Cartessa (mfg ShenB) Virtue RF

The science

The platform delivers bipolar RF through 36-needle cartridges (gold-coated on DeepRF) with selectable 0.5/1/2 MHz frequencies — lower frequencies push energy deeper, higher frequencies concentrate it, giving real dosimetry flexibility across skin types. Its Robotic Precision Delivery motorizes needle insertion for smooth, consistent depth, and proprietary sub-pulsing splits each energy delivery into fragments that maintain total fluence while dramatically improving comfort — many patients do it with topical numbing only. DeepRF adds a cooling plate and deeper penetration for body laxity; ExactRF's single needle enables periorbital precision no stamping handpiece can match. Collagen remodeling follows the standard RF-MN arc: visible tightening at 6-12 weeks, three-session protocols standard.

Patented tech

ShenB's Robotic Precision Delivery motorized insertion system and the exclusive RF sub-pulse energy-fragmentation scheme are the platform's protected differentiators, along with the multi-frequency (0.5/1/2 MHz) delivery architecture that Cartessa markets as broader than any competing clearance.

Origin

South Korea (ShenB Co., Ltd., Seoul); distributed exclusively in the US by Cartessa Aesthetics, Melville, NY.

Best-fit practice

Established medspas and derm/plastics practices in competitive metros that need a marketable, comfort-forward RF-MN brand to defend against the Morpheus8 shop down the street, and practices doing enough volume (10+ treatments/month) to amortize a six-figure buy. Overkill for a startup that just needs an RF-MN checkbox.

Medical director & delegation

Standard RF microneedling rules apply: medical director, good-faith exams, and state-specific delegation determining whether RNs, NPs, or (rarely) aestheticians can operate. Cartessa's clinical onboarding is good, but it doesn't substitute for written protocols your medical director actually signs.

Contraindications & screening

Implanted electronic devices, pregnancy, active infection or herpetic outbreak in the field, keloid propensity, recent isotretinoin, and metal implants in the treatment zone. The multi-frequency flexibility and insulated options make it workable across all Fitzpatrick types with conservative settings.

Warranty & service

Cartessa includes a 1-year warranty standard with extended plans typically $8,000-$12,000/year thereafter, and its service reputation is better than most distributors — loaner support and responsive reps are consistently reported. As a distributor-model device, long-term parts continuity depends on the Cartessa-ShenB relationship staying healthy.

Resale & used market

Used units from 2020-2023 trade around $25,000-$45,000, a steep but category-normal depreciation curve; the consumable lock and Cartessa's control of tips suppress secondary-market values. Buy for treatment revenue over a 5-year hold, not for exit value.
