Modern self-care gadgets are no longer just a fashion accessory and have become effective tools for cosmetology, available to everyone. Xiaomi’s ultrasonic scrubber, often released under the InFace sub-brand, is one of the most popular devices in this segment due to a combination of affordable price and proven effectiveness. Many users buy a device hoping to instantly get rid of black dots and improve skin tone, but without understanding the principles of ultrasound, the result can be zero or even negative.
The basic principle of action is cavitation, which is the process of forming and collapsing microscopic bubbles in an aquatic environment under the influence of high-frequency vibrations. Water is a critical conductor of ultrasonic waves in this context. If you start the procedure on dry skin, not only will you not get the cleansing effect, but also risk damaging the epidermis due to excessive friction and lack of the necessary acoustic environment. Without a copious amount of fluid (tonic, micellary water or special gel), ultrasound does not work.
In this article, we will discuss in detail the skin preparation algorithm, the procedure technique for different types of contaminants and the nuances of caring for the device after use. Proper operation will extend the life of the shoulder blade and get a salon result at home. Let's look at how to turn this compact device into your personal beautician.
Skin Preparation: The Foundation for Effective Cleaning
The quality of ultrasonic cleaning is 80% dependent on how well you prepared your face before coming into contact with the shoulder blade. Steaming is not just a recommendation, it is a prerequisite for expanding the pores and softening the sebaceous plugs. You can use traditional steaming over warm water with herbs or use modern hydrator gels that do not require heating and are suitable for sensitive skin with couperosis.
Once the pores have opened, you need to apply the treatment agent to your face, ideally suited hydrophilic oil, special ultrasonic cleaning lotion or just a copious amount of toner, it is important that the skin remains moist throughout the process, if the liquid is quickly absorbed or evaporated, hydration should be resumed with a spray gun.
Do not attempt to clean the skin with residues of decorative cosmetics or skin fat. Pre-washing with a soft foaming agent will remove surface contaminants, allowing the ultrasonic wave to work directly with the contents of the pores. Ignoring this step will lead to rapid contamination of the shoulder blade and reduce the effectiveness of cavitation.

Overview of operating modes and functionality of the device
Most Xiaomi ultrasonic cleaning models, including the InFace Sonic Scrubber, have multiple modes of operation, each of which solves problems. Understanding the difference between them is necessary for proper care. Usually, the switching of modes is carried out with a short press on the power button, and the indication of the current state is displayed by an LED or a text display.
The first mode is the direct ultrasonic cleaning (Cleaning), in which the shoulder blade vibrates at a high frequency (usually around the same time). 24 000 – 30 000 Hz, knocking out contaminants from the pores The second regimen is often labeled as "Nutrition" or "Introduction" (Nourishing/Import). Here, the frequency of the oscillations changes, which helps the serum and essences penetrate better into the deep layers of the dermis. The third mode is lifting, which helps to tighten the oval of the face due to micromassage.
⚠️ Warning: Do not use the "Nutrition" mode immediately after mechanical cleaning if there are open inflammations or wounds on the skin.
Battery life is usually about 1 hour of continuous use, which is equivalent to 20-30 full procedures. The battery charge indicator signals the need to connect to the network. The standard micro-USB or USB-C cable is used to charge, depending on the year of release of your model.
Technical features of ultrasound
Step-by-step instructions: cleaning technique
The procedure should be started by setting the correct angle of inclination of the shoulder blade. The optimal angle is 45 degrees relative to the skin surface. If you hold the device perpendicularly (90 degrees), the cleaning efficiency drops sharply as the contact area decreases, and the risk of scratching the skin with a sharp edge of the metal plate increases.
The movements should be smooth, sliding and slow. Don't drive the shoulder blade back and forth like ironing laundry. Move strictly along the massage lines: from the center of the forehead to the temples, from the nose to the ears, from the chin to the earlobes. Pay special attention to the T-zone (forehead, nose, chin), where the pores are most prone to blockage. 2-3 seconds.
- 🧖♀️ Move from the bottom up so as not to disturb the natural lymphatic drainage and not provoke sagging of the skin.
- 💧 Constantly monitor the moisture of the skin: if the shoulder blade stops "squeaking" or slides with a characteristic hissing sound, sprinkle your face with water.
- 🚿 Avoid areas around the eyes and lips where the skin is too thin and sensitive to ultrasound.
After you've gone through all the areas of your face, wipe your shoulder blade with a soft napkin, and you'll see a gray coating on it, which is the removed contamination, and if you've got a lot of plaque, you can do it again in a week, but not more often, and excessive brushing can thin the corneal layer of your skin.
Use of cosmetics: what can and can not
Conductive environments are a science that determines the outcome: you can't use regular tap water because they evaporate quickly and can contain skin irritants, and you can't use pure oils for cleaning mode, because they're too viscous and block the ultrasonic wave from spreading, making the device a normal vibrator.
The ideal choice would be:
- 🌿 Hydrolate is natural flower water, perfectly conducts ultrasound and soothes the skin.
- 🧴 Special lotion for ultrasonic cleaning - sold in professional cosmetic stores.
- 💦 Micellar water is an affordable alternative if there are no oils and alcohol in the composition.
In the Import mode, on the contrary, you can and should use serums with hyaluronic acid, peptides or vitamins. Ultrasound helps active molecules to overcome the lipid barrier of the skin. However, avoid products with a dense texture or metal particles (for example, some film masks), as they can damage the coating of the shoulder blade.
💡
To enhance the cleaning effect, apply enzyme powder mixed with tonic to the skin, enzymes dissolve the protein bonds of contaminants, and ultrasound easily removes their residues.
Table: Comparison of Scrabber modes
To organize information about the functionality of the device, consider the basic parameters of operation in different modes, which will help you to navigate faster in operation.
| Regime. | Frequency of oscillation | Substantive function | Recommended time |
|---|---|---|---|
| Cleaning (Cleaning) | 24,000 - 30,000 Hz | Removal of black dots, keratinized cells | 3-5 minutes |
| Nourishing (Fooding) | Low-frequency pulsation | Deep serum penetration | 3-5 minutes |
| Lifting (Lifting) | Microvibration | Muscle tone, improvement of microcirculation | 2-3 minutes |
Switching between these modes allows you to perform a full spa treatment at home, and by combining the steps, you get a comprehensive care: first a deep cleanse, then a saturation with nutrients and a final massage to consolidate the result.
Care of the device and precautions
The ultrasonic blade is made of medical steel, but this does not mean that it does not require careful treatment.After each procedure, the device must be thoroughly wiped with a soft cloth soaked in disinfectant solution or alcohol (only the working surface), it is better to store the scrubber in a protective case to avoid dust and moisture on the charging contacts.
⚠️ Warning: Never immerse the device body in water, even if it is labeled waterproof.Waterproof is usually only about splashes, not full immersion.
Charge the device only from USB-The use of powerful fast charging units from smartphones can damage the power controller inside the scrubber, reducing its life. If the device stops turning on, check the contacts for oxidation.
There are contraindications to the use of ultrasound: Do not clean if there are purulent inflammations (acne in the acute stage), herpes, cancer, pregnancy or installed pacemakers. Ultrasound can increase the inflammatory process or provoke the spread of infection through the lymph flow.
💡
Regular disinfection of the shoulder blade with an alcohol solution after each use prevents the skin from being re-infected with bacteria.
