore not a single device, but a brand with several different skincare tools.

What is Quadthera known for?

Quadthera is primarily known for its skincare devices that combine several ultrasound frequencies. During use, the device switches between the frequencies to provide different types of cosmetic skincare. Lower frequencies are used, among other things, in programs for hydration and application of skincare products. Higher frequencies are mainly used for care closer to the skin’s surface, with a focus on skin texture, radiance, and a firmer appearance.

One of the brand’s special features is called Q Mode. It is a program in which several ultrasound frequencies are used in a specific order. In Quadthera Titan, the program switches between 1, 19, 3, and 10 MHz. The idea is to combine several types of skincare during the same treatment. Quadthera Penta builds further on the technology and also includes the 25 MHz frequency.

What makes Quadthera special is therefore how the devices combine frequencies, programs, and intensity levels. You can choose a program based on what you want to focus on, for example moisture, soothing care, radiance, skin texture, or a firmer appearance.

Benefits of Quadthera

Quadthera’s devices are developed to provide more possibilities in the regular skincare routine. Which functions you get depends on which model you choose.

• Multiple ultrasound frequencies: Depending on the model, three, four, or five frequencies are used for different types of cosmetic skincare.
• Programs for different needs: You can choose programs based on what you want to focus on in your skincare routine.
• For home use: The devices are made to be used as a complement to your regular skincare at home.
• Used together with skincare: Models that are moved across the skin usually require plenty of a water-based conductive gel or a skincare product approved for the device. The gel helps transfer the ultrasound and allows the device to glide evenly over the skin.
• Models for different experience levels: There are both simpler devices and more advanced models with more frequencies and programs.
• Focus on the skin’s needs: Different programs have been developed with a focus on, among other things, moisture, soothing care, radiance, skin texture, and a firmer appearance.

How Quadthera’s ultrasound technology works

Ultrasound with different frequencies

Ultrasound consists of vibrations with such a high frequency that humans cannot hear them. In Quadthera’s devices, the frequencies are measured in megahertz (MHz). Different frequencies produce different types of vibrations and are therefore used for different purposes. In general, lower frequencies reach deeper, while higher frequencies work closer to the skin’s surface.

Instead of using the same frequency throughout the treatment, several of Quadthera’s devices switch between different frequencies. Which frequencies are used depends on the model. V1 has 1, 3, 10, and 17 MHz. Titan has 1, 3, 10, and 19 MHz. Penta uses 1, 3, 10, 19, and 25 MHz.

What is Q Mode?

Q Mode is Quadthera’s special program in which several frequencies are used one after another. In Titan, the order is 1, 19, 3, and 10 MHz. In this way, several cosmetic areas of use are combined during the same session, instead of the device working with only one or two frequencies.

Q Mode is not a medical treatment. Quadthera’s devices are cosmetic skincare tools. Results may vary from person to person and are influenced, among other things, by which model you use, what your skin looks like to begin with, which skincare product you use, and how regularly you use the device.

Treatment head in titan and the right gel

Quadthera Titan and Penta have a treatment head made of titan. This provides an even contact surface against the skin and helps the ultrasound to be transferred. For the device to glide easily and maintain even contact with the skin, you usually need to use plenty of water-based conductive gel or a skincare product that explicitly works with the device.

Do not replace the conductive gel with an oil-based product unless the user manual states that it is fine to do so. Always follow the instructions for both the device and the product you use with it.

Well-known products from Quadthera

Quadthera V1

Quadthera V1 is one of the brand’s first models. It uses four ultrasound frequencies: 1, 3, 10, and 17 MHz. The device has programs focused on hydration, soothing care, the skin’s elasticity, and more comprehensive skincare. V1 is suitable for those who want a device with multiple functions and the ability to adapt use according to the skin’s needs.

Quadthera Titan

Quadthera Titan is a more advanced model with four frequencies: 1, 3, 10, and 19 MHz. It has a treatment head made of titan, five different programs, and adjustable intensity. The programs focus on application of skincare products, soothing care, a firmer appearance, and radiance. There is also Q Mode, which combines all four frequencies. Titan is developed for regular use together with a suitable water-based conductive product.

Quadthera Penta

Quadthera Penta uses five ultrasound frequencies: 1, 3, 10, 19, and 25 MHz. It is a further development of the technology in the other models. The additional 25 MHz frequency is used for care closer to the skin’s surface. Penta has a treatment head made of titan and is suitable for those who want a greater selection of frequencies and programs focused on, among other things, skin tone, radiance, skin texture, and a firmer appearance.

