Thread Lifting for Sagging Cheeks at Age 35: Too Early, and Which Thread Type Should You Choose?
Mor Pun gets this question often: "I'm only 35 — isn't thread lifting too early?" The answer is: not too early at all, because facial structural decline doesn't begin on the day you notice visible sagging — it begins at the cellular level years beforehand.
In the late 30s to age 35, the body's production of Type I and Type III collagen — the key structures supporting skin and underlying tissue — begins declining steadily. At the same time, facial retaining ligaments, which hold cheek tissue in position, begin loosening with age. Together, these two factors cause cheeks to trend toward slight descent, even when many people can't yet see it clearly with the naked eye.
Why Addressing This at 35 Has an Advantage
A point Mor Pun wants to emphasize: thread lifting when cheeks haven't sagged much yet is different from thread lifting when structure has already declined significantly. At age 35, the primary goal usually isn't correcting advanced sagging — it's slowing the aging process and stimulating ongoing new collagen production, to help maintain already-good structure for longer.
Understanding this mechanism matters greatly when choosing a thread type suited to your goal, since different threads have different collagen-stimulating properties.
How Different Thread Types Differ
Three main dissolvable thread types are widely used today: PDO (Polydioxanone), PLLA (Poly-L-Lactic Acid), and PCL (Polycaprolactone) — each with different absorption timeframes and collagen-stimulating mechanisms.
A study published in the Journal of Cosmetic Dermatology in 2021 compared all three thread types in detail, using an animal model. Threads of each type were implanted beneath the skin, with results tracked at 1, 4, and 8 weeks, assessing Type III collagen levels, TGF-β levels, inflammatory cell count, and skin wrinkle area.
Mor Pun wants to walk through these findings in detail, because even though this data comes from an animal model, it offers genuinely interesting mechanistic insight.
What the Study Found
The first finding: at 8 weeks, both original and new PCL threads stimulated significantly more new collagen than PDO and PLLA — with new collagen area increasing by approximately 50% compared to the other two types.
The second finding: new PCL threads worked faster, stimulating more collagen than other thread types starting at just 4 weeks. Researchers suggest this may relate to higher molecular weight, less residual monomer, slower degradation, and longer-lasting structural support — allowing more sustained fibroblast stimulation.
The third finding: new PCL threads showed clearly higher TGF-β levels than PDO and PLLA, particularly at 8 weeks. TGF-β is a key growth factor responsible for stimulating fibroblasts, producing new collagen, and aiding tissue repair.
The final finding: even within the study's short 8-week timeframe, the new PCL group showed approximately 20% reduction in wrinkle area. However, researchers clearly noted that the follow-up period was too short, and further long-term studies are needed to confirm clinical results in humans.
Why PCL Tends to Stimulate Collagen for Longer
Based on approximate absorption timeframes, PDO absorbs within 6-8 months, PLLA within approximately 12 months, while PCL absorbs within approximately 12-18 months. As long as the thread remains in the skin layer, the body continues responding by producing new collagen and supportive tissue. This is one reason PCL is often considered for those wanting longer-term results.
Important Limitations to Understand Before Using This to Inform Decisions
Mor Pun wants to be direct that this study has significant limitations that must always be considered alongside its findings. First, it's an animal study, not human. Second, the sample size was relatively small. Third, follow-up was only 8 weeks — too short to draw long-term conclusions. Fourth, only monofilament thread was used, not covering other thread types used clinically.
Therefore, these findings should be used to understand the working mechanism and potential of each material in principle, rather than concluding broadly that one thread type is superior for every patient. Choosing the appropriate thread type still depends on an individual facial structure assessment, treatment goals, and the judgment of a specialist physician.
Appropriately Considering Thread Lifting for Sagging Cheeks at 35
For those age 35 beginning to notice early signs of cheek descent, considering thread lifting should always start with a thorough facial structure assessment by a physician — not choosing a thread type based on trends or unassessed recommendations. Since goals at this age can vary between individuals, some may want to focus primarily on slowing decline and stimulating collagen, while others may have localized sagging requiring lifting as well.
Closing Summary
Thread lifting for sagging cheeks at age 35 isn't too early, since collagen and facial ligament decline begins before it becomes visible to the naked eye. The study comparing PDO, PLLA, and PCL threads, while an animal study with limitations, offers useful mechanistic information for understanding how each material stimulates collagen and for how long. Choosing the most suitable thread type should always be under the assessment and guidance of a specialist physician who thoroughly understands each individual's facial structure.
