Low-level electrical current devices studied for facial muscle stimulation and skin lifting effects.
The Idea
Microcurrent devices apply low-level electrical currents to stimulate facial muscles and potentially lift the skin. This proposed mechanism of action is based on the idea that muscle contractions can stimulate collagen production and improve skin elasticity. However, the exact mechanisms and efficacy of microcurrent devices are not yet fully understood.
What the Evidence Shows
Research on microcurrent devices is primarily based on small-scale, short-term studies, including in vitro experiments, animal studies, and human clinical trials. These studies indicate that microcurrent stimulation can increase collagen production, improve skin elasticity, and reduce fine lines and wrinkles. However, the evidence is limited by small sample sizes, short follow-up periods, and a lack of long-term studies. Additionally, most studies were conducted on in-clinic devices with high-powered settings, which may not be comparable to at-home consumer devices.
Verdict
The current state of evidence suggests that microcurrent devices may have some benefits for facial skin, but more research is needed to fully understand their efficacy and potential long-term effects. In-clinic devices have been used professionally for skin lifting and rejuvenation, but their use in at-home settings is largely anecdotal and not well-studied.

Microcurrent Radiofrequency May Help Improve Periorbital Skin Laxity
Researchers studied a small group of patients with facial skin laxity and photodamage to see if a non-invasive treatment using microcurrent radiofrequency could improve their skin. The treatment, called Plasma IQ, produced some positive results, including improved skin elasticity and increased distance between the upper eyelid margin and fold. However, more research is needed to confirm these findings.
Why it matters: This study may help skincare professionals and patients understand the potential benefits and limitations of non-invasive treatments for periorbital skin rejuvenation.
This study had a small sample size of 30 patients and only looked at short-term results up to 90 days post-treatment.

Noninvasive Treatment May Help Improve Midface Appearance
A small study looked at a new noninvasive treatment that combines radiofrequency and electrical stimulation to see if it could improve the appearance of the midface. Researchers found that this treatment may help increase muscle thickness, improve skin displacement, and boost facial volume. However, more research is needed to confirm these findings.
Why it matters: This study may help skincare professionals understand new noninvasive treatments for facial rejuvenation.
This study had a small sample size of 37 participants and was not a randomized controlled trial. Further research is needed to confirm these results and assess long-term effects.

New Noninvasive Treatment May Help Improve Facial Skin Laxity and Quality
Researchers studied a new noninvasive treatment that combines radiofrequency and high-intensity facial electrical stimulation to improve facial skin laxity and quality in Asian subjects. The treatment was applied for four weeks and assessments were conducted at various time points. The study found significant improvements in facial lifting, skin firmness, and skin texture.
Why it matters: This study may contribute to the development of new noninvasive treatments for facial rejuvenation, which could be beneficial for individuals seeking to improve their skin appearance.
The study had a small sample size of 15 participants and was conducted over a relatively short period of time.
