Immediate lifting. Lasting results. Destiny by Jeisys is the only dual-mode radiofrequencytreatment designed for comfort.


Density combines two types of radiofrequency energy delivered in sequence. Monopolar RF penetrates deep into the dermis and subcutaneous layers, triggering collagen remodeling that builds over time. Simultaneously, bipolar RF targets the upper dermis for immediate tightening and texture refinement.
The result: your skin looks and feels lifted right away, and keeps improving as new collagen develops. Most patients see noticeable results after one or two treatments, spaced 4–6 months apart. Treatment takes 20–30 minutes. You return to normal activity immediately.


Density comes from Jeisys, a South Korean medical aesthetics company with 25+ years of innovation and over 15,000 systems installed worldwide. Korean dermatology has been leading non-invasive skin technology for decades. Now it's here.
LA's aesthetic market demands results without compromise: no surgery, no months of healing, no visible recovery. Density delivers. It's the kind of precision engineering and clinical validation Korea has perfected, applied to what your skin actually needs.
The bipolar component delivers immediate surface tightening while monopolar goes deep—true dual-mode technology. Treatments like Xerf use two monopolar frequencies, which don’t allow for quick healking. More importantly, Density patients don't need numbing cream before treatment, which means no waiting, no extra steps: just results.


Visible skin tightening and lift within hours of treatment.


Mild redness or swelling for afew hours (optional). Most people return to work or social plansthe same day.


Continued improvement over 4–6 weeks as new collagen builds. Peak results at 2–3 months.


Results last 6–12 months. Annual maintenance treatments extend and preserve your improvements.
Density treatments produce a 239% increase in newly synthesized collagen, 76% increase in collagen fiber density, and 82% increase in elastin fiber density. (Citation)

Density is a dual-mode radiofrequency treatment developed by Jeisys, a South Korean medical aesthetics company, that combines monopolar and bipolar energy in a single session. Monopolar RF penetrates deep into the dermis and subcutaneous layers to stimulate long-term collagen remodeling and structural improvement, while bipolar RF targets the upper dermis for immediate surface tightening and texture refinement. This dual-mode approach is fundamentally different from single-frequency RF devices like Thermage or Xerf, which use monopolar energy only. Clinical studies show Density boosts collagen density up to five times more than traditional single-mode devices. At Hazany Derm, Dr. Salar Hazany uses Density as part of a comprehensive skin rejuvenation strategy, combining it with other treatments when appropriate to deliver results that address both immediate lifting and long-term skin quality.
Density is specifically engineered for patient comfort, and this is one of its defining advantages over competing RF technologies. The device includes integrated cryogen cooling that delivers a cooling pulse alongside each energy pass, significantly reducing discomfort. Topical numbing is applied beforehand, so most patients experience gentle, controlled warmth rather than pain. Unlike Xerf and some other RF treatments that often require numbing cream (which adds 30–45 minutes to your appointment and creates delays), Density patients typically don't need additional numbing at all. Dr. Hazany and his team at Hazany Derm have built the Density experience around comfort—no unnecessary waiting, no guessing about pain levels. Patients consistently report that the treatment feels manageable and tolerable, making it accessible to those who've avoided RF treatments in the past due to discomfort concerns.
Most Density treatments at Hazany Derm take 20–30 minutes, depending on the area being treated and the extent of the concern. Because numbing cream isn't required—a key difference from other RF systems—there's no additional waiting time built into your appointment. Dr. Hazany and his team have streamlined the process so you can get in, receive your treatment, and return to your day without unnecessary time investment. The efficiency of the treatment doesn't compromise results; it simply respects your schedule while delivering the same clinical outcomes.
Density is virtually downtime-free, which makes it ideal for busy professionals and anyone who wants visible results without recovery disruption. Some patients may experience mild redness or slight swelling for a few hours immediately following treatment, but this resolves quickly and doesn't prevent normal activity. You can return to work, social events, exercise, and your regular routine the same day. This is one of the major advantages Density offers over invasive procedures or treatments with significant healing periods. Dr. Hazany at Hazany Derm emphasizes this benefit to patients who've been hesitant about aesthetic treatments due to downtime concerns—Density delivers real, visible improvement without the lifestyle disruption.
Density is ideal for a broad range of patients. The experts at Hazany Derm recommend Density for anyone experiencing early to moderate skin laxity, crepey or textured skin, fine lines, or loss of firmness from aging or weight change. It's also an excellent "collagen banking" treatment for those in their 30s and 40s who want to maintain skin structure proactively before more significant aging changes occur. Density is suitable for all skin types and tones, making it one of the most versatile non-invasive tightening options available. During your consultation, Dr. Hazany will evaluate your specific skin concerns, assess your skin type and condition, and determine whether Density alone is the right choice or whether combining it with other treatments would better serve your goals.
Yes, absolutely. Density complements many aesthetic treatments beautifully when strategically combined. The experts at Hazany Derm frequently recommend pairing Density with injectables, facials, microneedling, or other skin rejuvenation procedures to address multiple concerns simultaneously—structural tightening, volume, fine lines, and skin texture all in one comprehensive plan. Dr. Salar Hazany takes a holistic approach to aesthetic medicine, meaning he considers your entire face and skin quality, not just one concern. During your consultation, he'll discuss your full aesthetic goals and recommend a personalized treatment protocol that may include Density alongside complementary procedures. This integrated approach typically yields superior results compared to treating concerns in isolation.
