What Is LDM Ultrasound? How Daily At-Home Ultrasound Supports Skin Hydration and Texture

⚠️ Important: The SENNEY™ Athena LDM Handpiece must be used with the SENNEY™ Athena 5-in-1 system. It cannot be used or purchased as a standalone device.

LDM ultrasound — or Local Dynamic Micro-massage — is an advanced multi-frequency ultrasound technology designed to support deep skin hydration, texture, and firmness at home. The SENNEY™ Athena LDM Handpiece brings this professional-grade LDM device technology into your daily skincare routine.

What Is LDM Ultrasound Technology?

LDM — which stands for Local Dynamic Micro-massage — is an advanced ultrasound technology that uses low-frequency dynamic micro-ultrasonic energy to support the skin at multiple depths. Unlike traditional single-frequency ultrasound devices, LDM uses multiple frequencies simultaneously or in sequence, allowing it to target different skin layers in a single session.

Originally developed for professional aesthetic use, LDM technology is now available for at-home skincare through the SENNEY™ Athena LDM Handpiece — as part of the Athena 5-in-1 system.

How Does LDM Ultrasound Work on Skin?

LDM ultrasound works by delivering gentle, rhythmic micro-vibrations into the skin at specific frequencies. The SENNEY™ Athena LDM Handpiece uses four targeted frequencies, each calibrated to support a specific skin depth:

• 1MHz — Deep Fascia & Muscle Layer: Supports the visible appearance of skin firmness and may help improve the look of facial definition
• 3MHz — Subcutaneous Layer: May help reduce the appearance of puffiness and support a more sculpted-looking facial contour
• 10MHz — Dermal Layer: Supports the visible appearance of skin elasticity and may help reduce the look of fine lines
• 19MHz — Epidermis & Stratum Corneum: Supports the skin barrier, enhances active ingredient absorption, and promotes a more hydrated, soothed-looking complexion

By combining these frequencies — either in fixed or variable modes — LDM may support a range of visible skin improvements from surface hydration to deeper firmness support. Individual results may vary.

Two Working Modes

Fixed Frequency Mode — Targeted Zone Care
Select a specific frequency (1 / 3 / 10 / 19MHz) to focus on a particular skin depth and concern. Ideal for targeted, zone-specific skincare.

Variable Frequency Mode — 1–19MHz Intelligent Switching
The device automatically identifies skin thickness and dynamically adjusts frequencies across the full range (1–19MHz), delivering simultaneous multi-layer skin support in a single session. Gentle, easy to use, and suitable for all skin types.

What Skin Concerns May LDM Ultrasound Help Address?

Deep Hydration Support

LDM's multi-frequency energy may help drive active ingredients deeper into the skin, supporting more effective hydration from your serums and moisturisers. Skin may appear more plump and hydrated with consistent use.

Skin Texture Improvement

Regular LDM treatment may support the skin's natural renewal process, helping to smooth the appearance of rough or uneven skin texture over time. Individual results may vary.

Firmness and Elasticity Appearance

LDM may help improve the visible appearance of skin firmness and elasticity — supporting a more resilient, youthful-looking complexion with consistent use.

Puffiness and Dullness

The 3MHz frequency may help reduce the appearance of puffiness, while the combined multi-frequency modes may support a more radiant, refreshed-looking complexion.

Pore Appearance

LDM may help support a smoother, more balanced-looking skin surface, helping to reduce the visible appearance of enlarged pores over time.

LDM vs Standard Ultrasound Devices: What's the Difference?

Most consumer ultrasound beauty devices operate at a single fixed frequency — typically 1MHz or 3MHz. While beneficial, single-frequency devices can only target one skin depth at a time.

The SENNEY™ Athena LDM Handpiece uses four frequencies (1MHz / 3MHz / 10MHz / 19MHz) in both fixed and variable modes, allowing it to address multiple skin depths in a single session — from deep fascia support to surface hydration and barrier care. This multi-frequency approach is what distinguishes LDM from standard at-home ultrasound devices.

How to Use the LDM Handpiece at Home

Step 1: Cleanse thoroughly
Start with clean skin. Remove all makeup and skincare products before treatment.

Step 2: Apply your serum
Apply your preferred serum or active ingredient before use. LDM may help drive active ingredients deeper into the skin, maximising the effectiveness of your skincare products.

Step 3: Select your frequency mode
Choose Fixed Mode for targeted zone care, or Variable Mode (1–19MHz) for a comprehensive full-face treatment.

Step 4: Treat in sections
Move the handpiece slowly across each area of the face — forehead, cheeks, jawline, and neck. Follow the recommended session duration in your user manual.

Step 5: Apply moisturiser
After treatment, apply your moisturiser to seal in hydration. Post-LDM skin may be primed for improved absorption.

Step 6: Use consistently
LDM is gentle enough for daily use. For best results, incorporate it into your regular skincare routine. Refer to your device's user manual for recommended frequency.
