RF, EMS, Ultrasound & ВЕЛ: Understanding the Core Technologies in Modern Beauty Devices
Modern at-home beauty devices combine multiple technologies to help improve skin health, reduce signs of aging, and enhance skincare absorption. While many of these functions may sound high-tech, their underlying principles are quite straightforward. Below is a summary of the most common technologies and how they work.
Vibration
This basic function uses a small motor with an off-balance disc to create vibrations. When applied to the skin, vibration helps reduce puffiness and gives a temporary skin tightening effect, especially useful in the morning for a refreshed look. The results are immediate but short-lived, making it more of a quick fix than a long-term solution.
Ultrasound
Ultrasound technology uses high-frequency vibrations to break down large skincare molecules into smaller ones, improving skincare absorption. Since many active ingredients cannot penetrate the skin barrier on their own, ultrasound ensures they reach deeper layers. Although results are not instant, consistent use enhances hydration and skin texture over time.
Ion Import and Export
This technology leverages positive and negative ions:
Negative ion import: Boosts penetration of Vitamin C, kojic acid, peptides, and other active ingredients.
Positive ion export: Draws out deep impurities for thorough pore cleansing.
Ion technology is especially effective for brightening treatments and achieving clearer, smoother skin.
RF Radio Frequency (RF Skin Tightening)
Commonly known as thermage or radio wave lifting, RF skin tightening devices use high-frequency electromagnetic waves to heat deeper skin layers. At 68–72°C, collagen fibers contract immediately, giving a firming effect, while stimulating new collagen production for longer-term results.
This technology is highly effective for reducing wrinkles and sagging skin, particularly for users over 40 when topical creams alone may not be enough.
EMS Microcurrent
EMS microcurrent facial devices send gentle electrical pulses directly to muscles, causing contractions similar to exercise. This stimulation improves facial contours, enhances ATP production, and supports collagen generation.
Benefits include lifting, skin firming, reducing fine lines, and even body contouring when applied to other areas. The effects are visible quickly but less long-lasting than RF treatments.
LED Red and Blue Light Therapy
LED light therapy is one of the most popular non-invasive beauty treatments:
Red light therapy (630–660 нм): Stimulates collagen, уменьшает морщины, tightens pores, and promotes wound healing.
Blue light therapy (вокруг 415 н.м.): Destroys acne-causing bacteria, calms inflammation, and regulates oil production.
This makes LED red and blue light therapy effective for both anti-aging care and acne-prone skin.
Cryotherapy (Cooling)
Cryotherapy devices use semiconductor cooling to lower skin temperature close to 0°C. Applied after treatment, cooling helps shrink pores, lock in moisture, and soothe irritation. It functions similarly to the cooling effect of a refrigerator, providing a refreshing finish to skincare routines.
Skin Moisture Detection
Modern devices often include skin hydration analyzers with two methods:
Bioelectrical impedance: Measures resistance to calculate moisture levels.
Capacitance method: Detects water content based on dielectric properties.
This feature is practical for tracking skincare effectiveness and is even used at cosmetic counters for quick skin analysis.
