Do I need to use anesthesia or A numbing agent?

This will depend on the actual treatment itself. If you are going for a subablitive peel or a micropeel (Aerolase Era for Superficial Ablation) topical anesthesia may not be needed, but this should be determined and mutually agreed upon by both patient and practitioner. For sun damage and deeper wrinkles (Aerolase Era for Medium Depth Ablation), the use of topical anesthetics is required. For deep wrinkles and extenseive sun damage (Reveal), local injections or nerve block is recommended.
