Efficacy High power to dermis: more energy to follicles, vessels, collagen, sebaceous glands. High power absorption in epidermis: less energy to deep dermal structures.
Comfort Less painful due to shorter pulse durations. Very painful due to tendency to super heat epidermal melanin. Skin cooling gels or equipment needed.
Risk of Side Effects Safe on all Skin Types. Higher risk of burning skin; not recommended for use on skin types 4-6 or tanned skin because of pigmentary risk.
Consumables Few or none. Frequent head replacements (on average after 30,000 pulses), filters and gels – annual cost $5,000-$10,000.

  • An evaluation of the efficacy of a 1064-nm neodymium-doped yttrium aluminium garnet (Nd:YAG) laser using lower than traditional fluences (22-40 J/cm2) for treatment of pseudofolliculitis barbae (PFB) was completed by the Dermatology Department of the Naval Medical Center San Diego, San Diego, California.

    Twenty-two (22) patients with PFB refractory to conservative therapy received five weekly treatments over the anterior neck using a 1064-nm Nd:YAG laser at 12 J/cm2. Pulse duration was 20 ms with 10 mm spot size. Topical anesthesia was not used. Treatments were completed 15 minutes after patient arrival. Patients presented for 2- and 4-week follow-up. Ten evaluators used a Global Assessment Scale (GAS) to assess dyspigmentation, papule counts, and cobblestoning by comparing baseline to 4-week follow-up visit photographs. Hair and papule counts were performed on five patients and compared with the GAS. Investigators recorded adverse effects using a visual analog and side effects scale.

    RESULTS

    Eleven (11) patients demonstrated 83% improvement on the GAS (p<.01). There was a mean reduction of 59.5% in dyspigmentation (p<.03), 91.2% in papule count (p<.01), and 75.6% in cobblestoning (p<.02). Patients reported 1 out of 10 on both adverse effects scales.

    CONCLUSION

    Low-fluence 1064-nm laser treatment achieved significant temporary reduction in PFB. Subjects noted minimal pain without topical anesthesia.
