Le phototype doit \u00e9galement \u00eatre \u00e9valu\u00e9, ainsi que les ant\u00e9c\u00e9dents d\u2019hyperpigmentation, d\u2019herp\u00e8s ou de cicatrisation anormale.<br \/>Apr\u00e8s la s\u00e9ance, les soins varient selon le laser utilis\u00e9. La zone trait\u00e9e doit notamment \u00eatre prot\u00e9g\u00e9e du soleil et les \u00e9ventuelles cro\u00fbtes doivent tomber spontan\u00e9ment, sans \u00eatre arrach\u00e9es.<br \/>L\u2019American Academy of Dermatology recommande d\u2019\u00e9valuer le type de peau, les caract\u00e9ristiques de la cicatrice et l\u2019\u00e9tat de sant\u00e9 du patient avant un traitement laser afin de limiter le risque d\u2019effets ind\u00e9sirables.<br \/>Les suites les plus fr\u00e9quentes sont une rougeur, un gonflement, une sensation de chaleur et, avec certains lasers, la formation de cro\u00fbtes. L\u2019hyperpigmentation constitue un risque particuli\u00e8rement important chez les phototypes fonc\u00e9s. Les infections, les troubles pigmentaires persistants et l\u2019aggravation d\u2019une cicatrice sont plus rares et n\u00e9cessitent une prise en charge m\u00e9dicale
