For tear troughs and sunken eyes, we recommend the new hyaluronic acid filler ”Teosyal”!
A dual-specialty doctor with a background in plastic surgery, bridging cosmetic surgery and ophthalmology. At the university hospital, he performed numerous high-difficulty cases, primarily focusing on eye and facial bone surgeries, cultivating precise techniques grounded in anatomy. He prioritizes achieving both aesthetic beauty and functional safety, offering customized treatments around the eyes that incorporate ophthalmological expertise. He actively utilizes not only incisional surgery but also non-invasive procedures like hyaluronic acid injections. By carefully assessing each individual's condition and unique appeal, he provides bespoke treatments that guide patients toward naturally harmonious, well-defined eyes.
Hello, I'm Ryutaro Natsume, an image designer and cosmetic surgeon.

What defines natural, elegant eyes that don't look surgically altered?
Of course, causes can include an unnatural double eyelid width or overly droopy eyes.
However, this time we will consider it from a higher perspective.
The lack of coordination between overall facial expressions and eye movements creates an unnatural appearance around the eyes.There may be cases.
◯Botox overdose, with some areas affected and others unaffected
◯ Unnatural amount of tear troughs, noticeable discomfort when smiling
My sunken eyes have healed, but every time I blink, the hyaluronic acid seems to move around and look lumpy.
etc.

Eye area treatments are meticulously administered by focusing on the injection layer and dosage (Botox at 0.5 units, hyaluronic acid at 0.01cc units).

"Get a fresh, polished look with tear trough hyaluronic acid!"
Not only that, but we are also pursuing better formulations.
What we are actively recommending is,The Teosyal RHA series!
① Low risk of allergies
Hyaluronic acid allergies (swelling, redness, lumps, etc.) are said to occur more frequently with higher concentrations of BDDE, a hyaluronic acid crosslinking agent used to enhance durability.
Teosyal RHA utilizes specialized technology to maintain results for over a year while keeping BDDE content low, resulting in a reduced risk of allergic reactions.
For the delicate eye area, use safe formulations.
② Natural eye movement
Teosyal RHA is the latest hyaluronic acid featuring patented technology that provides superior elasticity and flexibility.
”Known as ”dynamic aesthetics," it stretches and contracts with facial movements, blending naturally without losing its shape.
It offers significant benefits, particularly around the eyes where movement is substantial.
