Most people recover from Bell’s palsy within 2 to 3 weeks, with a full return of facial movements. In about 20 to 30% of cases, the facial nerve is damaged more deeply and needs to regrow. Then the first movements return after 3 weeks to 4 months, and the recovery settles after about 10 to 14 months.
How long your recovery takes depends on how deeply the facial nerve was damaged. Below, we explain the two recovery scenarios, what happens week by week, and when it is worth getting specialist advice. In this article, we use “Bell’s palsy” for any peripheral facial palsy, including facial nerve paralysis with a known cause, as most people do.
Key facts about Bell’s palsy recovery
- Quick recovery (70 to 80% of people): movements return within 2 to 3 weeks, usually without complications.
- Long recovery (20 to 30%): first movements after 3 weeks to 4 months; the result settles after 10 to 14 months.
- The nerve regrows at most 1 mm per day. It needs to grow back about 8 to 10 cm, which is why a long recovery takes months.
- The first sign is not movement. Muscle tone returns first, so the face looks more even at rest.
- Improvement is possible for years. After the recovery settles, complications such as synkinesis can still be reduced with specialized rehabilitation.
The two recovery scenarios
When Bell’s palsy happens, swelling or a reduced blood supply damages the facial nerve in a narrow bone channel behind the ear. The depth of that damage decides which of two scenarios your recovery follows.
| Quick recovery | Long recovery | |
|---|---|---|
| What was damaged | Only the insulation of the nerve (myelin sheath) | The insulation and the nerve fibres themselves |
| How common | 70 to 80% of people | 20 to 30% of people (1 in 4) |
| First signs of recovery | Within the first week | After several weeks |
| First movements | Around day 10 to 15 | Between week 3 and month 4 |
| Full result | By the end of week 3 or 4 | Settles after 10 to 14 months |
| Risk of complications | Low | High (synkinesis, tightness, asymmetry) |

Quick recovery. If the swelling goes down within about 4 to 6 days, only the insulation around the nerve fibres is damaged. Signals cannot pass for a while, which is called a conduction block. The insulation grows back within 1 to 3 weeks, and the movements return in full.
Long recovery. If the damage lasts longer, the nerve fibres die from the point of damage to the face. Your body then regrows them, at most 1 mm per day, over a distance of about 8 to 10 cm. Different branches of the nerve regrow at different speeds, so some movements return weeks before others. This scenario is more common after an infection, such as Ramsay Hunt syndrome.
How do I know which scenario I am in?
In the first days, nobody can tell for sure. No test can measure the depth of the damage right after the onset. The best guide is when the first signs of recovery appear:
- Signs within the first week (tingling, twitching, a less droopy face): you are most likely on the quick path.
- No change at all after 2 to 3 weeks: you are most likely on the long path. This does not mean the nerve is not healing. It means it is regrowing, which takes longer.
To see small changes, take the same set of photos or short videos once a week. Our guide to measuring your recovery at home shows which expressions to record. Read more about the first signs of recovery.
Bell’s palsy recovery stages, week by week
Bell’s palsy recovery stages, week by week
Days 1 to 3: the paralysis develops. The weakness reaches its peak within a few hours to 2 days. See a doctor the same day. Steroids work best when started within 72 hours. Read what to do right away.
Week 1: no visible change. Keep your face warm, protect your eye, do gentle massages and avoid stress. On the quick path, the first sensations and a return of muscle tone may already appear.
Weeks 2 to 3: the quick path ends. If the damage was light, the first movements appear around day 10 to 15 and most others follow within about 10 days. If nothing has changed by the end of week 3, the recovery is most likely long.
Weeks 3 to 12: waiting for the nerve to regrow. On the long path, nothing visible may change for weeks. The face should not get worse. Do not force facial expressions to check for movement: until the nerve reconnects, no effort will move the muscles.
Months 1 to 4: the first movements return. Muscle tone returns first, then small movements of the eye, the mouth corner or the eyebrow. Most remaining movements follow within the next 4 to 8 weeks.
Months 4 to 9: movements keep improving. This is also when complications such as synkinesis and facial tightness tend to appear.
Months 9 to 14: the recovery settles. Changes slow down and the result stabilizes (reaches a plateau). Further improvement after this point usually needs specialized rehabilitation.

What affects how long recovery takes
- How deep the damage is. This is the most important factor, and it is set in the first days.
- How quickly treatment starts. Steroids in the first 72 hours reduce swelling and can limit the damage. Read more about prednisone for Bell’s palsy.
- The cause. Facial palsy caused by a virus or bacterial infection, such as Ramsay Hunt syndrome, usually takes longer, because the swelling lasts until the infection is treated.
- Your general health. The nerve regrows like any other damaged tissue, so it depends on your body’s reserves. Sleep, food and rest all matter. Diabetes and high blood pressure can slow recovery.
- Stress. Panic and despair, and jumping from one “miracle cure” to another, drain the body’s capacity to heal. Read about the role of stress.
- What you do during recovery. Strong facial exercises and electrical stimulation can encourage synkinesis. Gentle massages, warmth and relaxation support the nerve.
When to see a specialist
- No movement at all after 3 to 4 months. This does not mean the palsy is permanent, but the damage was deep and a specialist assessment can help you plan the next months.
- Signs of synkinesis, such as the eye closing when you smile, or the chin dimpling when you blink. It is easier to reduce when it is addressed early.
- Tightness, pain or spasms in the face or neck. Read about facial pains and contractures.
Can Bell’s palsy last for years?
Can Bell’s palsy last for years?
The paralysis itself does not last for years. It ends when the first movements return. What can remain after a long recovery are complications: weakness, asymmetry, synkinesis, tightness. These do not usually go away on their own, but they can be reduced, even many years after the onset. Read more in Is Bell’s palsy permanent?
How we can help
Crystal Touch specializes in the late stages of recovery, when movements have returned but the face has not fully recovered. If you are unsure where you are in your recovery, or your progress has stalled, a video consultation with Dr. Alex Pashov can clarify your situation and what improvement is realistic.
Frequently asked questions
In most people, 2 to 3 weeks. In about 20 to 30% of people, the first movements return after 3 weeks to 4 months, and the recovery settles after about 10 to 14 months.
The first sign is usually a return of muscle tone: the face looks less droopy at rest. You may also feel tingling, twitching or itching. Small movements of the eye or mouth corner follow. See the first signs of recovery.
Only at the very start. The weakness can increase for up to 2 or 3 days until it reaches its peak. After that, it should not get worse. If new symptoms appear later, see your doctor.
Damaged insulation grows back in 1 to 3 weeks. Damaged nerve fibres regrow at most 1 mm per day, so the first movements can take 3 weeks to 4 months to return.
Yes. On the long path, movements keep returning and improving for months after they first appear, and the result settles after about 10 to 14 months.
No. Natural recovery slows down after about a year, but complications such as synkinesis and tightness can still be reduced with specialized rehabilitation, even decades later.
