Biography

Zhang Tianxiuping: Works at Shanghai Tianrui Medical Aesthetic Hospital, Technical Guidance Physician for East Japan, and Director of the Toyama Clinic. Philosophy: Focused on creating Japanese-style, natural "born-with" double eyelids that match the facial features. Specializes in non-invasive internal fixation suture double-eyelid surgery and regularly sees patients in Shanghai every month.

Dr. Zhang Tianxiuping's “non-invasive internal fixation double eyelid”, officially named the MUKIZU Japanese Internal Fixation Method (non-incisional) or Natural Adhesion Suture Method, is his improved high-end suture technique. Its core is deep fixation from inside the eyelid to achieve nearly scarless, long-lasting, natural double eyelids.

Technical Principles (Core Innovations)
Access site: Instead of inserting needles through the skin surface, specially designed sutures are passed through the inner side of the eyelid (conjunctival surface).
Fixation method: The threads are buried deeply between the orbicularis oculi muscle and the tarsal plate/levator aponeurosis, forming a deep, multi-point, circular internal fixation.
Healing mechanism: Rather than relying on forceful traction from the threads, it guides natural tissue adhesion and healing to form a fold that conforms to physiological structure.

Technical Features and Advantages
Truly non-invasive, no trace when the eyes are closed
No incision, no needle holes, and no suture removal on the skin surface.
When the eyes are closed, no artificial traces are visible, closely resembling naturally occurring double eyelids.
High stability, less likely to loosen
Traditional suture methods fix only the superficial skin and tend to loosen; this procedure anchors deeply and has stronger resistance to tension.
Suitable for hidden double eyelids and mild puffy eyes, addressing the tendency of traditional suture methods to become shallow or revert to hidden double eyelids.
Extremely short recovery period
Minimal trauma, mild swelling, and little bruising.
Swelling generally subsides substantially within 3-5 days, and normal social activities can resume within 1 week.
Japanese natural aesthetic
Focuses on narrow double eyelids, parallel fan-shaped folds, and opening fan-shaped folds, with soft lines and a strong "born-with" look.
Preserves the original expression of the eyes, without exaggeration or an artificial look.

Suitable Candidates
Individuals with monolids or hidden double eyelids who wish to improve their eye shape.
Individuals with relatively thin eyelids and mild puffy eyes (with little fat).
Young individuals without loose skin.
Individuals who are afraid of surgery and scarring and seek natural results and rapid recovery.
Individuals with slight asymmetry in eye shape who need minor adjustment.
