How I Treat Acne with VBeam Prima

Acne vulgaris is the most common skin disease worldwide and inflammatory acne has a significant psychological impact with potential for long-term emotional and physical sequelae. (1)
Energy based treatments are useful both as adjuncts to traditional therapies and particularly for patients unable or not amenable to antibiotic, hormonal or retinoid based topical or systemic therapy.
Simply stated, the acne lesion is a result of defective keratinization of the follicular duct resulting in a distended sebaceous follicle which becomes plugged with sebum and debris. Propionibacterium acnes (P.acnes) bacterial overgrowth perpetuates the lesion and contributes to inflammation. Inflammatory lesions, papules and ustules can be large and tender and when persistent over time can lead to scarring.
Pulse Dye laser treatments at the 595nm wavelength (VBeam, VBeam Prima) are indicated for the treatment of acne vulgaris and the mechanism of action is multi-fold. Erythematous papules and pustules have both a vascular and inflammatory component and VBeam has long been shown to be a safe and effective gold-standard technology for the coagulation of vascular lesions. The inflammatory component is improved as PDL energy upregulates TGF-beta, a potent immunosuppressive cytokine. (2) Moreover, reduction of P.acnes by the 595nm wavelength effectively targets porphyrins inducing thermal damage to the bacteria. (3)
Our patient population includes both male and female patients over a range of ages from adolescence through to the peri-menopausal period. VBeam is our laser of choice as a safe an effective treatment. Cryogen cooling effectively cools the epidermis and provides comfort especially for our adolescent population. The 595nm wavelength does not have any depilatory effects and can also be used in males without concern for reduction of facial hair. Reduction in lesion size and inflammation is noted rapidly with significant reduction within the first 24 hours after therapy.
Protocol pre-treatment involves holding any topical or retinol therapy two to three days prior to treatment and can be resumed the day after treatment. Immediately prior, the skin is prepared by thoroughly cleansing and drying.
Typical parameters are as follows:
Spot Size between 7-15mm. Smaller spot sizes are only selected in the case of discrete lesions in darker skin type patients up to Fitzpatrick skin type IV.
Otherwise, the 13-15mm spot sizes of VBeam Prima are used to cover the full face overall acne prone areas in two passes. The first pass is a generalized pass with the pulse duration of 6ms and energies from 6-7 J/cm2. The second pass covers discrete lesions using 10-15 mm spot size selected depending upon the density of the lesions with a 3ms pulse duration and 5-6.5 J/cm2. DCD is used with a 30ms spray and 20 ms delay. Slight darkening and erythema of the inflammatory lesions is noted as a treatment endpoint. The skin is cooled afterward and sun protection is applied.
The zoom handpiece and single calibration capabilities of the VBeam Prima make the treatment very fast and easy to apply. The larger spot sizes also increase speed and decrease the number of pulses required for the patient.
Improvement is noted after a single session and the protocol involves monthly treatments for 3-5 sessions for mild to moderate cases. For optimal results in patients with more significant inflammatory lesions, treatments are scheduled every two-three weeks. Once control is achieved, which is typically within 6-8 weeks, the duration between sessions is lengthened to monthly intervals.
Treatment of such an important condition is safe, effective and easily applied with the VBeam Prima.
