clinical roundtable | RevLite Today, the RevLite is not only a preferred gold standard among Asian physicians for pigmentary issues, it stands apart as a multi-wavelength aesthetic laser that treats a wide-range of indications. The RevLite ® EO Q-switched Nd:YAG laser from ConBio, A Cynosure Company (Fremont, California, U.S.), is an evolutionary step in the Company’s MedLite ® series of lasers, which transformed the Asian aesthetic industry 20 years ago. Today, the RevLite is not only a preferred gold standard among Asian physicians for pigmentary issues, it stands apart as a multi-wavelength aesthetic laser that treats a wide-range of indications. In darker skin types, photodamage usually presents as pigmentary changes, rather than wrinkling. This is in part because these patients have a higher epidermal melanin content, which can predispose them to an increased risk for epidermal and dermal pig-mentary disorders. Asian patients are prone to several of these conditions, such as me-lasma, freckles and lentigines. Other, typical dermal hyperpigmentation disorders in-clude Nevus of Ota and acquired bilateral macules (Hori’s Nevus). The RevLite treats these lesions, sun damage, rough or uneven texture, large pores, age spots, and other signs of aging or discoloration that are also widespread among patients in Asia. Post-infl ammatory hyperpigmentation (PIH) is another common problem that can be treated with the RevLite. PIH includes acne, which is prevalent among Asians and can be quite severe, causing dramatic scarring. Other treatment indications include fi ne, vellus hair removal; improvement of vascular lesions; tattoo removal, which in this re-gion tends to focus on permanent make-up and other cosmetic tattoos; and skin reju-venation of the face, hands and chest. Utilizing the same core technology found in the MedLite, the RevLite emits ex-tremely short pulse durations of 5 ns to 20 ns, which induces a PhotoAcoustic effect while reaching very high energies of over 200 megaWatts (mW) per pulse. RevLite’s proprietary PhotoAcoustic Technology Pulse ® (PTP) setting allows practitioners to harness very narrow pulse widths at peak energy, offering as much as 60% more power and up to 1.6 joules (J). PTP mode enables delivery of high-energy nanosec-ond pulses into the dermis without producing acoustic damage to the epidermis, thereby delivering optimal results for non-ablative skin rejuvenation. With a repetition rate of up to 10 Hz and spot sizes up to 8 mm, the RevLite pro-vides very fast treatments. As a frequency-doubled laser (1064 nm and 532 nm), it can offer up to four wavelengths with additional handpieces available at 585 nm and 650 nm. During treatment, it uses a fl at top beam profi le that nearly eliminates power spikes or hot spots, delivering energy evenly along the surface of the skin. RevLite targets the chromophore with the PhotoAcoustic effect, which vibrates and shatters the pigment, but does not affect the surrounding tissue. Editor’s Note: In the following clinical roundtable, fi ve aesthetic practitioners in the dermatolog-ic and cosmetic surgery fi elds from Asia discuss the RevLite system. Participants included Philip Bekhor, M.D., director of the Laser Unit in the Department of Dermatology at Royal Childrens Hospital in Melbourne, Australia; Fan Xin, M.D., director of the Dermatology Department at Beijing Military General Hospital in China; Atchima Suwanchinda, M.D., a dermatologist, dermatologic surgeon and director at the Medisci Biointegrative and Anti-Aging Center in Bangkok, Thailand; S.C. Rajendran, M.D., D.V.D., a dermatologist and professor at the Vydehi Institute of Medical Sciences and Research Centre in Bangalore, India; and Peter Wong, M.D., consultant plastic surgeon at Timberland Medical Centre in Sarawak, Malaysia.
