Who Is Not a Good Candidate for PDO Threads

PDO threads tend to disappoint, or carry more risk, in people with very heavy or very thin skin, significant sagging, active infection, certain autoimmune or healing problems, a tendency to keloid scarring, or expectations of a surgical-type result. For these people, another treatment, a referral or simply no treatment is often the better choice. Knowing this before a procedure saves time, cost and frustration.

Why candidate selection matters so much with threads

Threads depend on two things working together: the barbs or mesh gripping soft tissue, and the body responding with a mild healing reaction as the material dissolves. If the tissue is too heavy to hold, too thin to hide the threads, or unable to heal normally, neither part works well. Because results are modest even in good candidates, small mismatches can leave someone with little benefit and a recovery period for nothing.

A thorough consultation should therefore be as willing to say "not for you" as "let's proceed."

Candidacy is usually decided by looking at several things together: how your skin looks and feels when gently lifted, how much of the change comes from volume loss rather than descent, your medical history and medicines, and what you are hoping to see in the mirror. One factor on its own rarely settles the question, but a few together often point clearly in one direction. The sections below cover the most common reasons threads are not recommended.

Skin and tissue factors

Very heavy skin or a full lower face

Thick, heavy skin and substantial fat in the jowls or cheeks place a lot of weight on each thread. The barbs may hold for a short time and then slip, so the lift fades quickly. In some cases, the weight can contribute to dimpling along the thread path. Other approaches, such as addressing volume and fat distribution, or a surgical opinion, are often more realistic.

Very thin or fragile skin

At the other end, very thin skin offers little cover. Threads are more likely to be seen as faint lines, felt as ridges, or work their way to the surface. Thin skin is common in older adults, people with significant sun damage and those who have used topical or oral steroids for long periods.

Significant laxity

Threads cannot remove skin. When there is a lot of loose, hanging skin in the neck or jowls, repositioning it a few millimetres does not produce a visible change, and any lift is short-lived. A facelift or necklift consultation is often more useful. Our comparison of PDO threads and filler also explains where lifting is and is not the right goal.

Medical reasons to avoid or postpone threads

Some conditions make threads unsafe at that moment or require input from your physician first:

• Active infection in or near the area, including cold sores, acne flares, dental abscesses or skin infections
• Autoimmune and connective tissue diseases, such as lupus, scleroderma or active inflammatory conditions, which may change how tissue heals or reacts to foreign material
• Poorly controlled diabetes, which raises infection risk and slows healing
• Bleeding disorders or blood-thinning medicines, which increase bruising and need planning
• Immune-suppressing treatment, including chemotherapy or medicines given after an organ transplant; check with your treating physician or oncologist
• Pregnancy and breastfeeding, when elective procedures are generally postponed
• Recent facial surgery or dental work that has not fully healed
• Permanent fillers or facial implants in the treatment area

Never stop or change a prescribed medicine to make a thread procedure possible. Discuss it with the doctor who manages that medicine first.

Scarring and healing tendencies

People who form keloids, raised scars that grow beyond the original wound, may develop them at thread entry points. Even small punctures can trigger a keloid in someone prone to them. A history of unusual reactions to stitches or previous threads is also important to mention. Smoking and vaping reduce blood flow to the skin and can slow healing and shorten results, so they are worth discussing honestly.

Expectations and timing

Medical history is not the only thing that decides candidacy. Threads may not be a good fit if you:

• Hope for a result comparable to a surgical facelift
• Want a permanent change rather than one that fades over months
• Have an event soon and cannot allow time for swelling, bruising and possible adjustments
• Feel pressured by someone else to have treatment
• Find yourself focused on very small details that others do not notice, which may be worth discussing with your family doctor

Some people simply have faces that are ageing well with skincare and sun protection alone. That is a perfectly reasonable place to be.

What may suit you instead

Depending on your concern, alternatives might include hyaluronic acid filler for volume loss, neuromodulator for muscle-related lines and bands, laser or other energy-based treatments for texture and mild tightening, medical-grade skincare, or a referral to a facial plastic surgeon. Sometimes a combination is discussed; our article on combining threads with filler and neuromodulator explains how that can work for those who are suitable.

Risks if threads are used in the wrong situation

In a poor candidate, the usual thread risks, including visible threads, extrusion, dimpling, asymmetry, infection and prolonged discomfort, tend to be more likely or more noticeable. A disappointing result can also mean paying for a procedure and recovery without meaningful benefit. These are the main reasons careful selection matters.

Frequently asked questions

I have an autoimmune condition that is in remission. Can I have threads?

Possibly, but it needs individual review and often a conversation with your treating physician. Remission does not automatically make it suitable.

Am I too old for threads?

Age alone is not the deciding factor. Skin thickness, the amount of laxity and general health matter more.

If I am not a candidate now, could I be later?

Sometimes. Once an infection clears, a pregnancy ends or a medical condition is better controlled, candidacy can be reassessed.

An honest assessment first

Being told threads are not right for you is useful information, not a setback. A consultation with HealthPark Medical Aesthetics can review your skin, health and goals and explain which options, if any, are likely to help.
