As an Assistant Professor, Associate Ward Director, and Chief of Dermatopathology at the university hospital dermatology department, I deepened my expertise through academic presentations and paper publications both domestically and internationally. I have handled a wide range of treatments, from birthmark therapy in children to adult pigmentation concerns, utilizing various lasers and injection therapies, while also contributing to community healthcare. Through encountering numerous cases, I strongly felt the potential and necessity of aesthetic medicine, resolving to pursue further expertise. Building upon my solid dermatological knowledge and meticulous diagnostic skills, I value treatments that gently support each individual's skin while bringing out its inherent beauty.

Dark circles under the eyes. I can't keep up with the aging changes... I've tried all sorts of things, but this!!

Here is a combination of treatments we offer.

 

I am Dr. Aya Hayama, a board-certified dermatologist.

Dark circles under the eyes... Since they become a prominent feature on the face, alongside wrinkles and sagging, many people are concerned about them, aren't they?

For those with sagging fat forming tear troughs, those troubled by numerous wrinkles, and those troubled by pronounced hollows.

Dark circles under the eyes can vary greatly.

This time, I thought it might also help prevent tear troughs, so I'm writing this article.

Along with photoaging, one of the changes that comes with aging is skinDecrease in dermal collagen

So how should we go about generating it? I want to examine that very question.

 

You see, I overheard a bit from a surgeon about surgical treatments for dark circles caused by sagging fat in the lower eyelids—things like the Hamra method, reverse Hamra method, and fat removal...

Actually, the reverse Hamra technique might only be possible until your early 40s, when there's still enough collagen in the lower eyelid!

No wonder—I overheard that if collagen in the lower eyelids decreases, the skin loses its firmness and might not look its best after treatment? As a woman in my 40s, I decided to focus on the lower eyelids and the skin around my eyes for rejuvenation. To boost collagen, I chose the following two products.

 

⭐Rejuran i⭐
⭐Potenza's DDR and Diamond Chip for High Frequency⭐

(This treatment uses two types of needle-free tips.)

I would like to challenge tightening of the lower eyelids by undergoing three courses of this therapy!!

Rejuran Healer

 

Rejuran (Salmon Injection) is an injectable formulation primarily composed of PN (polynucleotides). It is a preparation used for cosmetic purposes, made by highly purifying DNA fragments extracted from salmon DNA.

The official name is Rejuran Healer. By introducing DNA fragments,The action of promoting the repair and regeneration of cells and tissues, as well as the formation of new blood vessels, utilizing one's own wound-healing capabilities.It is said to have effects that aid in repairing abnormal blood vessels and reducing inflammation, and it is also believed to be effective for rosacea.

The key is that this treatment stimulates fibroblasts to produce collagen and elastin, improving skin firmness, tightening, and elasticity. It offers natural rejuvenation beyond mere volume enhancement.is.

Furthermore, it increases vascular endothelial growth factor (VEGF) to promote angiogenesis, offering localized blood flow improvement and helping reduce dark circles caused by congestion around the eyes. Its anti-inflammatory properties aid in repairing acne scars and wounds, mitigating UV damage, and restoring abnormal blood vessels. By balancing sebum and enhancing skin's moisture retention, it refines skin texture. Its multifaceted actions work to give skin a youthful appearance.

 

Rejuran i

 

At BIANCA CLINIC, we tailor our treatments to each patient's concerns, treatment area, and skin condition, utilizing both standard Rejuran and Rejuran i (Rejuran Eye) specifically designed for the eye area.

The standard Rejuran treatment is primarily applied to the entire face, forehead, neck, and décolleté. It is characterized by its multi-purpose effectiveness in addressing a wide range of concerns, including sagging skin, loss of firmness, enlarged pores, nasolabial folds, forehead wrinkles, and acne scars.

