Dermatologists Warn of Risks Associated with Treatment to Boost Skin's Collagen Production

In today's world, there are numerous options to combat the visible signs of aging. Treatments range from surgical procedures like facelifts to topical products such as retinol and chemical exfoliants. Between these extremes lie non-invasive and minimally invasive procedures, including laser skin tightening, baby Botox, and ultherapy, which refresh the complexion without surgery. Among these, one procedure has recently gained popularity among celebrities and influencers: radiofrequency microneedling.

This is one of my preferred cosmetic treatments, says Helen He, MD, assistant professor of dermatology and director of lasers and cosmetic surgery at Mount Sinai. I perform it frequently.

Other specialists include Arash Akhavan, MD, a board-certified dermatologist in New York City, and Akshay Sanan, MD, a double board-certified facial plastic surgeon with practices in Boston and Chestnut Hill, Massachusetts.

Online, radiofrequency microneedling is often promoted as a solution for many skin concerns. However, the FDA recently issued a safety alert about potential complications associated with certain uses of these devices. Despite this, experts agree the treatment is generally safe when administered by a trained professional.

What is Radiofrequency Microneedling?

Radiofrequency microneedling (RF microneedling) combines microneedling with radiofrequency energy to stimulate skin rejuvenation. It merges two established technologies in one procedure, explains Dr. Sanan. The process uses a handheld device with extremely fine needles that puncture the skin to create micro-injuries. As the needles penetrate, they release radiofrequency energy that heats the tissue, enhancing collagen production beyond what microneedling or radiofrequency alone can achieve.

Benefits for the Skin

Though it may seem counterintuitive to injure the skin to improve its appearance, RF microneedling encourages the body to repair itself more vigorously. The micro-injuries trigger collagen and elastin production, while the added heat further stimulates tissue remodeling over weeks or months. Results are gradual and usually require a series of treatments, typically three sessions spaced four to six weeks apart.

• Reduces wrinkles: By promoting collagen and elastin synthesis, RF microneedling helps diminish fine lines and wrinkles over time.
• Improves skin firmness: The treatment helps combat sagging caused by collagen loss, supporting a more toned and lifted appearance.
• Refines texture: The procedure encourages skin cell turnover, reducing the appearance of pores, smoothing scars, and enhancing overall texture.
• Minimizes acne scars: Collagen generated during healing can fill in depressed scars, softening edges and improving skin smoothness.
• Hydration benefits: Some studies suggest RF microneedling may increase hyaluronic acid production, helping maintain plump and moisturized skin.

The procedure is generally well-tolerated, with patients experiencing mild discomfort, often managed with numbing cream or injections. Sessions are relatively short, typically lasting 1520 minutes for the treatment itself, with minimal downtime. Redness, swelling, and faint grid marks may last two to five days.

Risks and Safety Considerations

While RF microneedling is safe in skilled hands, complications can arise if performed improperly. Common risks include:

• Burns and scarring: High device temperatures can damage tissue if not correctly managed.
• Hyperpigmentation: Skin may darken temporarily, particularly in individuals with darker skin tones.
• Fat loss: Excessive heat can damage subcutaneous fat, potentially creating a hollowed appearance.

The FDA advises treating RF microneedling as a medical procedure requiring a qualified professional. Providers should customize the treatment for individual needs rather than using a one-size-fits-all approach.

Conclusion

RF microneedling offers collagen-boosting and skin-enhancing benefits when performed safely by an experienced dermatologist or plastic surgeon. Results are gradual and subtle, so managing expectations is key. Choosing the right provider and understanding the procedures limitations are essential to achieving safe, effective outcomes.
