When will I feel elasticity after DENSITY?

With DENSITY, you may feel a slight tightening immediately after the procedure as collagen contracts from the heat. Over the following two to three months, as new collagen settles, changes in contour and elasticity gradually become more noticeable. The speed of results can vary depending on your skin condition.

I heard DENSITY is very painful. Is anesthesia really necessary?

Since DENSITY delivers energy while the cooling system lowers the surface temperature, most patients undergo it comfortably with numbing cream. However, for areas close to the bone or for those sensitive to pain, the numbing time can be adjusted after consultation, and the intensity can be adjusted during the procedure, so please let us know comfortably.

Can I wash my face and apply makeup right after DENSITY?

DENSITY requires no separate recovery period, so you can wash your face and apply light makeup immediately after the procedure. Redness or a feeling of heat may remain, but it usually subsides within a few hours to a day, so you can schedule it before or after work. If you have an important event, allowing about a day of buffer time will be more comfortable.

How long do DENSITY results last?

Because DENSITY involves a process where newly formed collagen settles, changes tend to last relatively long, typically around six months. However, the duration can vary from person to person depending on age, sun exposure, and lifestyle habits.

Is one DENSITY treatment enough, or should I get it every few months?

With DENSITY, even a single treatment can stimulate collagen production, so the burden of multiple sessions is not high. Typically, maintenance is done around every six months, and for more advanced sagging, the number of shots may be divided across several sessions, which we will decide together during your consultation.

Does DENSITY make your face look thinner or cause side effects?

DENSITY lowers the risk by adjusting energy and depth to target dermal elasticity, but depending on skin thickness and fat volume, rare side effects such as cheek hollowing, burns, or temporary numbness may occur. A consultation before the procedure will confirm suitability, and if blisters or pain persist, let us know right away.

Filling both the surface and the deeper layers DENSITY

A dual RF lifting treatment that combines monopolar and bipolar energy in a single shot, filling every layer of the skin — from the surface to the deep dermis — without gaps.

Treatment Time: About 30 minutes
Anesthesia: Topical anesthetic cream
Recovery Time: Minimal downtime
Recommended Interval: 1–2 times per year

Anti-Aging RF Lifting

density

What is DENSITY?

A lifting device that delivers monopolar radiofrequency (RF) energy to the dermal layer, stimulating collagen contraction and regeneration. It is used to improve overall facial skin laxity, sagging, and fine wrinkles.

01 Lifting
02 Elasticity
03 Tightness

Mechanism

How DENSITY works

DENSITY delivers monopolar RF energy through a dedicated tip to the dermal layer. When heat is applied, loose collagen contracts immediately, providing a sense of firmness, and then new collagen gradually fills in. During the treatment, the device measures the skin's impedance to adjust the energy, and a cooling system protects the epidermis. This ongoing process of contraction and regeneration helps improve facial sagging, fine wrinkles, and loss of elasticity.

HEALHOUSE’S density

DENSITY at Heal House is different

HEAL POINT 01

Genuine products Accurate shots Exact dosage

All five Heal House branches use only genuine products, under the same standards. This applies to tips, cartridges, and medications alike. We use the agreed number of shots and dosage as planned, and disposable supplies are never reused. We deliver the exact amount precisely where it is needed.

HEAL POINT 02

Same procedure, different design

Even with the same equipment and medication, results vary depending on who receives the treatment and how it is applied
. This is because skin type, thickness, and degree of sagging differ from person to person. A higher number of shots or larger dosage does not necessarily mean better results.
A different design leads to different outcomes.
