Skin resurfacing and rejuvenation treatments can be performed either in ablative modes with an Er:YAG laser or non-ablatively with a Nd:YAG laser, depending on the particular aesthetic outcome that the patient and practitioner wish to achieve. In addition, ablative and non-ablative treatments can also be combined into a comprehensive anti-aging treatment, such as Fotona’s TwinLight™ Fractional Rejuvenation system.
