The erbium laser's wavelength finds a natural application in dermatology as well as in dentistry: the full field handpiece completes the PLUSER's dentistry functions and becomes the PLUSER DERMA for the treatment of skin lesions such as acne, scars, lentigo, xantelasma palpebrarum, solar keratosis, warts, nevi, melasma and cysts. The erbium laser provides complete vaporization of the epidermis, while non-ablative lasers do not. In addition to stimulating the contraction of collagen, this process activates the wound healing response for better results. The excellent results are immediately evident and healing is much faster.
