Update on New Laser Treatments for Acne

Newly approved laser treatments can be an effective option for the treatment of this common skin disorder.

One of the most common conditions encountered by dermatologists,1 acne is a disorder of the pilosebaceous unit that is characterized initially by comedones, which can progress to papules, pustules, nodules, and even abscesses. Its pathophysiology consists of several processes, including follicular hyperkeratinization, microbial colonization, sebum overproduction, and inflammation. Because sebum is the substrate on which the bacteria that contributes to acne grows, the sebaceous gland plays a key role in acne pathophysiology. Some studies have shown that compared with normal patients, those with acne have both hyperseborrhea (elevated sebum) and dysseborrhea (altered sebum composition).2 These physiological changes favor Cutibacterium acnes overgrowth and biofilm formation, stimulate subsequent inflammation, and disrupt follicular barrier function, ultimately causing comedogenesis. As sebum and keratinocytes interact, a keratotic plug gradually forms and blocks the pilosebaceous ducts, creating a comedo, the precursor to most acne lesions.

Given this multifactorial pathophysiology, treatment options include topical and oral antimicrobials, topical and systemic retinoids, benzoyl peroxide, oral contraceptives, and oral antiandrogen therapies. Many acne regimens require months of topical and systemic therapies, have adverse effects (AEs), and lead to antibiotic resistance and to poor patient compliance. Concentration-dependent AEs like irritation are seen with topical therapies, and oral medications must be used cautiously in certain patients. In addition, many of these medications are effective at treating symptoms and flares but cannot prevent outbreaks.

It’s therefore imperative to augment the acne armamentarium with nonpharmacological therapies. Energy-based therapies have the potential to mitigate the AEs associated with traditional oral and topical treatments. Already in use to treat acne sequalae, the technology has recently been approved for mild, moderate, and severe acne.3,4 Laser therapy, specifically with the 1064 nm Nd:YAG laser, is beginning to be recognized as a safe and effective option that has the potential to work quickly with reduced rates of recurrence.5

A recent randomized controlled trial used a split face design to compare the efficacy of intralesional platelet-rich plasma (PRP) injections versus 1064 nm long-pulsed Nd:YAG laser and concluded that the laser was safe and effective for controlling inflammatory and noninflammatory acne lesions.6 Pulsed dye laser (PDL), which has been used to treat rosacea and port-wine stains, has also been studied in acne. A systematic review and meta-analysis found that 4 or more treatment sessions with PDL could significantly decrease acne severity scores.7 Compared with other devices, the Nd:YAG laser is supported by more high-level studies.8

The energy-based treatment of acne has improved with the recent approval of the AviClear (1762 nm wavelength) laser, which targets sebaceous glands and is the first device cleared by the US Food and Drug Administration (FDA) for mild-to-severe acne.9 Studies have demonstrated that selective destruction of sebaceous glands with electrothermolysis is a safe and effective method for treating acne.10 A randomized, controlled trial involving 63 patients showed that, compared with the control group, the treatment group—which received 3 electrothermolysis treatments at 4-week intervals—experienced a significant reduction of inflammatory acne lesions at week 12, as evaluated by 2 independent physicians.11

Such research studies have pioneered the treatment of acne with energy-based devices. “Sebum-specific wavelengths are the latest advances in device-based treatment for acne. These lasers are selective and penetrate deep enough to cause thermal damage to the pilosebaceous unit without heating surrounding skin and…provide long-term effective control of acne eruptions,” said Girish S. Munavalli, MD, MHS, FACMS, medical director of Dermatology, Laser & Vein Specialists of the Carolinas and assistant clinical professor of dermatology at Wake Forest School of Medicine.

Although these novel therapies offer great promise, their price may prove to be an obstacle for certain patients. By some estimates, these treatments can cost thousands of dollars per session.12 According to Munavalli, “out-of-pocket expenses for laser treatment of acne will continue to be the case, as they are unlikely to be insurance-reimbursable.” In addition, when offering these procedures, it is important to discuss the data on their long-term safety and efficacy. As Munavalli explained, although “long-term (greater than 1 year) data is still pending,” but looks promising for preventing the development of new acne.” Patients should be encouraged by this fact because preventing flares means inhibiting difficult-to-treat sequala like scarring and post-inflammatory hyperpigmentation.

Great progress is clearly being made with energy-based acne treatments. Given how common the condition is, innovative strategies are always welcome. But the technology may be particularly useful for patients with limited options, like those who are pregnant and cannot take advantage of most of the oral or topical therapies available. Moreover, energy-based therapy is often combined with other treatments and can have a synergistic effect. It will be exciting to see how this technology is integrated into the antiacne armamentarium. Although more research and long-term safety data are needed, this modality is a great innovation in the effective treatment of acne.
