Dual-frequency megahertz ultrasound — the medical-grade facial that heals, hydrates and rebuilds your skin barrier from within. No heat. No downtime. Immediate radiance.
LDM® (Low Dose Megahertz) is a dual-frequency therapeutic ultrasound technology delivering precisely calibrated energy at two frequencies simultaneously. Unlike single-frequency ultrasound facials, LDM's dual-frequency mode creates a resonance effect within the skin that stimulates collagen without thermal damage, reduces inflammation and accelerates cellular repair.
Originally developed for wound healing and dermatological conditions, LDM is now deployed as a premium medical-grade facial at Dr Sin Yong's Orchard Road practice — addressing dehydration, barrier compromise, post-procedure recovery and early ageing signs. Suitable for all skin types including sensitive and reactive skin.
Dr Sin Yong assesses your skin condition and selects the optimal LDM frequency combination and coupling medium. Medical-grade gel ensures optimal ultrasound transmission throughout the treatment area.
The LDM handpiece alternates between two megahertz frequencies across treatment zones. The lower frequency penetrates the dermis, stimulating collagen and elastin. The higher frequency targets the epidermis, improving hydration, strengthening the barrier and accelerating cellular turnover.
Immediately post-LDM, the skin is in an optimal state of permeability. Medical-grade serums — hyaluronic acid, growth factors or niacinamide — are applied and their absorption is significantly enhanced by the residual ultrasound effect on the skin barrier.
Non-thermal, non-ablative. No redness, no peeling, no recovery. Immediate return to all activities.
Megahertz frequencies have clinically demonstrated anti-inflammatory properties — uniquely suited for reactive, post-procedural skin.
Significantly enhances transdermal water retention. Patients report sustained hydration improvements lasting days beyond treatment.
Mechanical vibration at megahertz range stimulates fibroblast activity and collagen synthesis — safe for all Fitzpatrick skin types including IV–VI.
Highly effective after laser resurfacing, chemical peels or injectables. Reduces recovery time and enhances treatment outcomes.
No chromophore restriction, no PIH risk — suitable for the full range of Singapore skin tones.
LDM® (Low Dose Megahertz) is a dual-frequency therapeutic ultrasound facial available at Dr Sin Yong's practice on Orchard Road, Singapore. It uses two ultrasound frequencies simultaneously to target different skin depths — stimulating collagen, reducing inflammation and accelerating skin repair with zero downtime.
Yes — LDM is one of the most sensitive-skin-friendly energy treatments available. Its non-thermal, non-ablative mechanism makes it safe for reactive skin, rosacea and post-procedural recovery states.
Traditional ultrasound facials use single frequencies primarily for heating tissue. LDM uses dual megahertz frequencies creating a resonance effect — stimulating collagen and improving hydration without thermal energy.
A course of 4–6 sessions spaced 1–2 weeks apart is recommended for optimal results. Monthly maintenance thereafter. Dr Sin Yong personalises your protocol based on skin condition and goals.
Yes — LDM pairs excellently as a pre-treatment primer or post-treatment recovery modality alongside laser resurfacing, RF microneedling or injectables at Dr Sin Yong's practice.
Available on Orchard Road, Singapore. By appointment.
