You may experience some discomfort during either treatment. The sensation of a Fraxel laser treatment has been described as an intense prickling. We can apply a topical numbing cream if desired. You can also take an oral painkiller, and we can prescribe one for you if needed. The depth of the needling during The Eraser treatment is adjusted based on the severity of your stretch marks. For treatments with shorter needles, only a slight sensation will be felt – similar to a tickle. When longer needles are required, a numbing cream is applied to minimize discomfort.
