How It Works

Density combines two types of radio frequency 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.

COMPARISON

Skin Tightening with a
Difference You Can Feel

Density

No numbing required
Dual-mode energy (monopolar + bipolar)
Topical comfort cooling integrated
Designed for patient comfort from the ground up

Xerf

Numbing often needed (adds 30–45 min)
Single-mode energy (monopolar only)
Cooling system present but less advanced
Described as 2–3 out of 10 pain level

Density was engineered around one principle:
effective doesn't have to hurt.

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 healing. More importantly, Density patients don't need numbing cream before treatment, which means no waiting, no extra steps: just results.

THREE HANDPIECES

One Device, Three Precision Handpieces

Density isn't a one-size-fits-all treatment. The system uses interchangeable handpieces, each engineered for a specific area of the body, so the energy delivered to your delicate under-eye skin is never the same as the energy delivered to your abdomen. This lets Dr. Hazany match the right depth, intensity, and tip size to the treatment area for the safest, most effective results.

Eye Tip — For the Lower Eyelid & Periorbital Area

The skin around the eyes is thinner and more delicate than anywhere else on the face, so it requires a smaller, gentler applicator. The Eye Tip is purpose-built for the periorbital region, delivering precisely controlled RF energy to:

Tighten crepey or lax skin on the lower eyelid

Soften the look of under-eye bags and fine lines

Improve overall firmness around the eyes

Because the tip is scaled to this smaller treatment area, Dr. Hazany can work close to the lash line and orbital bone with a level of control that a larger, full-face tip can't offer — with no needles and virtually no downtime.

Face & Neck Tip — For the Jawline, Cheeks & Neck

This is the workhorse handpiece for facial rejuvenation. Sized for broader coverage than the Eye Tip but still precise enough for contoured areas like the jawline, the Face & Neck Tip delivers Density's signature dual-mode monopolar and bipolar energy to:

Redefine and tighten the jawline
Smooth and firm the neck and submentum (under-chin area)
Improve firmness and texture across the cheeks and midface

This is the handpiece most commonly used for classic "lower face and neck" tightening sessions, and it's often the starting point for patients new to Density.

Body Tip — For the Abdomen, Arms, Thighs & Beyond

Body skin is thicker and treatment areas are larger, so the Body Tip is designed to cover more surface area efficiently while still delivering the same dual-mode RF energy that drives Density's collagen-building results. It's used to treat:

Abdominal skin laxity
Upper arms
Inner thighs and other areas prone to looser skin

The larger applicator surface means body sessions can move efficiently across bigger treatment zones without sacrificing the consistent, comfortable energy delivery Density is known for.

FAQ

Frequently Asked Questions

What is Density by Jeisys and how does it differ from other skin tightening treatments?

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.

Is Density skin tightening painful?

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. 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.

How long does a Density skin tightening treatment take?

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.

Is there any downtime after Density by Jeisys?

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.

Who is a good candidate for Density by Jeisys skin tightening treatment?

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.

Can I combine Density by Jeisys with other skin treatments?

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.

Is Density by Jeisys FDA-cleared?

Yes, Density by Jeisys is FDA-cleared for dermatologic and surgical procedures. It's backed by over 25 years of innovation and clinical research from Jeisys, a leading South Korean medical aesthetics company with over 15,000 systems installed globally. The device has undergone rigorous safety and efficacy testing, and independent clinical studies demonstrate measurable collagen production, increased collagen fiber density, and improved elastin after treatment. At Hazany Derm, Dr. Hazany uses only FDA-cleared, clinically validated technologies. You can be confident that Density is not only safe and effective, but represents the current state-of-the-art in non-invasive skin tightening.

What areas can be treated with Density skin tightening?

Density can effectively treat the face, neck, jawline, décolletage, and body areas experiencing skin laxity or loss of firmness. Common treatment areas at Hazany Derm include the lower face and jowls, neck and submentum, cheeks and midface, forehead, and body areas like the abdomen or inner thighs. The device is customizable, allowing Dr. Salar Hazany to adjust energy settings and treatment depth based on the specific area and your individual skin characteristics. During your consultation, Dr. Hazany will assess your concerns, explain which areas would benefit most from Density, and create a treatment plan tailored to your anatomy and goals.

Why choose Hazany Derm for Density by Jeisys skin tightening treatments?
