EMS and microcurrent both use electrical stimulation and can be used as part of a facial toning routine. By stimulating the tissues and muscles beneath the skin, both technologies are commonly associated with improving the appearance of facial definition, temporary puffiness, and age-related loss of tone.
The difference is mainly in how strongly they stimulate the muscles.
EMS is designed to produce more noticeable muscle activation and may create visible or palpable contractions during treatment. This makes it more focused on actively engaging facial muscles and supporting improvements in muscle tone and facial contours over time.
Microcurrent works with a much lower level of electrical current. The stimulation is generally gentler and usually does not produce obvious muscle contractions, although it is still used to support facial toning and a more lifted or defined appearance.
So, the two technologies are not completely different in purpose. Both can contribute to facial toning, but EMS places greater emphasis on active muscle stimulation, while microcurrent offers a lower-intensity approach for users who prefer a gentler treatment experience.
| EMS | Microcurrent | |
| Main focus | Facial muscle stimulation | Low-level electrical stimulation |
| Muscle contraction | Usually noticeable | Typically no visible contraction |
| Sensation | Tingling or muscle movement | Mild or barely noticeable |
| Best suited for | Tone and facial definition | Gentle facial care |
| Treatment experience | More active | More subtle |
The Biggest Difference Is How Strongly the Current Stimulates the Muscles
The easiest way to tell EMS and microcurrent apart is by paying attention to what your facial muscles actually do during treatment.
With EMS, the current is delivered at a level intended to activate the motor nerves. That activation causes the targeted muscles to contract, so depending on the treatment intensity. You may feel a distinct tightening sensation or even see small movements in the face. Read the EMS research review
Microcurrent works with a much lower electrical current, typically in the microamp range. The treatment is generally more subtle and is not typically designed to produce the obvious muscle contractions associated with motor-level stimulation. Read the microcurrent research review
Both technologies are used in facial devices designed for toning, but the treatment experience can feel quite different. Facial NMES, for example, uses stimulation intended to produce an actual muscle response, whereas microcurrent is generally intended to provide a lower-intensity form of electrical stimulation.
What Does EMS Do for the Face?
EMS is most relevant when facial muscle activation is part of the goal.
When people talk about facial aging, they often focus only on the skin. But a softer facial contour can involve more than changes at the skin's surface. The appearance of the cheeks, jawline, and lower face is also influenced by the underlying soft tissue and facial muscles.
This is where EMS takes a different approach from many skin-focused treatments, EMS may be relevant to people concerned about:
- A softer-looking jawline
- Less defined cheeks
- Reduced facial muscle tone
- A less structured or less defined facial contour
In one randomized controlled trial involving 108 women, participants used a facial NMES device for 12 weeks. The researchers measured the thickness of the zygomaticus major muscle and found an increase in the NMES group compared with baseline and the control group. Participants using the device also reported improvements in facial firmness, tone, and lift. Read the randomized controlled trial
Take the JOVS 6D Laser & EMS Mask as an Example
The JOVS 6D Laser & EMS Anti-Aging Therapy Mask uses a 10-electrode EMS system as the muscle-focused part of its treatment: positioned across the face to deliver EMS stimulation to key muscle groups involved in facial movement and contour, including the temporalis, zygomaticus, masseter, and buccinator muscles.
Rather than concentrating on one small area, the system is designed to provide broader EMS coverage across the upper face, cheeks, and lower-face region. Read How EMS Work on Facial Muscle
JOVS 6D Laser and EMS Mask also combines EMS with low level laser light therapy. This means the treatment is not limited to muscle stimulation alone: the EMS component focuses on facial muscle activation and contour support, while the laser-based treatment adds a separate skin-rejuvenation element to the same routine.
Key features of JOVS 6D Laser and EMS Mask
10-Electrode Full-Face EMS
Targets key facial muscle groups across the forehead, cheeks, and lower face for broader muscle stimulation and contour-focused treatment.
Active Muscle Stimulation
Uses adjustable EMS intensity to create a noticeable muscle response, making it a more active treatment option than lower-level electrical stimulation.
Laser + EMS in One Treatment
Combines muscle-focused EMS with multi-wavelength laser light therapy, addressing facial contours and visible skin aging in the same routine.
Multi-Wavelength Laser Skin Care
Adds 660 nm, 850 nm, 940 nm, and 1064 nm laser wavelengths, along with broader-spectrum light coverage, to support skin firmness, texture, and overall rejuvenation.
Those concerns do not necessarily come from the same underlying changes, so a device combining different technologies may offer a broader treatment approach.
What Does Microcurrent Do for the Face?
Microcurrent uses a much lower electrical current than EMS.
The treatment generally does not produce the visible or palpable muscle contractions associated with EMS.
This creates a different treatment experience.
For many users, microcurrent may appeal because the stimulation is subtle and involves little or no visible facial movement.
Microcurrent and EMS can therefore overlap in the broader category of electrical facial devices, but they should not automatically be expected to produce the same type of neuromuscular response.
If noticeable facial muscle activation is the main goal, EMS is the more direct option.
If a person prefers a lower-intensity electrical treatment with little or no visible muscle movement, microcurrent may be a more suitable experience.
EMS vs Microcurrent: Which One Makes More Sense?
For Facial Muscle Activation and Definition
EMS is the more direct option. It is designed to stimulate the neuromuscular system and create muscle activation, making it a more relevant choice when facial muscle stimulation and definition are the main focus.
For a Gentler Treatment Experience
Microcurrent may be a better fit.The current is much lower, and treatment usually involves little or no visible muscle movement.
Facial Sagging Is Not Only a Muscle Problem
Facial sagging and changes in facial definition do not come from muscle changes alone.
As the face ages, visible changes can involve multiple layers, including the skin, facial muscles, soft tissue, and facial volume. A softer contour or less defined appearance may therefore have more than one underlying cause.

For Softer Contours and Fine Lines
It may make sense to look beyond electrical stimulation alone.
A softer facial contour and fine lines do not necessarily come from the same underlying changes. When both skin-related and muscle-related concerns are part of the picture, a combination device may offer a broader approach.
The JOVS 6D Laser & EMS Mask combines EMS for facial muscle stimulation with laser-based light therapy for skin-focused care, allowing both treatment focuses to be included in the same routine.
Conlusion
EMS is the more direct option for active facial muscle stimulation, while microcurrent offers a gentler, lower-intensity treatment experience with little or no visible muscle movement.
Because facial sagging can involve more than muscle changes, a combination approach may make sense when both facial contours and visible skin aging are concerns. In that case, combining EMS for muscle stimulation with laser-based therapy for skin-focused care can provide a broader treatment approach.
