The technology Q-switched Nd:YAP (1079/539nm)

 The q-switched Nd:YAG Applicator is the ideal choice for the treatment of pigmented lesions, such as sundamaged skin and age spots, and for the removal of unwanted tattoos.

Medilas_content_da Nd: YAG 1064nm : ideal for treating dark tattoos, dermal pigmented lesions, and for skin resurfacing. Nd:YAG/KTP 1064/532 nm : optimal for bright colored tattoos and solar lentigines, it is also used for vascular lesions, including facial and leg vwins, telangiectasias, and angiomas.

Erbium YAG ( 2940 nm)

The Erbium YAG Applicator is able to remove microscopic layers of skin, producing outstanding results with minimal risk and adverse reactions. The laser can remove both superficial and medium depth lines, including some scarring, depending on the controlled depth of the oblation and the amount of treatment performed. The Erbium YAG Fractional procedure produces thousands of deep, tiny columns in the skin. It works on old epidermal pigmented cells without affecting the surrounding tissue, thus reducing healing time (about 24 hours) and promoting the skin’s natural regenerating process. It is a safe, non-invasive procedure that allows fresh, healthy young skin.

The use of Q-switched Nd:YAG laser in the treatment of superficial pigmented lesions in Koreans

. Methods: A total of 71 patients, presenting a wide gamut of super¬ficial epidermal lesions, were treated with OSNYL. Clinical responses were assessed by comparing photographs that were taken serially in every treatment.

. Results:  Treatment using the OSNYL is reported individually for the various superficial pigmented lesions in the skin of Korean patients.

. Conclusion: OSNYL may be a bene¬ficial alternative tool for the treat¬ment of a number of benign pigmented lesions including freckles, lentigines and unilateral lentiginosis. (J Dermatol Treat (2001) 12: 91-96)

This principle has led to the cre¬ation of a series of laser systems, including red light lasers (i.e. alexandrite, neodymium:yttrium-aluminium-garnet [Nd:YAG], ruby), and green light lasers (i.e. 510 nm pulsed dye, 532 nm frequency-doubled Nd:YAG), which can specifically target such pigmented lesions.

The goal of this study was to follow a large number Korean patients with various superficial pigmented lesions through laser treatment in order to analyse the efficacy and side effect profiles of QSNYL in the various superficial pigments removed in Korean patients

Patients and methods

. Patients

A total of 71 Korean patients presenting with a wide gamut of superficial pigmented lesions consented to participate in our study

We operated the QSNYL at 532 nm with a pulse width of 5-7 ns using a 3-mm spot and a repetition rate of 10 Hz. The fluence ranged from 1.1 to 4.4 J/cm2, with a mean fluence of 2.9 J/cm2

No local anaesthesia was administered to adult patients, while EMLA cream (eutectic mixture of local anaesthetic; Astra Pharmaceutical Production AB, Sodertalje, Sweden) was applied 2 h before treating chil¬dren. A silicone-coated lead shield was placed over the ocular globe in cases of treating lesions near the eyes. To reduce swelling and pain, we recommended ice compres¬sion for 20-30 min after laser treatment.

Within 1-2 weeks, all lesions formed thin, dark-brown crusts that were separated spontaneously. Sunscreen and 4% hydroquinone creams were then applied until the next treatment in order to minimize reactive hyperpigmenta-tions.

The interval between each treatment session was 3 months. We recommended that all the patients visit our clinic again 3 months after the last treatment

. Results

.. Solar lentigo

A total of 10 (83%) out of 12 patients with lentigines showed good to excellent responses to treatment with QSNYL with 1.6 or 2.7 treatments (Figure 1, Table II). Two patients showed fair results; there were no poor results

.. Freckles

All four patients treated for freckles showed excellent or good responses with QSNYL with one or two treatments

.. Melanotic macules

Seven (35%) out of 20 patients were judged to have experienced an excellent response (Figure 2). Two patients (10%) each showed good and fair responses, whereas nine (45%) patients showed poor responses. The average number of treatments for those patients showing an excel-lent result was 3.4, whereas for those with poor results it was 2.0.
