**2.3 UVA1 target laser in children**

Another optional treatment modality could regard as UVA1 target laser consists of an active medium and a Neodymium-doped yttrium orthovanadate (Nd:YVO4) crystal that is "energetically pumped" by another laser with 808 nm wavelength divided sequentially second (532 nm) and third (355 nm) harmonic wavelength delivery. Laser Alba allows the treatment of limited boarded lesional skin areas so that clinician can use a more appropriate dose of energy, leading to shorter duration and less frequent treatment sessions. The treatment with Laser Alba 355 is well—tolerated and already known acute side effects, such as erythema or pruritus have rarely been described.

Furthermore, innovative modalities consist of excimer laser, focused microphototherapy and also Laser ALBA should investigate to create new options [27, 29].
