1. What is LDM?
LDM (Low-frequency Dual-frequency Modulated) is a dual-frequency modulated ultrasound technology that rapidly alternates between low and high frequencies to drive skin regeneration at the cellular level.
Unlike conventional ultrasound devices, LDM modulates between 1 MHz, 3 MHz, and 10 MHz hundreds of times per second to deliver optimal cellular stimulation. This maximizes the skin's self-regeneration capacity and addresses a range of skin concerns at the root.
Core Features of LDM
Dual-Frequency Modulation
Ultra-fast switching between low and high frequencies maximizes cellular stimulation.
Cellular-Level Action
Directly activates biological responses in skin cells.
Non-Invasive Treatment
Effective delivery into the dermis without damaging the skin.
2. How LDM Works
LDM's low-frequency ultrasound gently stimulates skin-cell membranes to trigger a range of biological responses.
Boosts Hyaluronic Acid Production
Ultrasound stimulation activates fibroblasts, increasing the skin's natural hyaluronic acid synthesis. This raises moisture-retention capacity and improves elasticity.
Stimulates Collagen & Elastin Synthesis
Activated dermal fibroblasts produce more collagen and elastin, strengthening the skin's structural support and restoring firmness.
Anti-Inflammatory Effect
LDM ultrasound suppresses inflammatory cytokines and activates anti-inflammatory factors, effectively calming inflammation and irritation.
Improved Cellular Permeability
Ultrasound energy temporarily increases cell-membrane permeability, maximizing skin absorption of active ingredients.
3. LDM Applications
Skin Regeneration & Calming
Accelerates regeneration of damaged skin and quickly soothes sensitive or irritated skin.
Acne Scar Improvement
Collagen remodeling gradually improves indented acne scars and refines skin texture.
Pigmentation Reduction
Accelerates skin turnover to improve pigmentation and even out skin tone.
Post-Surgical Recovery
Speeds resolution of post-operative swelling, bruising, and scarring; supports tissue regeneration for the best result.
Hydration & Elasticity
Boosts hyaluronic acid production to hydrate skin from the inside out and restore elasticity.
Sensitive-Skin Care
Calming and regeneration without irritation — suitable for sensitive and rosacea-prone skin.
4. Advantages of LDM
Pain-Free Treatment
Virtually no pain during treatment — comfortable without any anesthesia.
Zero Downtime
Immediate return to daily life; makeup is fine the same day.
Sensitive-Skin Friendly
Non-invasive with almost no skin irritation — safe even for sensitive skin.
Combinable with Other Treatments
Combines well with laser, filler, or Botox treatments for synergistic results.
5. Treatment Schedule
Recommended program for the best results
Every 1–2 Weeks
Treatments are scheduled every 1–2 weeks depending on skin condition and treatment goals.
5–10 Sessions Recommended
The base program is 5–10 sessions, adjusted to skin condition. Consistent treatment compounds the regenerative effect for healthier skin.
Maintenance Schedule
After the initial program, a maintenance session about once a month helps keep skin condition consistently good.
Note: The exact number of sessions and interval are determined after consultation, based on your individual skin condition.
