Facial Thread Lifting: From Principles to Recovery — A Guide to Downtime and Home Care

What Is Facial Thread Lifting?

Facial thread lifting is known to involve inserting biodegradable medical threads made of PDO, PLLA, or PCL into the lower layers of the skin (from the lower dermis to the subcutaneous tissue). It is designed to support sagging tissue with minimal incisions, or to induce a tissue response around the thread.

According to international academic reviews, the primary mechanism of action of these threads is to stimulate fibroblasts, inducing collagen and elastin production, and as the skin tissue is remodeled during this process, a secondary tensioning effect may also occur. Some threads have barbed structures along their sides, which are also reported to provide a direct physical pulling effect on tissue upon insertion.

In other words, it is more accurate to understand thread lifting not simply as a procedure where the thread pulls the skin, but as one where two mechanisms work together: the physical support of the thread itself, and the collagen production response the body generates by recognizing the thread as a foreign material.

Mechanism of Action — Collagen Remodeling and Tissue Response

PDO threads are reported to trigger a selective inflammatory response after insertion, which is thought to promote collagen production and tissue contraction. Rather than the commonly used term 'remodeling,' the expressions 'collagen remodeling' or 'collagen restructuring' are considered closer to the actual mechanism.

The absorption period in the body also varies depending on the type of thread. PDO threads are reported to be absorbed within approximately 6 to 8 months, while PLLA and PCL type threads are known to remain in the body for about 12 to 18 months. Even after the thread is absorbed, the induced collagen structure may remain for a certain period, but the duration and perceived degree of this effect are reported to vary between individuals.

One randomized clinical trial confirmed significant changes in tissue position at 20 and 60 days after thread insertion, but it also noted that further research is needed on the long-term collagen-stimulating effect, indicating that some aspects remain unclear.

Effects, Progression, and Limitations

The combined use of hyaluronic acid filler and PDO threads has drawn attention as an approach that addresses both midface volume and sagging, particularly in Asian patients, and a study following Korean subjects for 24 months has also been reported. However, whether and how such combined procedures should be performed depends on individual skin conditions, so this should be determined through consultation with a specialist.

Some researchers report that while thread lifting shows noticeable improvement in the early stages after the procedure, its long-term results may not be as pronounced as those of surgical facelifts. Thread lifting is mentioned as having the relative advantage of minimal incisions and minimal downtime, but this does not mean it can be definitively considered a replacement for surgical methods.

The degree of effect, duration, and satisfaction vary greatly between individuals depending on factors such as skin condition, age, and degree of sagging, so it is recommended to thoroughly consult with a specialist when setting expectations and deciding on a procedure method.

Downtime and Side Effects — The Facts

Bruising, swelling, and a sensation of tightness are commonly reported immediately after the procedure, and most of these are known not to lead to long-term complications.

According to a meta-analysis combining 26 studies published between 2024 and 2026, the most common complication was swelling (pooled incidence of about 35%), followed by skin dimpling (about 10%), paresthesia (about 6%), thread visibility or palpability (about 4%), infection (about 2%), and thread extrusion (about 2%).

Although rare, serious complications suggestive of nerve damage, such as deep infection or persistent paresthesia, are also included, and broader literature has reported adverse events such as facial nerve branch injury, parotid duct injury, and granuloma formation. As these serious cases are noted to be particularly associated with non-absorbable threads, it is necessary to thoroughly check the type of thread used and the practitioner's level of expertise beforehand.

Post-Procedure Recovery Care — Why Soothing and Moisturizing Matter

The area where the thread was inserted may go through a period of temporary swelling and sensitivity. During this time, when the skin barrier is weakened, the skin may react more sensitively to external stimuli, so caring for the skin with low-irritant, soothing ingredients and replenishing hydration and moisture can help support the recovery process.

That said, home care should be understood as part of everyday skin condition management, not as a way to treat side effects of the procedure or to guarantee recovery. If abnormal symptoms persist or worsen, you should be sure to contact the medical institution where the procedure was performed.

Home Care Matters for Post-Procedure Recovery

During the recovery period, when the treated area tends to be sensitive, a routine that combines gentle soothing with deep hydration care may be helpful. ABJU Cream is designed as a 2-step routine with post-procedure care in mind: STEP 1 Ultra Cera-Rich aims to soothe and support the skin barrier for skin that easily feels redness and irritation right after the procedure, while STEP 2 Hydro Re-Boosting can help manage skin condition by replenishing deep hydration during the recovery period that follows. However, this is intended as a supplementary part of everyday skin care and does not imply a treatment effect for procedure-related side effects.
