Medical-grade skin rejuvenation

RejuvLab introduces Density, a new-generation high-frequency RF device from Jeisys Medical, South Korea, applying dual-mode radiofrequency technology including monopolar RF and bipolar RF. This technology is US FDA cleared and South Korean MFDS certified for controlled collagen remodeling procedures in dermatology. Operating at 6.78 MHz, Density sequentially acts on both superficial and deep skin layers to support multi-layer lifting, firming and restructuring. With a 6.78 MHz frequency, Density's monopolar RF penetrates deep into the sub-dermal fat layer and supporting tissue system, contracting connective tissue and improving the contour of the face and double chin. Meanwhile, bipolar RF concentrates in the dermis and epidermis, stimulating collagen and elastin proliferation while improving elasticity, smoothness and skin surface quality. Highlight features of Density lie in its powerful energy delivery of up to 400W per pulse, combined with a smart control system ensuring stable, uniform energy across the treatment region. Real-time impedance feedback technology automatically adjusts energy for each skin zone, while a 5-step cooling system protects the epidermis, reduces heat discomfort and increases comfort during treatment. Thanks to its multi-layer mechanism, Density is suitable for sagging, loose skin, wrinkles, fine lines, rough or dull skin, enlarged pores or mild excess fat in the double chin and lower cheeks. This is an appropriate choice for customers seeking facial lifting, slimming, skin quality improvement and deep rejuvenation without surgery, especially for those unsuitable for HIFU or desiring a gentler treatment experience.
