What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to evaluate the safety and effectiveness of a treatment called fractional radiofrequency for individuals with moderate to severe acne. The triLift/Legend Pro+ Fractional RF System will treat only one side of the face, with results compared to the untreated side. Individuals with moderate to severe acne who are currently on tetracycline antibiotics may qualify. Participants must not use other acne medications and should have a similar acne condition on both sides of their face. As an unphased trial, this study provides a unique opportunity to explore a new treatment option for acne.

Will I have to stop taking my current medications?

You can continue taking tetracycline antibiotics for your acne, but you need to stop using other oral anti-acne medications for 6 months and topical anti-acne medications for 1 month before starting the trial.

What prior data suggests that the triLift/Legend Pro+ Fractional RF System is safe for treating acne?

Studies have shown that the triLift/Legend Pro+ Fractional RF System is generally well-tolerated. Research indicates that while skin redness commonly occurs after treatment, it usually appears immediately and lasts up to 10 hours. Importantly, no reports indicated worsening skin texture or new scar formation. The system has been used safely to improve skin conditions such as wrinkles and acne scars. Treatments did not cause bleeding, enhancing its safety profile. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the triLift/Legend Pro+ Fractional RF System for treating acne because it uses radiofrequency energy, a novel approach compared to traditional treatments like topical and oral antibiotics, retinoids, and benzoyl peroxide. This system delivers targeted heat to the skin, potentially reducing inflammation and acne-causing bacteria without the side effects often associated with medication-based therapies. Additionally, the combination of radiofrequency with fractional technology may enhance skin texture and promote collagen production, offering benefits beyond acne reduction, such as improved skin appearance.

What evidence suggests that the triLift/Legend Pro+ Fractional RF System is effective for treating acne?

Research has shown that the triLift/Legend Pro+ Fractional RF System, which participants in this trial will receive, may help treat acne. One study found that 70% of patients experienced excellent to good results, with improved skin texture and fewer acne scars. Another study reported noticeable improvements in skin texture and color, along with a significant reduction in acne scars. The treatment often works quickly, sometimes after just one session, and the effects can last for several months. These findings suggest that this treatment could effectively reduce acne and improve skin appearance. ^{1 2 4 6 7}

Published Research Related to This Trial

Fractional bipolar radiofrequency (RF) treatment using the eTwo™ system showed high efficacy for improving moderate to severe acne scars, with significant improvement observed after 3-5 treatments in 12 patients.

The treatment was well-tolerated, with only mild and transient side effects like erythema and scab formation, and patient satisfaction was high, with 50% reporting satisfaction and the other 50% reporting very high satisfaction with the results.

Both fractional bipolar radiofrequency (RF) and fractional erbium-doped glass treatments significantly improved atrophic acne scars in a study of 20 Thai subjects, with no statistically significant difference in effectiveness between the two methods.

While both treatments had side effects like pain and scab formation, the fractional erbium-doped glass caused more pain and had a longer scab shedding duration, with one case of postinflammatory hyperpigmentation noted only in that group.

Bipolar fractional radiofrequency (FRF) therapy significantly improved atrophic acne scars and reduced acne lesions in 23 Japanese patients over five treatment sessions, with marked improvements in scar volume and a significant decrease in acne lesions compared to baseline.

The treatment was well-tolerated with minimal side effects, and patients reported significant improvements in their quality of life, along with reductions in sebum levels, skin roughness, and scar depth.

The combination of radiofrequency (RF) energy and 410-nm blue light has shown excellent efficacy in treating grade 4 cystic acne and acne scars, with significant improvement noted by both the patient and investigators.

This treatment approach offers a safe alternative to traditional acne therapies, as it minimizes downtime and reduces the risk of negative side effects associated with conventional topical and oral treatments.

The latest generation of radiofrequency (RF) technology, known as 3DEEP, allows for deeper penetration into the skin while minimizing damage to the epidermis, making it safer and more effective than earlier RF devices.

Clinical studies demonstrated that after 6 sessions of multisource RF treatment, patients experienced significant improvements in skin structure, including reduced wrinkles and a long-term reduction in subcutaneous fat thickness, indicating effective collagen remodeling.
