In short. Tightness, tenderness, numbness and odd sensations after suspension threads: which findings settle on their own, and which need reporting rather than watching.
Key points
- Tightness and tenderness usually settle over three to four weeks.
- Numbness and odd sensations often take longer, sometimes a few months, and usually improve gradually rather than all at once.
- Being able to feel a thread under the skin is common early and becomes less noticeable as the tissue accommodates.
Threads are placed through tissue that is full of small sensory nerves, and almost every patient notices something in the weeks afterwards. Most of what they notice is ordinary. A smaller part is not, and the difference is worth setting out plainly.
What ordinary healing feels like
Tightness and a pulled feeling are expected from the first day, because that is literally what has been done. Tenderness on pressure follows, worst over the first week and fading over the next three or four. Aching when the face is used, and discomfort when lying on the treated side, are both normal and both improve steadily.
Altered sensation is also common. A patch of numbness, a feeling of pins and needles, or an area that feels odd to touch can appear along the direction of pull. This happens because a thread can irritate a small sensory nerve as it passes, or because the tissue reaction around it presses on one. Ordinary numbness of this kind narrows over weeks rather than appearing suddenly.
What usually resolves, and on what sort of timetable
Tightness and tenderness usually settle over three to four weeks. Numbness and odd sensations often take longer, sometimes a few months, and usually improve gradually rather than all at once. Being able to feel a thread under the skin is common early and becomes less noticeable as the tissue accommodates.
What is not ordinary
Pain that is worsening after the first week is the single most useful thing to notice. Ordinary healing improves; anything that is getting worse is going in the wrong direction. Sharp or shooting pain, pain that wakes you at night, and pain accompanied by redness, warmth or discharge all point away from ordinary healing.
Numbness that spreads, or that is unchanged after a month, is a finding rather than a nuisance. So is a sudden change in how part of the face moves, which is uncommon but should be reported immediately rather than watched. The direction of change matters more than the level of it.
Why the sensation is hard to judge yourself
A patient is a poor judge of her own sensation, because the change is gradual and because the treated area is compared with itself rather than anything else. A patch of numbness that feels unchanged over a month may have narrowed a good deal. That is why a review compares a photograph rather than a memory.
Report rather than wait
- Pain that is worse in the second week than it was in the first.
- Numbness that is spreading, or that has not changed after four weeks.
- A thread that has broken the skin, or redness and discharge at an entry point.
The practical point is that none of these findings requires you to judge whether something is serious. The judgement belongs to the clinician who placed the thread. Reporting an odd sensation early costs an appointment; waiting three months to mention it costs the window in which it would have been easiest to assess.
Frequently asked questions
Is numbness after threads normal?
A patch of numbness or altered feeling is a known early finding, because a thread can irritate a sensory nerve as it is placed or as the tissue reacts around it. Most of these settle over weeks. Numbness that is spreading, or that is unchanged after a month, needs to be looked at.
How long should tenderness last?
Tenderness is usually worst in the first week and fades over the following three to four, with the treated zone remaining sensitive to firm pressure for a little longer. Pain that is getting worse after the first week rather than better is not part of the ordinary course.
What kind of pain means I should call rather than wait?
Sharp or shooting pain, pain with spreading redness or warmth, pain with a discharge, or pain that wakes you at night. Each of those suggests something other than ordinary healing, and all of them should be reported rather than observed at home.
Risks & Limitations
- A thread changes position, not laxity. It removes no skin, tightens no skin, and the change is temporary.
- The jawline and the neck are the zones where the result is lost soonest, because the load there is greatest.
- A thread can be felt, can pucker the skin, and can work towards the surface, which carries an infection risk.
- An uneven or widened appearance is a known possible result, and further threads rarely correct it.
When to Seek Care
- Difficulty breathing or chest pain: seek emergency care immediately.
- Fever, or spreading redness, warmth or discharge at a thread entry point.
- A thread end that has broken the skin, or a spot that keeps crusting or weeping.
- Numbness that is spreading, or pain that is worsening rather than settling.
