The role of fishbone thread carving

Fishbone thread carving is a minimally invasive cosmetic technique that uses absorbable sutures implanted into subcutaneous tissue to achieve facial lifting. It is mainly used to improve facial sagging, nasolabial folds, and blurred mandibular margins. Its mechanism of action includes immediate physical lifting, stimulation of collagen regeneration, and long-term tissue reduction.

1. Immediate physical lifting

The bidirectional barbed structure on the surface of fishbone thread can hook subcutaneous tissue and achieve immediate lifting effect through wire tension. During surgery, the thread body is implanted in a mesh like pattern between the dermis and fascia layers, which can effectively improve problems such as sagging of the middle and lower surfaces and collapse of the apple muscle. Immediately after surgery, the facial contour can be seen to have tightened, but it needs to be fixed with an elastic mask to prevent displacement.

2. Stimulating collagen regeneration

The material used in the wire will gradually degrade, continuously stimulating fibroblast proliferation and promoting the synthesis of type I and type III collagen. This biological stimulation can last for 6-12 months and can improve skin texture, increase dermis thickness, and assist in improving enlarged pores and static fine lines.

3. Long term tissue reduction

As the thread degrades, newly formed collagen fibers will form a fibrous network scaffold along the implantation trajectory, achieving biological remodeling of tissue structure. For patients with mild skin laxity, a single treatment can maintain the effect for 1-2 years. It should be noted that multiple implants may increase the risk of wire slippage, and it is recommended to perform wire replacement at intervals of at least 8 months.

4. Minimally invasive injury repair

Compared to traditional facelift surgery, thread cutting only requires a needle sized incision, and tissue resection is replaced by thread traction force. However, there may be temporary bruising and swelling after surgery, and vigorous exercise should be avoided to prevent displacement of the defense material. The specially designed angle of the fishbone thread can reduce cutting damage, but there may still be complications such as local hematoma and thread head exposure.

5. Indication Control

This technique is more suitable for people aged 30-45 with mild to moderate skin laxity, and has limited improvement on severe mandibular bags and neck wrinkles. Contraindications include coagulation dysfunction and active autoimmune diseases. Combined radiofrequency or ultrasonic knife treatment can prolong the maintenance time, but it requires staged operations with an interval of more than one month.

After surgery, the wound should be kept dry for 3 days, exaggerated facial expressions and movements should be avoided for 1 week, and spicy and stimulating foods should be avoided for 1 month. It is recommended to elevate the pillow during sleep to reduce edema, and regularly follow up to observe the absorption of wires. Daily sun protection care should be strengthened, and skincare products containing peptides and vitamin C can assist in maintaining the effect. If there is persistent redness, swelling or exposed knots, seek medical attention promptly.
