Le Prof. Dr. med. Ivo Buschmann est titulaire de la chaire d'angiologie à la Medizinische Hochschule Brandenburg Theodor Fontane (MHB) et directeur de la clinique universitaire d'angiologie à l'hôpital universitaire de Brandebourg. Il a effectué sa formation médicale à l'Université de Hambourg, a été boursier de la Société Max-Planck à l'Institut Max-Planck de recherche sur le cœur et les poumons, et a occupé des postes de consultant principal à la Charité Universitätsmedizin Berlin Campus Virchow avant d'être nommé titulaire de la chaire à la MHB en 2016.
Le Prof. Buschmann est l'une des principales autorités européennes en arteriogenèse — la croissance et le remodelage des vaisseaux sanguins induits par le flux — avec plus de 150 publications évaluées par des pairs et plusieurs brevets américains et européens sur des dispositifs stimulant la croissance des vaisseaux collatéraux par une thérapie contrôlée du taux de cisaillement. Ses recherches relient la stimulation mécanique et électrique à l'adaptation vasculaire, à la microcirculation et à la perfusion tissulaire.
Les contributions du Prof. Buschmann apportent aux lecteurs de PureLift LAB une perspective en biologie vasculaire qui complète notre expertise clinique, en physiothérapie et en anatomie chirurgicale — expliquant comment la stimulation EMS engage non seulement les muscles faciaux mais aussi la microcirculation qui les alimente, et pourquoi une administration intelligente est aussi importante au niveau du flux sanguin qu'à celui de la contraction musculaire.

Mild asymmetry is normal and usually comes from sleeping position, chewing habits and natural bone differences, and sudden one-sided drooping is a medical emergency rather than a cosmetic question.
This article sets out what to check before you start, such as:
- the emergency test to do before anything else
- why almost every face is asymmetric
- the everyday habits that deepen it
- whether to work one side harder than the other
- when asymmetry warrants a doctor rather than a routine
and many more!
Read the first section before the rest of the article, because one cause of new one-sided drooping needs emergency care within hours.
Key Points:
Sudden one-sided facial drooping, especially with arm weakness or slurred speech, is a stroke symptom and requires emergency services immediately.
Facial nerve conditions including Bell's palsy also cause sudden one-sided weakness and need prompt medical assessment, ideally within seventy-two hours.
Gradual, mild asymmetry that has been there for years is normal and present in almost everyone.
Sleeping on one side, chewing predominantly on one side and natural bone differences all contribute to the everyday kind.
Treating one side harder with a device is a bad idea, because you cannot measure what you are doing and you can easily overshoot.
Read this first, the emergency test
If one side of your face has drooped suddenly, within minutes or hours, stop reading and check three things.
The three-step check
Face. Ask the person to smile. Does one side of the mouth fail to lift.
Arms. Ask them to raise both arms and hold them up. Does one drift downward.
Speech. Ask them to repeat a simple sentence. Is it slurred or strange.
If any of those three is present, call emergency services immediately. Time is the single biggest factor in stroke outcomes and treatment windows are measured in hours.
Facial nerve conditions
Sudden one-sided facial weakness without arm or speech involvement can be Bell's palsy, an inflammation of the facial nerve.
It is not a stroke and is usually temporary, and it still needs assessment quickly because treatment started within seventy-two hours improves outcomes.
Either way, sudden facial weakness is a same-day medical matter and not something to adjust your skincare routine around.
Anyone with a history of a facial nerve condition should speak to a neurologist before using any stimulation device, which we set out in our article on nerve safety.
Why almost every face is asymmetric
Symmetry is the exception rather than the rule. If you mirror either half of your own face in a photo editor, both results look wrong to you, which tells you how asymmetric the original is.
Bone
The two halves of the facial skeleton develop separately and rarely end up identical, so eye socket height, cheekbone projection and jaw length usually differ slightly.
Those differences are set long before adulthood and no routine changes them.
They also become more visible with age, because the soft tissue that used to disguise them thins.
Soft tissue
Fat pads do not shrink at identical rates on both sides, so volume loss is rarely even.
Skin on the side that has had more sun exposure, often the driver's side in countries where people commute, ages faster and sags earlier.
The result is that a difference which was always there becomes noticeable in a particular decade.
The everyday habits that deepen it
Sleeping predominantly on one side presses the face into a pillow for hours a night, which over years compresses tissue and deepens creases on that side.
Chewing mostly on one side builds the masseter on that side, which can widen the lower face asymmetrically.
Carrying a bag on one shoulder, holding a phone against one ear, and resting a chin on one hand all contribute in smaller ways.
Sun exposure is the most underrated of the group, and the difference between the two sides of the face in people who drive a great deal is well documented in dermatology.
Should you work one side harder
No, and this is the main practical question people ask.
Why not
You cannot measure what you are delivering to one side versus the other. Contact quality, serum thickness, probe pressure and skin resistance all vary between sessions.
Muscle responds to load, so if you overshoot on the weaker side you can create a new asymmetry in the opposite direction.
The underlying cause in most cases is bone and fat rather than muscle, so you are adding muscle to compensate for a structural difference, which does not work the way people hope.
What to do instead
Work both sides identically, three minutes each, which is the maximum on all our models anyway.
If one side genuinely feels weaker or responds less, that is worth mentioning to a doctor rather than compensating for at home.
Address the habits instead, since changing your sleeping position and your chewing side costs nothing and addresses a real cause.
The full session structure is in our step by step guide.
What actually helps the cosmetic kind
Sleeping on your back, which removes the nightly compression and is the single most effective free change available.
A silk or satin pillowcase if you cannot change position, which reduces friction without addressing the pressure.
Daily sunscreen on both sides, with attention to the side that gets more exposure in your car.
Filler placed by an injector who assesses both sides, which is the standard correction for a volume difference and is more precise than anything done at home.
A device used evenly, which improves overall tone and makes both sides look better without changing their relationship to each other.
When asymmetry warrants a doctor
Any sudden onset, which is covered in the first section and is the most important line in this article.
Asymmetry that is getting worse month by month rather than staying stable.
Asymmetry accompanied by pain, numbness, changes in hearing or taste, or difficulty closing one eye.
A visible difference in how the two sides move rather than how they sit, since movement differences point to nerve rather than structure.
New asymmetry after dental work, facial surgery or injectables, which should go back to whoever performed the procedure.
The honest summary
Mild, longstanding asymmetry is normal, extremely common, and noticed far more by you than by anyone else.
A device will not correct it and will improve overall tone on both sides, which is a reasonable thing to want.
Treating one side harder is the one approach that can genuinely make things worse, which is why this article exists.
Sudden asymmetry is not a cosmetic issue at all, and if that is why you are reading this, the first section is the only part that matters.
Frequently asked questions
Is it normal for one side of your face to sag more
Yes. Almost all faces are asymmetric, driven by natural bone differences, uneven fat loss, sleeping position and uneven sun exposure. Longstanding mild asymmetry is normal.
Can sleeping on one side cause facial sagging
Sleeping on one side compresses the face for hours each night, and over years this can deepen creases and contribute to an uneven appearance. Sleeping on your back avoids it.
Should I use microcurrent on only one side of my face
No. You cannot control the dose precisely enough to even out a difference, and overshooting creates a new asymmetry. Work both sides identically.
When is facial asymmetry a medical emergency
When it appears suddenly, especially with arm weakness or slurred speech. That combination suggests a stroke and requires emergency services immediately.
Can Botox fix facial asymmetry
An experienced injector can sometimes balance asymmetric muscle activity with toxin, and volume differences are usually addressed with filler instead. Both are clinic procedures requiring assessment of both sides.