Quadthera PearlShot

Quadthera PearlShot works differently from V1, Titan and Penta. It uses focused ultrasound, also called HIFU, and special cartridges for different treatment depths. The cartridges are designed for different cosmetic goals, such as skin tone, fine lines, and a firmer appearance. Because the technology differs from the models that are moved across the skin, PearlShot must be used especially carefully according to its own user manual.

Quadthera Teenz

Quadthera Teenz is a smaller and lighter model with three frequencies: 1, 3, and 10 MHz. It has three programs focused on preparing the skin for makeup, soothing care, and reducing the visibility of pores. Thanks to its lower weight and simpler programs, Teenz may be a good option for those who want to start using Quadthera’s ultrasound technology.

Who is Quadthera suitable for?

Quadthera may be suitable for those who want to complement their skincare with a device and regularly focus on moisture, radiance, skin texture, or a firmer appearance. Which model suits you best depends on what you want to achieve, how accustomed you are to skincare devices, and how much you want to be able to customize frequencies, programs, and intensity.

• Dry and dehydrated skin: Programs focused on hydration may be of interest, especially together with a moisturizing gel that is compatible with the device.
• Skin lacking radiance: Models with special programs for radiance and skin tone may be suitable if you want to give the skin a more even and refreshed appearance.
• Mature skin: Programs focused on firmness, skin texture, and the visibility of fine lines may be a complement to your regular skincare.
• Sensitive skin: Be extra careful. Start with low intensity, short sessions, and longer breaks between treatments. Stop using the device if the skin becomes irritated or if you feel discomfort.
• Oily and combination skin: Choose a light, water-based conductive product that suits your skin type. Do not use the device on areas where the skin is inflamed or damaged.

Quadthera is not intended to diagnose or treat acne, rosacea, eczema, or other skin conditions. If you have a skin condition, are receiving treatment for your skin, or are unsure whether ultrasound is suitable for you, you should consult a doctor or skincare specialist before using the device.

How do you use Quadthera?

Exactly how you use the device depends on which model you have. For models that are moved across the skin, for example Quadthera Titan, the following steps usually apply:

1. Cleanse the skin. Wash away makeup, sunscreen, and dirt.
2. Apply gel. Use plenty of water-based, conductive gel or a skincare product that is compatible with the device.
3. Select a program. Turn on the device, choose the desired program, and start with the lowest suitable intensity.
4. Move the device over the skin. Move the treatment head slowly upward while maintaining even contact with the skin. Do not hold it still in the same spot for an extended period.
5. Start gently. For Titan, the official guidance recommends that new users start with about five minutes and then adjust use based on how the skin reacts.
6. Continue with your skincare. When you are finished, you can continue with the rest of your usual skincare routine.
7. Clean the device. Wipe the treatment head with a soft, slightly damp cloth. Never immerse the device in water.

How long and how often you should use the device varies between models. More advanced devices and models with focused ultrasound may have completely different instructions. Therefore, always follow the user manual for your specific device over general advice.

Important safety advice

Quadthera devices are intended for cosmetic skincare, not medical treatment. Safety rules may vary between models. In the official guidance for Titan, use is discouraged during pregnancy and breastfeeding, if you have electronic implants, or on skin with active infections, open wounds, or other damage.

Do not use the device directly on the eyes or eyelids. Also avoid the center of the neck, the spine, and other areas that the user manual says you should avoid. Remove jewelry from the area you are going to treat. Stop immediately if it hurts or feels clearly uncomfortable.

If you have recently had laser treatment, radiofrequency treatment, injection treatment, or any other professional aesthetic treatment, you should ask the clinic when it is safe to start using the device again. It is especially important to follow the correct instructions because PearlShot uses focused ultrasound, while several other Quadthera models use ultrasound that is not focused in the same way.

What sets Quadthera apart from other skincare devices?

Quadthera differs from many other skincare tools by using multi-frequency ultrasound. An LED mask uses light, a microcurrent device uses a weak electrical current, and a radiofrequency device uses a different type of energy. Quadthera instead works with sound vibrations and combines different frequencies in its programs.

That does not mean ultrasound is always better than other technologies. They work in different ways and suit different needs. Quadthera may be an interesting choice for those looking for a Korean skincare device with ultrasound, multiple programs, and the ability to combine the treatment with serums, masks, or gels that are compatible with the device.