Rejuran i is a formulation specifically designed for the eye area. Its low viscosity allows for easy absorption, making it ideal for treating fine lines around the delicate, thin skin of the eyes and dark circles under the eyes.It can also be used around the mouth, where the skin is delicate.

potenza

 

POTENZA is a high-frequency device capable of addressing various skin concerns.RF: Radio FrequencyA multi-platform treatment for the skin.microneedleinsert an ultra-fine needle called,Irradiate high-frequency waves from the needle tipPerforms hemostasis using high-frequency energy while utilizing various specialized tips (see below) to address melasma, acne scars and craters,Addresses various skin concerns such as sagging and fine linesI will do so.

・Liver spots (both cheeks)
Potenza directly applies high-frequency energy to the melanocytes themselves, effectively suppressing the production of melanin that causes melasma.
Through a fundamental approach, it reduces the risk of worsening melasma and vitiligo regardless of skin type.
This new treatment focuses on post-inflammatory hyperpigmentation and enables high-frequency energy at parameters that do not destroy melanocytes.

・Pores・Acne scars・Craters・Redness (Full face)
McCoom, a formulation that uses fine needles to puncture the skin, promotes wound healing in the dermis by emitting high-frequency waves from the needle tips alongside surface wound healing effects. This stimulates the production of collagen and elastin, components essential for beautiful skin. It utilizes a fine-particle biodegradable polymer (PLLA) formulation. When injected subcutaneously, it promotes dermal collagen production, improving pores and acne scars.

・Diamond Tightening (Full Face)
This treatment utilizes the POTENZA Diamond, a non-needle tip device.
This tip enables tightening treatment by delivering uniform energy deep into the tissue through continuous high-frequency irradiation of monopolar and bipolar electrodes in a single shot. It also features minimal burden on the skin, reduced pain, and virtually no downtime.

・Iron (full face)
This treatment uses microneedles to deliver radiofrequency (RF) energy, promoting skin tightening. By applying RF energy to the collagen in the dermis, protein denaturation occurs within the skin, resulting in a lifting effect. Furthermore, the wound healing effect after irradiation promotes collagen production during the repair process of thermal damage. This collagen generation increases skin firmness and elasticity, leading to a more resilient and radiant complexion.

・Fine lines around the eyes (eye area)
Using a needle-free tip, it instantly delivers high-frequency energy to the epidermis, creating micro-sized micro-injuries. This triggers the wound healing response to promote skin resurfacing (skin regeneration and rejuvenation). It is effective for improving skin texture, enhancing skin firmness, and reducing fine lines. Redness and unevenness may appear after treatment but typically subside by the next day.

・Inflamed acne
Using insulated needles, it is possible to deliver high-frequency energy directly to the sebaceous glands without causing inflammation of the epidermis, thereby destroying the sebaceous glands.

 

POTENZA offers a variety of tips tailored to specific treatment objectives.

 

Potenza inserts ultra-fine needles called microneedles into the skin and emits high-frequency energy from the needle tips. In addition to the aforementioned applications, the single-needle device is also expected to be effective for treating syringomas.

Potenza's Key Points
① Deliver the medication to the dermis
Chips equipped with Potenza's unique drug delivery system ensure ingredients penetrate deeply and evenly into the skin. Three synergistic effects are expected: the insertion of microneedles into the skin, the skin regeneration process triggered by radiofrequency heat, and the efficacy of the medication.

② Reduced downtime
Conventional microneedle treatments often caused bleeding and tended to result in longer downtime when targeting deeper skin layers.
However, Potenza reduces bleeding by emitting high-frequency energy from the needle tip, enabling treatment with shorter downtime than conventional methods.

Selecting the appropriate tip for your skin concerns and treatment goals
The Potenza system offers a variety of treatment tips tailored to specific skin concerns and treatment objectives. These include tips with varying needle counts and lengths suited to therapeutic goals, as well as innovative options unavailable in conventional microneedling treatments. Examples include tips with integrated drug delivery systems, tips designed to deliver thermal energy precisely to targeted areas, and tips capable of uniformly affecting all skin layers.
