Lasers can improve inflammatory acne, but they are not first-choice treatment in October 2026. Topical benzoyl peroxide, retinoids, and isotretinoin for severe disease carry stronger guideline support. The devices discussed here are energy-based treatments for acne, meaning light or laser energy heats skin targets to reduce breakouts. The newest option uses a 1726-nanometer diode laser tuned to sebum, the oil that feeds clogged pores and gland activity.

Do dermatologists recommend lasers first?
No. The American Academy of Dermatology's January 2024 acne guidelines found evidence insufficient to recommend lasers and light devices, while strongly backing benzoyl peroxide, retinoids, and isotretinoin for severe disease, according to the Medscape summary of the guidelines. That means drugs remain the starting point for most people.
Lasers fit better as an add-on or an option for people who cannot tolerate or prefer to limit drugs. A dermatologist can match severity, scarring risk, skin tone, and cost to the choice. Bring a list of past prescriptions and how skin responded.
How does the 1726-nm acne laser work?
The 1726-nm wavelength selectively heats sebum because sebum absorbs about 1.2 times more than water at that wavelength, injuring oil glands while contact cooling protects the surface, as described by Skin Therapy Letter in the review of 1726-nm laser action. Less active glands make less oil.
Less oil means fewer clogged pores and inflamed pimples. The FDA cleared Cutera's AviClear 1726-nm diode laser on March 24, 2022 for mild, moderate and severe acne, the first energy device with that broad acne indication, according to the Nasdaq-published FDA clearance notice. The FDA later cleared AviClear and Accure's 1726-nm systems for long-term treatment of inflammatory acne, with Accure's expansion in October 2024 after sustained lesion reduction.
How long do results last?
A prospective multicenter study reported in the Journal of the American Academy of Dermatology found reduced moderate-to-severe facial acne persisting at least one year. The authors supported use for patients wanting non-drug or adjunct therapy. That durability matters for people worried about daily pills or long antibiotic courses.
It does not mean permanent cure, and touch-ups or topical care may still help. Results vary by severity and hormones, picking, and skin care. Photos at baseline and follow-up visits help judge real change.
What can other lasers and light devices do?
A 2025 systematic review found vascular lasers including pulsed-dye, IPL and Nd:YAG significantly improve inflammatory acne, with fractional CO2 showing about 88% lesion improvement, according to the PubMed systematic review record. Adverse effects were usually mild transient redness and pain. Comparative trials found 1064-nm Nd:YAG and 595-nm pulsed-dye laser equally effective for inflammatory lesions, with Nd:YAG sides showing fewer adverse effects.
Pulsed-dye carries risks of pain, edema, purpura and post-inflammatory dark marks, a concern for darker skin tones. Redness-prone or post-acne marks may favor vascular targeting. Pitted scars may need a separate scar plan, not an acne-flare device.
What does treatment involve?
The practical course is typically three 30-minute 1726-nm sessions over about 3 months, often combined with topical or oral therapy rather than replacing it. Sessions use cooling and eye protection, with brief heat and redness during treatment.
Limitations are limited head-to-head data, small samples, and variable access. If flares persist after three months, ask whether to adjust drugs, spacing, or maintenance.
- Ask whether you still need retinoid, benzoyl peroxide, or hormonal care alongside laser
- Ask about pain control, sun avoidance, and makeup rules after each visit
- Ask about total out-of-pocket cost, since coverage is often limited and access varies
- Ask what evidence applies to your acne type and skin tone
