In addition, as a non-ablative modality, Thulium lasers complement for the disadvantages of ablative lasers such as CO 2 or erbium, which often lead to longer down time, high risk of thermal injury, PIH (post-inflammatory hyperpigmentation) or/and scarring. Although 1927nm thulium lasers are categorized as non-ablative modality, ablation degrees with Lavieen can be adjusted from non-ablation, sub-ablation to ablation by separately controlling power and pulse duration as the utmost advantage with Lavieen. The physician allows to apply delicate parameter settings and to effectively treat various indications of epidermal pigmentary disorders (i.e. lentigines, age spots), melasma, scars, superficial wrinkles and many. In addition, with this feature, the operator can perform a customizing skin resurfacing by controlling downtime and clinical outcomes, taking into account patient needs. For instance, low power and short pulse duration histologically show non-ablative effects in the skin, tissue denaturation with maintaining stratum corneum intact. Such non-ablative effect causes almost no erythema and edema, resulting in brightening effects showing within 3 days of the procedure day. S KIN RESURFACING and rejuvenation is a steadily growing market in the medical aesthetic field. Fractional lasers have been widely used for skin resurfacing, skin rejuvenation, and other indications since the early 2000s and treatment using fractional lasers has shown to be effective. I have been using Lavieen, a unique 1927 nm Thulium fractional laser developed and manufactured from Wontech, Co, Ltd. (Daejeon, South Korea). This laser system is excellent for aesthetic medical applications with its versatility, efficacy, and safety in that it can treat various indications for all skin types and ages. The 1927nm wavelength has a higher absorption co-efficient to water than that of Er:Glass therefore its penetration depth is superficial to the epidermis, especially the target layer is at the stratum basale where melanin is present. It acts as the shuttle of melanin in the heat of microscopic epidermal necrotic debris (MEND), effectively treating epidermal pigmented lesions (i.e. lentigines, age spots) as well as brightening effects. With a single procedure of Lavieen, patients experience great improvements in skin resurfacing; improved uneven skin texture, dull skin tone, and superficial pigmentations. This is why Lavieen is also widely known as B.B (Blemish Balms) laser, which is similar to the make-up effect of applying B.B HaewoongLee discusses the range of applications for the Lavieen laser system technology fromWontech Sub-ablation effects by moderate power and pulse width lead to 5 day down time with mild to moderate erythema and edema, and bring outstanding results in skin resurfacing. Device applications Laser-assisted drug delivery is commonly done with Lavieen; the Lavieen delivers fractionated laser beams to the skin in order to create microscopic wounds, which are also called microscopic necrotic columns (MNCs) and these columns enhance cosmeceuticals permeability into the skin. By applying a cosmeceuticals followed by a Lavieen procedure, the patient is promised synergistic effects with the solution that restore and regenerate the skin. For drug delivery, any cosmeceutical compounds can be applied after a Lavieen procedure including vitamins, EGF, FGF, hyaluronic acid and more. Even fillers or Botox can be applied. Since Lavieen has features of non-ablation effect and separately controlling energy and pulse duration, it can easily be used with other energy-based devices such as a picosecond laser, RF needles and extras. Combined therapies that utilize Lavieen do not make the physicians worry about longer HAEWOONG LEE, MD, PHD , at Louis Dermatologic Clinic, South Korea PROMOTION LAVIEEN AN OUTSTANDING METHOD FOR SKIN RESURFACING AND REJUVENATION “This laser system is excellent for aesthetic medical applications with its versatility, efficacy, and safety in that it can treat various indications for all skin types and ages.”
