Dual RF + Ultrasound
New Doublo 2.0 combines three technologies — ultrasound (HIFU), radiofrequency (RF) and microneedle RF — to act on different layers of the skin. Through RF + ultrasound + microneedle RF, one machine delivers three effects and a full-layer structural aesthetic for comprehensive rejuvenation. The new generation has been upgraded from four handpieces to five, adding the microneedle RF function.
Three Layers of Full-Layer Structural Aesthetics
- Deep fascial layer (SMAS): responsible for support and lifting
- Mid subcutaneous tissue: affects fullness and elasticity
- Superficial dermis: governs refinement, smoothness and firmness
Three Functional Handpieces
★ FL Ultrasound
- Six depth probes from 1.5mm to 9.0mm
- Skin-contact firing mechanism
- Dot mode: point heating to enhance firming and lifting
- Linear mode: volumetric heating to strengthen fat-dissolving efficiency
- U-TURN bidirectional output mode: shortens treatment time by about 25%
★ SD Electro-Ultrasound (RF + HIFU)
- Patented "2 in 1" probe: simultaneously outputs RF and ultrasound energy
- RF: volumetric heating of the dermis to stimulate collagen remodeling
- Ultrasound: penetrates the SMAS fascial layer for precise lifting
Effects and Duration
- Immediate effect: feel improved firmness right after treatment
- Peak performance: most evident 1-3 months later
- Duration: about 6-12 months; regular maintenance is recommended alongside good lifestyle habits
Frequently Asked Questions (FAQ)
Q1 Why do "full-layer lifting"? Traditional treatments act on a single layer with limited results. Doublo's full-layer treatment improves lifting force, firmness and skin-texture improvement.
Q2 Does the treatment hurt? Numbing cream is applied before treatment; most areas are gentle, with only a hot, prickling sensation possible near bone. Energy is adjusted according to individual tolerance.
Q3 Are there side effects? A few people may experience brief redness, swelling, numbness or tenderness, usually resolving within a few hours to a few days. Overall it is a highly safe, non-invasive treatment.
Q4 Is downtime needed? There is almost no recovery period; after treatment you can immediately resume daily life and apply makeup as usual.
Q5 How soon are results visible? How long do they last?
- Immediate feel: firmness, lifting
- Best results: 1–3 months
- Duration: about 9–12 months
Q6 Is one session effective? How many are needed? Most people see results after a single session; regular maintenance once every 8–14 months is recommended.
Q7 How long does treatment take? About 30-50 minutes, varying with the number of shots and the treatment area.
Q8 How many shots are needed? General recommendation:
- Ultrasound: 600–800 shots
- SD electro-ultrasound: 5,000–8,000 shots
Q9 Can it be combined with other treatments? It can be paired with fillers, botulinum toxin, laser, thread lifting and other treatments. If injection or filling is needed in the same area, please discuss the interval and sequence with your physician.
Pre-Treatment Precautions
- Avoid irritating products such as retinoic acid, salicylic acid and glycolic acid for 7 days before treatment
- If the treatment area has wounds, peeling, redness, inflammation or sunburn, wait until it has recovered before proceeding
- Inform the physician in advance of any prior fillers, thread lifting, surgery or other aesthetic treatments
Post-Treatment Precautions
- Avoid exfoliation, irritating skincare products and high-temperature environments (steam room, sauna, hot spa) within one week
- Mild redness, swelling, tightness or tingling are normal reactions that ease within 1–3 days
- Strengthen moisturizing and gentle repair
- Use SPF 30 or higher sunscreen and reapply regularly; avoid sun exposure
