There is little to no real downtime with The Eraser treatment. You may experience sunburn-like redness and/or mild swelling on treated areas for a few days. You should treat your skin gently for the next week or two by avoiding sunlight and using mild products. Fraxel treatments require more post-treatment care. Your skin will be sensitive and will need to be protected from the sun for about 4 weeks. Any swelling will be minimal and can be treated with cold compresses.
